air purifiers

I just bought this humidifier last night and I have to say this thing did its purpose! I have allergies and am in between moving so my room is a little more dusty than usual. It cleared the air and I was able to feel the crisp clean air in my room. The noise is tolerable and overall this machine is definitely worth it. see less

Have had this for a week so far and it works great. quiet on low and I have no trouble sleeping at night while it runs.I live in Chicago area and got this due to the basement that is always very musty smelling and this did the trick !! I could not afford one of the expensive ones and this one works great ! see less

I bought this because I have mild allergies to dust, pollen, mold, etc. and hoped this would help. This filter comes with a Total Air filter, but only the Allergen replacement filters are true HEPA filters, which is what I need. The filters to pick up a lot--within a week the filter was black with who knows what! I breathe easier now knowing that this is picking out all of the things I don't want to breathe in. I've had this for about a month and am very happy with it. see less

Runs quiet and clean air very well. I can see less dust on my drawers now compare to before. Worth the money! see less

We have seen a huge improvement in our air quality at home. I have to say we were really surprised! We have two pets, a cat and a dog. This has really helped with all the pet dander and my children have stopped coughing at night. We love this Air Purifier. It really is a great product. We are breathing a lot better! see less

My wife was having serious health problems which were related to allergies and a lung infection. The air purifier has definitely helped in keeping pollen as well as dust and other airborne items clear from the area. I can tell not just from the improvement we both felt in breathing but very little dust settles on tables in the area. Highly recommend the Ionic system for its ease of setting up and its noiseless operation. see less

i received this as a gift for my daughters nursery and it works perfectly. I have it constantly running on at least the 2nd setting and don't find it too loud at all. In fact it is still quiet enough that she sleeps with it going every night. We have both cats and neighbors who smoke and the air in her room is considerably "fresher" then the air in the rest of the home. I would recommend this for anyone who is looking for a quality purifier that will last. see less

This is a TRUE HEPA, not ... see more

This is a TRUE HEPA, not a HEPA-type filter, and if you're concerned about air quality you shouldn't ignore the difference. There is a very noticeable difference in volume between the 3 fan settings. High is about as loud as a hairdryer on its lowest setting, Medium is about half as loud --try a hairdryer on regular setting in the next room with the door closed-- and Low is very quiet, you won't hear it if there's any ambient noise. In silence the Low setting sounds like a breeze. The airflow can be pretty strong. I keep it on my desk, if I face it toward the wall and turn it on High it blows the papers off my bookshelf 4ft away, on Low it ruffles papers about 1.5ft away. I've had it a month and keep it running 24/7, usually on Low when I'm home and Medium when I'm out, and it's still working perfectly. see less

I admit, I am a penny pinching, "do I really need it" type of person. It was kicking into spring where I live & I live with my 19 YO brother as a roommate who doesn't shower or clean his room so there is a lot of mold growing in his room. I am 24 YO, I have some of the worst allergy symptoms and can always decipher between a want v. a need. One day my allergies got bad! I was sneezing, eyes were blood shot red, my nose was running so much it started to bleed from all the sneezing & I take prescription allergy medication. I went out and bought one of these& the allergen filter that last 12 months & it started working within the first 5 minutes after I set it up. The next day I went out, bought 2 more but the bigger sized ones. Yes, the item with the filter was expensive but as I've had it now 2.5 months, I have cut down on other expenses in the long run i.e. tissue, soaps etc because of this item! It has been one if not the best investment I have made & 110 percent worth it!!!! see less

Filters are 15bux, need to change them 4x a year, 5bux a month to run. Was on sale for 40bux at my local Target. Exactly what I'm looking for. Quiet, 3 fan settings, perfect size, 2 color options... What more can you ask for? see less

My mom gave this to me as a Christmas gift in Dec. 2011. I keep it running constantly in my bedroom. It provides a mellow white noise that helps me sleep and it definitely helps manage dust and pet hair. However, I cannot find replacement filters! I found them once at Target and bought two packages that have lasted me until now. Can't find the filters at Target, and I just went through 16 pages of search results from Amazon and they don't have the filters either. Looks like I will have to replace this machine with another model that has easily findable replacement filters. Bummer. see less

