I really love this! I have asthma, two dogs, and my husband vapes a lot. This air purifier has so many features, and it even has a sleep mode. On sleep mode you can’t even hear the purifier running, which I think is great! There is an app you can download to not only operate the air purifier, but it provides you with stats on how many particles it is capturing from the air. The air in my home feels so much fresher since starting to use this. I’m not sure how to explain it but it feels less “muggy” and thick in here, and more clean and fresh.
