Nice!
[This review was collected as part of a promotion.] This is such a great air purifier! It's all so it's easy to fit out of the way. It's simple to set up and easy to change the filter. It isn't silent, but the noise isn't loud at all and easy to ignore.

Small but mighty air purifier
[This review was collected as part of a promotion.] Love love love this air purifier! It’s not crazy big which makes it easy to move around the house or even take it when staying at friends or family, rentals or hotels! It’s has three air cleaning levels, auto off timer 2,4,8 hours, filter check , which you only have to replace once a year! Love the night mode it is so quiet! You can vacuum any large airborne particles that get captured from the base of the purifier. My husband is allergic to dust and we have a long haired cat and aside from the fur we see there is pet dander and so many more microscopic airborne allergens and particles we can’t see. We sleep so much better and just the peace of mind is awesome. Definitely recommend!

heavy duty hepa filtration in a small, lightweight
[This review was collected as part of a promotion.] i waited for allergy season to really be underway before posting this review and I can attest that this mini air purifier does a great job! it cleared the air and helped stop my sneezing. i positioned the air purifier on the floor, a desk and on a table - all were effective. designed for smaller spaces, this air purifier is so compact and lightweight it is easy to move around. one of the most impressive features is how silent it is - whisper quiet. the hepa filter only needs to be changed every 9-12 months, replacements are affordable and easy to install. this little machine deserves 5 stars.

Compact and very easy to setup.
[This review was collected as part of a promotion.] I received this product from Honeywell in exchange for my honest review. The setup on this air purifier was much better than I was expecting, and the power of this device was great. It offered multiple modes, which I could enable, such as timed mode, power, and night mode. The air in my room, I feel, is cleaner. The night mode is honestly my favorite part because I can still run it on a lower setting overnight. It is easy to take apart and clean, which is helpful. The size is also beneficial as I don’t have too much room in my room, and it fits perfectly on the end of my bed.

Works great and would recommend for an office.
[This review was collected as part of a promotion.] This is a perfect air purifier for a small room or office space. It does what it is intended to do. The filter is easy to change and makes a big difference with helping indoor allergies. The only thing I don’t like about it is the night feature. I like to sleep in a dark room and a fan. This is opposite. The light still stays on during night mode but the fan turns down to almost no noise at all. If you don’t mind the electronic light and quiet noise then this purifier is perfect for you. Other than that, I have no other negatives about it. The three setting and timer is a plus. Would recommend for an office but maybe not a bedroom.

Quiet power in a small package!
[This review was collected as part of a promotion.] I absolutely love this product! It’s very quiet, compact, and works amazingly well without taking up too much space. I use it daily and can really tell the difference in the air quality. One of my favorite features is the different settings and customization options. It has three different cleaning levels. You can choose a lower quieter setting for nighttime or turn it up when you want a deeper clean. The timer options are super convenient too. I also love that it helps reduce odors while capturing dust, pollen, and pet dander. Perfect for a bedroom, office, or small space.

Good purifier for small room
[This review was collected as part of a promotion.] Get jobs done, quiet on low speed, HEPA filter works for everyone with allergy , looks good at your interior, different colours shows air quality and 3 fan speeds, works bit noisy on the max . Size fits for nightstands.

Phenomenal!!
[This review was collected as part of a promotion.] Absolutely phenomenal product! We have tried several air purifiers and this one blows all of them out of the water. The nighttime whisper quiet mode is truly great if you're a light sleeper who can't handle noises. Other ones we have were almost like white noise machines, which can be good but this one is honestly whisper quiet. The video doesn't do it justice since I was right up on it but even the Normal modes are quieter than others. It seems very well made and great quality. It's super lightweight and easy to move around to different rooms. The timer mode is a nice feature also. We noticed a very noticeable difference in air quality after a few hours. Would definitely recommend!