This odor eliminator is a ... see more

This odor eliminator is a godsend! I have 3 huge indoor/outdoor dogs (two of them are German Shepherds), and no matter how much we wipe them down, the "dog" smell lingers. We have a Holmes air purifier, but it really isn't doing anything with the dog smell- it's only good for the pet dander. I decided to try it out since it's pretty cheap, and the reviews were amazing. At first I thought It wasn't working, but give it a few hours, and you've got fresh clean air! I hated buying candles, carpet deodorizers, air fresheners for it to work temporarily. I'm on my third day of using it, and I'm so glad I bought it! see less

My husband and I were so ... see more

My husband and I were so pleased by the effectiveness of this odor eliminator in my son's room, that we bought another one for the "Cat room"! It gets rid of ALL smells! The night light is a nice feature because it allows me to feed my son in the middle of the night without turning on the table lamp. Anything that reduces the risk he'll fully wake up is a bonus in my book! The filter needs to be changed about once every three months, if you have it on all the time (which we do), and the white noise that it produces is very minimal and soothing. see less

I have 4 of these honeywell air cleaners , if u don't have one. ., The dust stuff that a vacum picks up, well you would not believe how much of that is in the air, no order also, my unit is the 78000 it has the round look, Target has the best price [$] compared to [$] at crowders do,they don't even hey dont even have the replacement filter for the same unit , Maintainence is easy, I change the filter every 2-3 months, your air in the house wil be totally differernt. see less

I have 2 in the living/dinging room, & one in each room (tabletop in bathrooms), do not need one in the kitchen, the 2nd one in the main room (dining room) covers that too., The 1st 2 I got (due to many allergies from radiation treatment), I put in the main room , one wwould cover the area, but when you change the carbon filter for the 1st time, you would not believe what was on the filter , well, you know the stuff your vaccum picks up ? When I opened it the 1st time , there must of been @ least 2inches of the same thing , you find in your vaccum bag, & you know when the window shades are open , all the specs you see in the air, using this air cleaner , they are gone, that stuff in the air is dust mites, very economical ( the only other price I have seen @ most store , is, says change every 3 monthsto run 24/7, & target has the best prices for the honeywell unit, you can not tell, I have 2 house cats & 2 dogs, or smokers, , my model is the 78000, the main core is forever , the black carbon filter is wrapped around it, it says change every 3 months, I change mine every month, due to the animals, & smoking, & dust. Once you try one for only 24 hr. you will not be able to live without them, & Target has the lowest prices for the model , & sometimes goes on sale for 99.00 dollars. With this you will breath easier, & @ 1st , the clean air might make you sleepy, all my friends that have come in my home, went out & bought a few units @ Target. Sincerely,Sandy see less

I bought this for my allergies at the recommendation of my ENT. After doing some research online, I chose this one because it was rated as the best budget item. It's fabulous. I used my FSA money and now I sleep better at night with clean air. It definitely helps that stuffy-ness when I wake up. see less

I like this air purifier a LOT. It is large however, and the light is annoying at night. I wish there was a night switch to turn them off. I do think it is very effective at cleaning the air and would recommend it for the money! see less

I looked at several brands and models and I'm very happy with my decision to purchase this Honeywell air purifier. My apartment only has a few windows and if they have been closed for several hours during the day, when I return I sometimes notice a stuffy odor. This air purifier does a great job of keeping the air fresh and I've noticed my allergies have bothered me less. Easy to operate and easy to clean filter. I just took it out and did a quick rinse. Let it air dry and popped it back in. No fuss, no muss. see less

