Great air filters.
However, I wish I could control the subscriptions online of when I receive them like I used to instead of having to email back and forth each time.

Not sure if it does anything
I guess I’m not sure how these work.
I have three cats and thought it would reduce dander. It just always says my air quality is great until I vigorously shake out blankets or my pillow. Otherwise it just says everything is great. I find that hard to believe. Not in a room with 3 cats sleeping on the bed all day.
Might be a waste of money.

Thank you very much for sharing your valuable feedback with us. We understand your concern that the unit is not effectively reducing the dander as expected. Please note that the unit is designed to capture only airborne particles that are as small as 0.1 microns. However, it is not capable of capturing particles that have already settled on surfaces or the ground. Thank you once again for taking the time to provide us with your thoughts.