Super practical for bedrooms or smaller areas
[This review was collected as part of a promotion.] Love this purifier! Super easy to set up and just with a quick click it's on its way to cleaning the air. The filters seem super thick and easy to replace as well. Can't wait to breathe better and reduce dust mites!

Compact and incredibly quiet
[This review was collected as part of a promotion.] This air purifier is whisper quiet, perfect for a small room! Compact, portable and has settings to time how long you want it on for. It is not heavy so you could easily move it from room to room, and seems to be built really solidly.

Small but mighty
[This review was collected as part of a promotion.] I really liked this air purifier for my home office/nail space. The highest setting sounds a little like a white noise machine but I kind of like that and it does have a sleep mode you can use. I have another larger air purifier that senses air quality and this small one seems to mitigate the fluctuation that usually happens when I cook or do nails and create dust.

Would Recommend, Has Helped My Allergies
[This review was collected as part of a promotion.] Tried out this Honeywell Allergen Plus Mini HEPA Air Purifier (HPA120B) for a few weeks. I am a big fan. I do believe it has helped my allergies tremendously, I am sneezing much less. Setup and operating it are easy peasy - basically pick a smallish sized area (I picked my bedroom, since I am in there for 8+ hours daily), plug in, and turn on. The indicator push button operation has lights for ease of use when setting the speed, timer, power, etc. Even on the highest setting, it's barely audible with my fan on. It's compact and lightweight-fits well on night stands, dressers, tables, etc. I haven't had to replace the filter yet, but the directions seem pretty easy to do that as well. All in all, I would definitely recommend it.

Quiet and effortless.
[This review was collected as part of a promotion.] Expensive, but works great. very quiet and easy to change out the filter. Room smells fresher and it is able to frequently clean entire rooms air. Covers the larger room than advertised with no issue. 100% recommend as an air filter for rooms.

Great product
[This review was collected as part of a promotion.] This "little guy" is a great thing. It's not very loud at all, I can sleep while it's on and be fine. I can tell the air is "cleaner" in my room. I'm sleeping much better and being told I'm not snoring that much.

Necessity for parents!
[This review was collected as part of a promotion.] The white color is chic and compact, which fits perfect in our bedroom space! I have a 1 year old and this keeps me from worrying about the air she breathes in our home. There is some noise but it’s the perfect white noise sound in our bedroom at night time. So easy to clean the filter and very user friendly!

I have noticed improvement in air quality
[This review was collected as part of a promotion.] I've been using this Honeywell mini air purifier for a few weeks now and I'm really enjoying it. I've definitely noticed an improvement in air quality and flow and it has a very pleasant sound that's calming at night. Setup was super easy and it came with a filter, it took me 5 seconds to get it turned on. It's small, simple to use, and can fit in many different areas in the room so I think that's a plus. Overall it just makes the room feel cleaner.

Great for small spaces
[This review was collected as part of a promotion.] The size of this air purifier is great for a small room, as it doesn’t take up much space. It easily fit on one of the nightstands in our room and doesn’t stand out. Easy to use and has several modes, including a night time option that makes it run quieter. Most of the time I don’t even realize it is on.

Compact, quiet, effective
[This review was collected as part of a promotion.] This is a great, lightweight air purifier for a small room. I’m using it for my baby’s room, which is right off the kitchen, and it has reduced the cooking smells that waft over. I like that it’s whisper quiet on setting 1. Other great features are that it has a HEPA filter that can last 90 days, and the unit overall has a 5-year warranty. Setting it up was so easy: just open up the base, pop in the filter (there’s no need to worry about which is the right side up - both side are the same), close it up and go. I do wish that this HPA120 series has an Auto mode; you’d have to buy the 125 series for that feature. But this is a great product in a compact package.

Purified
[This review was collected as part of a promotion.] This air purifier has been so great for my smaller rooms. It’s not bulky and fits in most places. It’s easy to clean the filter and the outside is easily wiped clean as well. The air flow is actually really good and I’m really glad I had the opportunity to try this out.