Myself, my son, and our Boxer -yes, our dog-, have awful seasonal allergies. We also live in Okinawa Japan, where mold, dust, and God only knows what else, run rampant through our 50 year old home. Needless to say, we're in a recipe for disaster. We finally bit the bullet and bought this air purifier about a week ago and couldn't be happier!! It has made a world of difference in our home! The noise isn't bad at all and we run it on high 24/7. I recommend this to anyone in a position to even be questioning it. You won't regret it! see less

i bought one a week ago for my allergies. i was waking up several times a night to blow my nose. when i got it home i just removed it from the boxed and plugged it in. it gave off a odor for the first day, but dissipated. after the first night of use i was able to sleep through the night with no nasal congestion. i would recommend this to all my friends and family. see less

Bought this a few weeks ago and so far so good. My other half has allergies to cats and we have 3 so thought this might help with cleaning the air for him in the bedroom. I don't think we'll ever get all the air pollunts totally gone but it does help with keeping the door closed. We leave it running 24 hrs. a day on high. It's amazing to see how much dust has collected on the filter so far. It's quiet no louder than a fan on low. Wish the cord was a little bit longer. Would purchase again if we need another one for another room. see less

There's poor circulation in my office, so I bought this air purifier hoping it would help with my allergies. I started using it in the office today, and I've noticed a considerable difference. I haven't sneezed once, and I don't feel congested. Even my co-workers have noticed a difference! Why did I choose this air purifier over others? 1. Although there were only two ratings, both guests gave it 5 stars. 2. It's very quiet if you keep it on the first or second setting and not disruptive to me or my cubemates...it's only noisy if you use the third setting. 3. It's compact and doesn't take up much space in my small cube. 4. The price is very reasonable for the quality. see less

this is a very quiet model, and surprisingly small for the area it covers. there are 3 speed settings and i can only hear it on the loudest one. and that too is not that loud. it's barely enough to overpower the ticking of my wall clock. see less

this was quite a bargain, low price plus great quality. Has already lasted longer than the one I purchased elsewhere, and it's super easy to clean. it doesn't make much noise, and it fits in with the room decor. see less

I came across this product on clearance at target and thought i would try it out. Two weeks ago I bought a pre-owned truck which had been smoked in for 6 years. The smell was so overwhelming that I could not go longer than 20 minutes in it. I cracked the window enough to put the extension cord through and let the germ guardian run over night. In the morning when I checked on it there was no smell. I ran the truck with the heater on to circulate the air through the vents (while the germ guardian was on) for about ten minutes to see if it would produce any smell. It did put out a very slight smell of smoke. I ran it again the next night and it smelt great in the morning. This product worked wonders. I forgot to mention that before purchasing I detailed every entire surface of the interior twice! I also put baking soda and vinegar in the truck to get out the smell. nothing worked like this little machine. see less

This air purifier is fahh ... see more

This air purifier is fahhbulous! The filtration system is comprised of charcoal, HEPA, and PCO filters and the UV light tube works to kill germs! I am awfully allergic to dust and pet hair, and my most problematic allergic reaction is shortness of breath, and in some cases, an asthma attack. My bedroom is particularly dusty- I have to clean everything in the room at least once a week to keep that filth at bay! I also have a precious pet rabbit, Deputy BunBun. He is very large(about 12 pounds) and extremely furry! He shares the bedroom with me, as he is my partner in crime (fighting!), so I also have to run the vacuum 2-3 times a week to keep his fur out of the air! I plugged the Germ Guardian in and placed it about three feet away from my bed. I immediately noticed the clean (but very light) scent that was emitted as the purified air exited! For the first time in many years, I got a full night of sleep without having to wake up and take that gawd-awful asthma inhaler. I plan on purchasing the plug in air sanitizer as well! At last, Deputy BunBun and I can breathe the clean air we deserve!Dust, dander, mold spores, plant pollens, particles, bacteria, germs... You are under arrest!!! see less

From the day my daughter was born, this unit has been plugged into the wall between her diaper pail and crib. Not only did it keep any/all odors contained and undetectable, she did not get sick once her whole first year! The very slight humming "white noise" also did a great job of calming her down for bedtime. Love this thing! see less

