Q: Approximately how long does the HEPA filter last before it needs to be replaced?

submitted by Donna - 8 years ago

  • A: If the unit is run 24/7 and you clean the charcoal filter once a month you should get 6-8 months out of the filter.

Q: The info references California Prop for toxic/cancer causing chemicals. What is the ingredient/concern with this filter regarding that Prop?

submitted by dianna - 6 years ago

  • A: I read it is the titanium dioxide

    submitted bySarah - 6 years ago

  • A: The warning is pertaining to the internal components of the power cord. The internals of the cord can potentially have lead or lead compound. If in the event the cord is damaged and you have exposed wiring, you could then potentially be exposed to lead or lead compounds and you would want to carefully dispose of the unit with a towel or gloves.

Q: How does the UVC light even work were its positioned ? its fully enclosed and above the air flow and filter, unlike the 5000 models the light is the entire length of filter and entire off the air flow

submitted by tom l - 3 years ago

  • A: Hi, it does not matter where the UVC light is, because UVC light technology is a radiation method that make use of a specific wavelength of ultraviolet light to neutralize microorganisms. UV-C light is germicidal which means it deactivated the DNA of microorganisms like bacteria and viruses disrupting their ability to multiply. Have a great day!

    the fan is now extremely loud. I have checked if it is a filter issue. It's not. And as I am not about to takte it apart to fix the fan on a pretty new item, I will be returning this. Unaaceptable for such an expensive an important item.

    Caution blue light

    The air flow quality is very bad and the light doesn’t purify anything because of the location I do not recommend this product and smaller than what I thought it would be from online.

    Aif Filter good, Customer Service in Gastonia store- EXCELLENT

    We have guinea pigs and my old air filter broke. This was our replacement. It is much quieter than our old one (Honeywell.) However 4 starst because the replacement filters are costly (when the time comes.) I got this on-sale and so it was affordable to start with. I give customer service at Target 10 stars though - they were excellent. The original filter I purchased in the store was obviously opened and returned and reshelved - it was defective. I brought the filter in to exhcange and there were none left - customer service helped me navigate ordering online while still honoring the discount I had received when the sale was going on (sale had since ended) - and they were very efficient and kind. I really appreciate them helping me out. Gastonia NC store- customer service front desk - amazing!

    Confused & Dissapointed

    I feel bad writing this review, but I have to let my experience w/this filter out to all--who knows maybe someone also has experienced the same. I have no complaints about the noice, the blue light but the BIG ISSUE is that my allergies, which were mild before have completely increased, to the point where I had to go my doctor. Watery & itchy eyes, sneezing, coughing, etc. were killing me!! Mind you, this was all during the first week of purchase, although I still did not give up on this, thinking the absolute increase of these allergies were brought on by something else, but no it was no doubt this purifier. Overall it had good reviews, so I didn't mind spending over $100 for something that worked!! Now I have to spend more time, extremely inconvenience to return this--there's no chance I can keep this. I mean come on, I had to take prescribed medications from the result of this filter, that's why I'm confused. Worked so well for others but I was in hell :( Also, it's not like I've never had one, but the result was no way close to this one. >>NOW TO START AN INCONVNIENT RETURN OF THIS PRODUCT W/OUT ANY COMPENSATION. Sad. I chose to give ZERO STARS for its value

    Air purifier

    after hearing friends say they have less dust in their homes and less sinus problems and coughing, I decided to try one. I am noticing a reduction of dust on flat surfaces so that is a good start. I live in an agricultural area so it gets bad. I move it to the bedroom at night but will likely buy a couple more units.

    It works so well and I’ve noticed my allergy symptoms are better. Plus I have a cat and it’s helped a lot with that too. Loook at the difference of the old filter vs when I replaced it! It collects so much dust . I’ve had it for several years
