I have 4 dogs, 3 cats, and live on a busy residential corner. I have been fighting dust and fine dirt for 3 years. I already see the difference! The sunlight coming through the windows is no longer full of dust particles. I just feel that the air is fresher and cleaner to breathe. I keep mine on auto and every once in awhile it goes into a higher fan mode when it detects more particles. I have one in the bedroom and the other on the living room. So far so good. Thank you for making a product that actually works as expected.

These two make 4 in my house. Kitchen, bedroom, living room and cat room. Small house, 7 furry housemates, these do help. I can tell a difference in the air. I run a couple of them wide open a good amount of time. Also love it for white noise in the bedroom. I really like the dark greenish color for the living room.

I Love ❤️ Sans. When my husband cooks some things I turn on the purifier and it takes the smell out of the house. I can smell clean air. Great for the family while watching tv. I forgot to register my sans air purifier don’t do what I did just register. I’ve had the purifier for probably about two weeks.

I've had my Sans Air Purifier now for about 4 months, with 1 air filter replacement. When I changed the filter, I was surprised to see how dirty it was. But then again, I had been noticing how my nasal passages seemed to be so much clearer. I'm glad to see all the impurities in the air captured in my Sans. Cheers to fresh and clean air!