I purchased two of these today in store. They really do work. One is placed in my basement where the cat litter box is located and the other in the living room where my dog sleeps. There is no dog smell in the living room at all and the basement smells much better. Great product, but you can definitely hear it running. see less

I moved into an upper apartment with two kids. The people who lived here prior to us were huge smokers and there was pet smell lingering. After no success with the landlords I purchased this purifier and the smaller white one for small rooms. I now tell everyone I know about these. I used to have horrible allergies and my daughter has asthma... it's practically knocked out every doctor visit we would have had to go to! You will notice a different smell coming into your house after just a day of them running... that's FRESH AIR you will smell! Amazing and definitely recommend!!! Also, get one for every room while you are shopping, because if you don't you will notice a huge difference in the air between the rooms in your house and will end up going back to the store! see less

We purchased two of the air purifiers, because my husband has severe allergies and asthma. He noticed a difference the night we turned them on. I even noticed a difference the same night with the fresh air. We leave them constantly running in the living area and bedroom. It has three speeds and an ion button. It is nice, because you do not have to have the ion on unless you want. I would definitely recommend! see less

My 1-year-old and I were ... see more

My 1-year-old and I were stuck temporarily in a rental with a mildew problem, and both had chronic respiratory crud. In all honesty I chose the Holmes tower unit with 2 filters just because it had the least expensive filters, among the units rated for allergens and for large rooms. Our symptoms cleared up immediately, and even after a year of use I'm amazed ... In the large living space of another apartment, maintenance used a noxious exterior paint, and this eliminated the fumes in 15 minutes. We use it every night in a very large master suite now--a larger space than its rated for, and everyone wakes up with clearer sinuses. These are the best value among units with comparable specs. After a year we're replacing the filters because we feel we should, not because it seems to need it. see less

I started using an AER1 filter in January in my Holmes Air Purifier when I realized my husband and I were struggling with pet dander. Every morning we'd wake up with puffy, itchy eyes, stuffy noses, and earaches from the congestion. Literally the first morning after switching to AER1 Allergy filter, we had zero symptoms. The filter kept us allergy free inside through one of the worst allergy seasons on record - then about 6 months into our first AER1 filter, we noticed our symptoms coming back, and sure enough the filter was filthy and needed replaced. As soon as we replaced, we were healthy and allergy free in our home. Definitely an AER1 believer! see less

I bought this to replace an old ionic type air purifier that wasn't working too well anymore. This air purifier works MUCH better than my old one. It is very quiet, I have it in my bedroom next to my bed and can sleep fine with it running on medium speed right next to my bed. The only sound you can hear from it is the sound of air moving through it, sort of like a fan. I have had this air purifier for a couple of months now and still haven't had to clean it yet. I have a dog and cat, so I am pleased that the animal hair doesn't get stuck in it and make noise, like my old one did. I am glad I chose this air purifier! see less

Easy set up, fast delivery, and my absolute favorite part - I don't have to replace the filters. I haven't had to clean the filters yet, but it looks like a no brainer job. I have 3 big dogs that shed like crazy and it seems to do the job. My only complaint is that it blows cold air which would be a perk in the summer, but not so much now that the weather is cooling down. It realy could double as a fan! That's the only reason I don't keep it on as much. Otherwise, I'd have it on 24/7. see less

I got this on a whim a few months ago when [brand] and [brand] weren't stopping my allergy symptoms. I put this in my small room and turned it on high- a few hours later there was a noticeable difference. I highly suggest it. A bit noisy on high but the low setting lulls me to sleep. see less

I have terrible allergies ... see more

I have terrible allergies and was looking for an air purifier that would minimize dust and allergens, especially in my bedroom. I also wanted a purifier that was quiet and unobtrusive. After some research, I chose this one and have been very happy with my purchase. First of all, I think it's very quiet - especially on the low and medium speed. It also didn't take long at all for it to catch a lot of the dust in my room, so I am already breathing easier at night. I noticed that it even grabbed a few small dust bunnies that had gathered on my hardwood floors! A bonus of this purifier is that it reduces odors through the carbon filter. This is nice since I live in an older home that can smell musty in places on rainy days. I hope to buy a couple more of these for other rooms in my house! see less

I have had two of these purifiers for over six months and they have done a great job of helping my allergies. There is a huge reduction in the dust and cat hair in my apartment.

