I bought this and it arrived last week. I bought it because I have cats and hoped it would help with the fur and dander. Well, I turned it on, and it's been on for a few days. It shows blue, which is good. I just finished cleaning the cat litter, came back in and looked at it and it was showing up red, meaning there were a lot of particles floating around. I turned up the fan, and it took almost 15 minutes for the air to clear. This means that we were breathing all that dust in previously and now we're not. This is fantastic. Less dust, less sneezing. Happy joy.

I have a small home, under 1000 square feet. I have pet birds and a cat. Because I was still getting some bird dander in the main house, I decided move the unit into the birds room. While I was cleaning in there, the unit was working great to filter the air! High hopes that it will keep the dander down. I had another brand purifier in there, but didn't cut it.

Its very dusty where we live, and our 3 large dogs torture our house, so we installed a HEPA14 filter on our HVAC system. It helped but we still had stuff floating in the sunlight. And our sinuses were still whacked.

So we bought a Reg & Mini bundle. The mini is in our mstr bedroom, and the Reg is in the family room. What a difference! And then the wild fires smoke came. And in our 2400 sq ft ranch they struggled. So we bought a dbl Mini bundle. Dang! No more smoke or dog dust. Even bacon smells disappear. And sinus issues are 95% gone.

But I was stunned when I replaced the filters! So. Much. Dirt!
