GermGuardian Air Purifier with HEPA 13 Filter, for Home, Bedroom, Allergies, Pet Hair, Removes 99.97% of Pollutants, Covers Large Room up to 740 Sq. Foot Room in 1 Hr, 22", Gray, AC4820

Fabulous product for price point and size. I bought two; one for my bedroom and one for my office at work where the building has ventilation and mold issues. I leave them running 24/7 in both locations and my allergies, both nasal and skin have significantly improved. The lowest setting is a whisper, the second a bit noticeable but won’t wake/keep awake a light sleeper like myself, the third is noticeable but oddly soothing. The breeze output of fresh air is relative to the speed you choose. As an added bonus to getting serious relief from allergies, it purifies the putrid air that escapes my husband’s backside as he deeply sleeps when he has food that is too rich quite quickly, which means fewer middle of the night incidents of “*#?!” from me when I wake up gagging.

Well made, super quiet, compact and it really cleans up the air! It’s great that you don’t have to buy filters for it- the filter is washable.

I've had this product a little over a month. It has been an overall good value and works just as advertised. If you're in the market for a small-town (up to 160sqft) this is a quality product that you may want to consider purchasing. I am quite happy with mine. On another note, I emailed asking if this model's filter was interchangeable with model 4825 and they replied in less than 24 hours and maybe even less then 12! Now that's the kind of service and response time I expect as a consumer.

Seems to work well. My pet has had no allergy related asthma attacks since purchase. Works very quietly but still makes some sounds on 3.

LOVE IT!!!! I’m not kidding I really love it!!! I’m allergic to cats and two months ago I reluctantly took in a stray cat. I thought I was going to be miserable but honestly I have tolerated this cat in our home very well. Because I’m allergic I can’t be touching the cat very much. But this air purifier absolutely makes it completely tolerable to have this cat in our house. and I have asthma..... I completely swear by this product!!!! It cleans the air of dander so well. I did my research on best air purifiers for homes with pets. I read hundreds of reviews before I made my choice.

This is my 4th purchase of a Germ Guardian Air Filter. This one does not have the blue sanitizer light but it's still a great little cleaner. We have 2 cats and a hound dog. Both my husband and I are technically allergic to cats and dogs but with 4 of these running in various places in our home we have been able to live comfortably with pets. I also used to need a daily inhaler to control my asthma and now that we run these 24/7 I have found that I am needing my inhaler less and my doctor is considering just prescribing me rescue inhalers. I can't believe how much our air quality and breathing has improved with these! I have the filters on auto-ship with Amazon. If you clean the pre-filter regularly, the main filter should last about 6 months.

Cleans the air from mold and allergens. This product is a workhorse. I have it running 24/7. Since using I rarely get sick. Totally worth it.

Excellent product! I will definitely buy this again.