BUT does a awesome job and I'm so used to the hum and the light its difficult to sleep without it. see less

I bought this Holmes air purifier at my local Target after owning a smaller Holmes table top one which was not big enough for the room that i now have.After running it for 3 hours i already noticed a big improvement in the air.I would highly recommend this to anyone that wants a air purifier that will do the job. Plus it's easy to buy filters for it since Target sells the filters either online or in the store. see less

Bought this 2 years ago w ... see more

Bought this 2 years ago with some Target gift cards from our wedding since Hubby has bad allergies. He has seen drastic improvements with his allergies since purchasing this product! As others have noted, it can be noisy on the higher settings. We rarely ever turn off our filter and keep it on level 2 or 3 output and we have not had any problems with it.It works really well, but is expensive to maintain especially the HEPA filters. The machine will tell you what filters need to be changed by an indicator light. The carbon filters needs to be changed every few months and the HEPA filters every two years or so. It is convenient that you can buy all the filters at Target, but the manufacturer packages the carbon filters in packs of 4 and you only need 3....and the HEPA filters are EXTREMELY expensive [....] and come in packs of two and you need 3.....I see less

I have tried several different air purifiers and this one is the most for the money. Plus it is by far the quietest even on the highest setting.

I travel 8 months out of the year for work, and I bought this - skeptically - to take with me when I'm traveling for work. I have to say, I'm extremely impressed. It's small enough to fit in my suitcase, it's very very quiet with the exception of a small rattling sound on high - but it's not bad enough to bother me, and probably a result of being thrown around airplane baggage claims. I suffer from serious allergies, this is the first thing I unpack when I check into a hotel. I can tell a difference. If you suffer from allergies, this is a must-have. see less

I have a small house with ... see more

I have a small house with 3 rooms that I wanted to get air purifiers for. I chose the AC4010 since the floor standing models would've been overkill for each room. I bought one unit to try out first and it seems to work well so far. There's no quantitative way to evaluate it air "purifying" ability, but I do notice the air isn't as stale. That said, other reviews I've read indicate that the machine is loud, which I tend to agree with based on the first unit that I bought. We actually didn't mind because the kids sleep with humidifiers on for the white noise. However, the fan on this is uneven, so rather than hearing a steady hum, it sounds a little choppy. I bought a second unit for another room and when I plugged it in, I thought it was DOA because I couldn't hear the fan on the low setting. The first one is definitely going back. Overall, this looks like it's a good unit and I'll eventually buy a 3rd for the last room. The only other downside is that you can't replace the UV bulb. see less

I have to say I was prett ... see more

I have to say I was pretty skeptical. The only reason I decided to do it was because I got a 100 dollar target gift card, so it took down the price quite a bit. That, and my and my husband were dying with the new found pollen bloom in San Diego this year (we never had allergies before this year). Anyhow, we can breath now, and it even collected some of the floating pet hair in the air. The proof was on the backside of the filter. It lasts 6 months before you have to switch it out, so it's economical. It has UV and Ion air cleaning abilities too (Kills floating bacteria and floating particles that otherwise would be missed by your average filter) I'd also like to say, you know how when the sun comes in through the window and it makes all the dust show in it's path? That doesn't happen anymore. I would say this is a very worth while purchase!!! see less

I have had this air purifier for 2 years and I am very pleased. I purchased it because it is one of the only air purifiers I could find that kills mold spores. The air smells clean and the machine creates a nice air circulation. I was hesitant about the costly replacement filters but I have not had to replace any so far and I've used the machine nightly for around 2 years. It is worth the cost knowing my family is breathing clean air. see less

