Very quiet and seems to work well! I have a 65 lb. dog and 2’cats! They all shed and it helps with the dander and dust which annoy my allergies! This is helping me! Good quality for the price!
Really like this purifier. App is easy to use and makes us feel safe! I like how it shows both the indoor and outdoor air quality and gives details on what toxins to be aware of. Much better than my other air purifiers
