I acquired two extra cats from my aunt when she passed away unexpectedly in July. My husband did not talk to me for a few days since I was essentially signing his death warrant. I bought this air purifier for our two bedroom apartment's living room and a cheaper one for the cat room. This machine has saved our family and the two orphaned cats. No allergic reactions so far.

Read reviews and decided to give it a try. Glad we did. It cleans the air and leaves everything feeling fresh. Loved this air purifier so much plan to buy another very soon.

I got this one particularly for cats room. I already own 2 Blueair purifiers for our bedrooms that I also got from Best Buy. Alen attracted me by the ability to customize the filter. I received the unit with HEPA filter that worked wonderfully until I decided to get OdorCell filter to combat my 2 kittens odors. No one can believe we have 2 kittens - our house smells so fresh. This unit looks very slick and modern, I won't call it silent, but it's not disturbing. I've tried to switch on Auto and noticed how fast and a bit loud it starts working at first until it clarifies the air. I usually run it on speed 2, and when my kittens are away from it, I run on Auto. Very simple to replace the filter and clean the unit. When I removed HEPA filter after 1 month of use, I've noticed a lot of cat hair stuck to the front - it shows how well it works cleaning the air from dust, dander, hair and allergens. OdorCell does the same, plus gets rid of all the bad smells. It covers large area as well, I believe slightly more than 1000 sq ft. We have open plan and it works well cleaning the air when I cook as well. Love it and highly recommend!!! I know, these brands are not cheap, but well worth. I've noticed, my daughter doesn't have severe seasonal allergic reactions anymore and house smells clean.

Have two BreatheSmart Air Purifier’s in different rooms of my home. I noticed different responses in both with the various changes of the environment. If cooking in the kitchen while auto is on the speed of the fan will pick up. In the bedroom while on auto the fan usually stays the same unless something changes the surroundings.

Got it for $120 off and it works great. Dust was a huge problem and now see very little. Allergies also a lot better. Can't recommend highly enough. Noise might be your only issue if running on MAX - doesn't bother me.