We have 2 of these units ... see more

We have 2 of these units in black. We purchased our first unit about 5 years ago for our livingroom because I was concerned about air quality. We didn't use it much and I didn't think very highly of it. Then we had our daughter allergy tested and found out exactly HOW to use the unit correctly! The key is to NOT use the ionizer feature is you have someone that has allergy induced asthma since it will actually make it worse -according to our dr. We were also instructed to not change the HEPA filters, or remove and clean them, more than 1 time a year. The room that the air purifier is used in should remain completely CLOSED! No open windows to "let in the fresh air" - run the A/C in the summertime! Bedroom door closed unless you are actively walking through the door. This air purifier, along with the other changes made under the advisement of our dr, has done WONDERS for both our children! I just found out I have the same allergies and am about to purchase a 3rd unit for my bedroom! see less

My son has Asthma and a poor immune system and gets flus and colds easily. We have pets in the home and he had no allergies as he had been previously tested, but recently he has showed a slight allergy to a cat that is in our home now. So I immediatly went and got 2 of these air purifiers. His symptoms have gone away with daily vaccum cleaning and the purifiers on 24/7 in his room and living room. and my 2 relatives who are allergic to pets have had an easier time as well. Also my son has not gotten as sick as he usually does this time of year. Although, I do feel the motor is going out on one of them due to constant use and it can be loud on the higher settings. I will ALWAYS use this product as what this product has given our family far outweighs any cons. This is coming from a mom who has tried numerous similar products. see less

I moved into a dusty, probably moldy old house. I had bad allergies that led to a horrible sinus infection-- I didn't want a filter with an ionizer I couldn't turn off(who wants reduced lung function?) so this seemed like a good bet. I set the timer when we hit the sheets and my man and I both wake up clear-eyed and glad to be here. We can use the ionizer in the basement when no one is down there and let it kill everything. I like that the replacement filters are inexpensive, too. All the web research was worth it- I sleep better and cough so much less. see less

We registered for this air purifier for a wedding gift. We were excited to get it since we were combining houses....meaning I moved in and brought my dog. My husband has allergies and I was anxious to make sure the dog was not noticeable to him. We run the air purifier in the main room and it seems to work very effectively. Easy set up and operation. I like the "white noise" it puts out. It is a little louder on the higher settings than I anticipated but it's not a deal breaker. We're happy with it and feel like the HEPA filter is doing its job. We cook a lot and it seems to also help dissipate food odors from the nearby kitchen. I would recommend this product if you don't want to drop a large amount of money and you are dealing with an appropriate sized area. see less

Purchased this for a 1100 sqft apartment. Keeps the "hotel smell" at bay. Had a small dinner party on Friday night...by Saturday at lunch no lurking food or smoke odors. Works well. Only complaint is the 'free' filter deal...every time I have tried to redeem it I get the "Deal has been temporarily suspended...try again in 48 hours" and that's what I have gotten for two weeks. Still for less than [$] you can't beat it. see less

I purchased this Hepa Air Purifier yesterday. I have been looking at them for a while and this one seemed the most reasonable for the features it offered. We have two dogs, terrible allergies and an older remodeled home with a dirt basement, needless to say I noticed a difference in air quality within a day. The air seemed fresh and clean. The unit is fairly quiet and sounds like a fan. I would recommend this product. see less

My wife and I bought this after getting married. We live in a 800 soft condo with two cats and this has been awesome. Dust has been all but eliminated and it couldn't be simpler to use. see less

This is the real deal! I love the automatic setting... it will automatically go to a higher fan setting if it senses a smell or extra dust in the air. Settings 1 and 2 you can barely hear... setting 3 is a little more noisy but still fairly quiet compared to others. It's overall a great product and the proof is in the filter... as well as an improvment in my allergies! see less

