    I have a purple air device monitoring my indoor air quality and this purifier has cleaned my air significantly. It is a bit loud when it's working hard (I keep it in auto mode) but it's white noise that's easy to ignore. After the first night it spent running on high, it's been very quiet and keeping the indoor air clean. I wake up feeling much better these days, so it's doing what I needed it for: removing allergens.

    I had this filter set so I could see the number of particles in the air. I placed it in my bird room where I have two African grey parrots. African Greys put off A LOT of dander and historically the things anywhere near my birds is always covered with a white powdery dust. I put this filter in the room and initially had it on High for a couple days. I looked at the screen and it said zero. What? How can it be zero, these birds and constantly losing dander. I was angry and ready to send this piece of junk back. But then, I checked the filter… COVERED in white powdery dust. My birds got spooked and flapped their wings, the reading on the filter turned red and jumped up to 116… then quickly right before my eyes it started to drop and the color changed to yellow, to green as the number dropped back down to zero. Wow, no wonder why it was always at zero… the air is clean!! Really clean!! Instead of sending it back, I’m going to buy another one. Amazing product and the absolute BEST filter I have ever encountered. If you need clean air, this is the one you want!
