I’ve been searching for an air purifier since 2020. The pandemic made me think about air quality so much more than I ever have. This is a great model it’s not big it actually fits on my nightstand table and can be used in just about any room. I have moved it around. The digital readout is extremely informative it tells you what types of particles it’s picking up and how much time remains for the air to be as clean as it can get it. The fan is not loud and it’s actually pretty comforting to sleep with- white noise. smells from dinner or perfumes and such are diminished by this machine. It’s a winner!