My one warning, don't ge ... see more

My one warning, don't get this for a bedroom, it is too loud. Other than that, I love it, I am about to go buy a second one since it is on sale. I find it does a great job with filtering out odors, and is large enough to work as a fan for the room, so I save money on electricity, due to allergies, I can't use my ceiling fans. I've had my first one for 3 or 4 months, I go through air purifier filters in about 2 months for a 4 month filter, so by having re-usable filters, this purifier is saving me a great deal of money in replacement filters alone. see less

Honestly, I don't even care how this product cleans, though we have allergies and I'm hoping it proves to be helpful. I purchased it for the white noise! Neither of my two kids - 4 and 1 - can sleep through household or occasional outdoor noise. During the winter, a humidifier in each room was perfect to help muffle noise much better than any noise machine ever did. However, as summer approached, I haven't been able to find a fan that produces much sound at all - all are made to be "quiet." Since it's my small children's rooms, I didn't want a huge box fan or anything. The noise from this is perfect white noise, with a great selection on 3 speed settings (currently on high during nap time!). The noise isn't annoying and has no "hum" - just white noise which is PERFECT for the rooms of my small children. It's about the same as a humidifier. I am DELIGHTED. Holmes should market this to people looking for white noise for that purpose! see less

[...] The first day I bought it I read [...] about how loud it was. I was like "it can't possibly be that bad..." It truly is THAT bad, but it does the job. And I know me, I would never remember to go to the store and pick up a new filter, so this lifetime filter, also works for me. I ran it full blast the first day and turned it to low that night. It was downstairs and I was upstairs in my loft apt and I kept waking up bc the low speed was still way loud. So I turn it on during the day when I'm not there and turn it off at night. That works for me and I'm very pleased with the performance! I feel my air is cleaner! see less

I understand that a certain level of noise is to be expected with any air purifier but this is just ridiculous. I have purchased 2 of these Holmes air purifiers, and both have produced a very audible rattling sound when turned on any setting, it literally sounds like something is loose inside. I returned the first one thinking I had bad luck, only to find out that the replacement did the exact same thing! Sorry Holmes, but you have a long way to go with quality assurance and quality control. For what it's worth though, it does what it's intended to do, my room smells noticeably fresher when the unit is running. see less

I bought this product for my son's room who is a smoker. The permanent filter is not permanent. After absorbing smoke, the filter does need replacing. I contacted Holmes and they told me they do not sell replacement filters and it is not to be used by a heavy smoker. Plainly says tobacco in their advertisement. see less

I've owned the Alen A350 for only a couple weeks but so far it's doing a great job. There's 4 settings for speed - at 3 and 4 it it's loud but you use that for only a short time and then run on speed 1 or 2 to maintain the room. At 1 or 2 it's an unnoticeable background noise which is actually kind of nice when you're sleeping. I move it from room to room every few days, it's light and easy to carry. Filters seem very easy to change. Not sure if it's helped our allergies or not - we'll see come summer time. see less

I bought two of these units for my parents' home ... my mother suffers from asthma and my Dad is plagued with seasonal allergies. I placed one upstairs by their bedrooms - and one downstairs by the living room/kitchen - and the difference is remarkable. My mother says she even sleeps better and can breathe all the way in with one breath - while my Dad isn't a complete mess from his allergies to grass, pollen, and the great outdoors. Sure - the A350 cost a little more ... but my parents are worth it. : ) see less

Brief background:I have p ... see more

Brief background:I have purchased several air purifiers in the past (i suffer from medium severity allergies) and have not been satisfied with the results. Minimal relief at best.I had a friend recommend this brand of air purifier and I thought I would take a stab at this as I liked the look. Received the unit just fine, plugged it in and gave it my 7 day test. This is so i get working week and weekend usage out of it. I was definitely impressed as it definitely made a dent in my allergies. During the week (about the third day) I woke up and didnt have my normal foggy headedness or sneezing red eyes. I still had a little tightness in my chest, but I dont think any air purifier is a cure all.**something to note: I didnt see this in the description, but the thing has a lifetime warranty if I join their replacement filter program!!! not a bad deal, check out their website [...] for more details. last thing only real negative I have is that for the money i expected a better timer. is just a basic countdown timer, no way to set day and time at all. also some people might consider this too loud on the highest fan speed. Overall I would definitely recommend this to people who suffer from allergies. see less

As a COPD sufferer, air quality is critical. I started with 1 unit and within a few weeks, I went back and purchased 3 more units. I even placed 1 unit in the garage. What a difference....only wish I'd known about these several years ago. I strongly recommend these for those with Asthma / COPD / pneumonia / chronic bronchitis / Emphysema and other breathing disorders. see less

I have gotten this system to replace one I got at target store that was noisy. It is quite on low & mid you will not know it is there. But on high it is not that bad. The UV light gives off a odd oder at first but is some thing that looks that it works. Has taken out the smell out of my old home that I could never get away. This HEPA filter did it. I got another one for the other side of the house. see less

We received this purifier as a gift on Christmas 2010. My wife had recently quit smoking & suffered from frequent bronchial & sinus infections. We live in an older dusty house which didn't help. We had upgraded our whole-house filter to a higher MERV rating so I had reservations as to how much this unit would help. It works great and you wouldn't believe the amount trapped in the filter! My only complaint has been locating filters till I found a website carrying both our whole-house & this devices filter media at reasonable prices. see less

My husband had been practically begging for us to get an air purifier. I purchased this purifier at a steal for more than 75% off from Target. I couldn't pass up the opportunity or the deal. It is really quiet on low and medium. When it is on high you it reminds you of a fan blowing on high. I could definitely feel the air moving in the room about 30 seconds of turning it on. The replacement filters are inexpensive,especially when purchased in bulk. The manual states they should be replaced at max every 3 months. There is also a filter indicator that lets you know when it should be replaced.The unit is large but not an eye sore as compared to other filters. It's weird because I have it on now and I can feel the air moving but can't hear a thing. My family suffers from severe allergies so this was kind of a no-brainer. I would definitely recommend this unit. see less

I live in the California dust bowl. Yes, Bakersfield. Indoor air quality is dependent on what YOU make of it because opening a window for fresh air is out of the question. I bought this on a recommendation from a health provider. After evaluating ALL the pros and cons, this was my choice because of OVERALL use, effectiveness, maintenance. The filters are both permanent and washable . Static is stored in the filter and you will discharge it by touching. Does not hurt, but surprising. This product works. The air is lighter, you can feel stuffiness being removed on the first day. It is quiet. The unit is aesthetically well built. Even the ambient light has a pleasant glow to it has two settings of brightness. The air being given off is strong to even be "cooling" in the summer. If you are a germ-a-phobe , get one with UV. If you want a great air purifier that cleans the air including germs with no filters to buy, THIS IS YOUR UNIT. see less

The motor in this air pur ... see more

The motor in this air purifier turns on a ball bearing, this is a lot better than a standard fan motor, which turns on a lubricated hub. The electrostatic collecting filter is not made out of aluminum, which is what I had suspected, but it is made out of plastic, making it completely washable. I did not even know that plastic could be statically charged. The buttons on the top of the unit are all touch style buttons, except the power button, which is a press button. The bottom of the fan has an illuminated LED light strip which can be turned off. The fan motor has 5 speeds, of which the motor is stable on all 5 speeds, it does not start to make creeking noises on any of the higher levels. This air purifier is more efficient than a Hepa style of air purifier, that is because air freely flows through the electrostatically charged collecting grid, compared to a Hepa air purifier, in which air is forcefully pulled through a Hepa filter, requiring more power to operate. see less

Hands down it is a good product, well built and designed. My issue is that the ionizer is always on and creates a very very distinct smell. I wish that this feature could be turned off. I would say purchase it if you are okay with the ionizer type smell but avoid it if it irritates you. The product does a great job of reducing my place of allergens and reduced dust build up I've noticed. see less
