I used to wake up with mild allergy symptoms (now I'm allergic to dust mites and carpet). Ever since I bought this air purifier I wake up with no allergy symptoms. I haven't really measured how well it cleans, but the lack of allergy symptoms seems like a pretty good indication of what it's doing. I just leave it on Auto, which means it runs on the lowest settings most of the time, which is completely silent. The connection dropped a couple of times at the beginning but since then it seems to be working pretty well so I can manage it through the app but since then it's only been working automatically. I don't use this feature very often (almost never). The only missing feature is the ability to set a schedule (e.g. start on setting 3 from 17:00 to 18:00, otherwise automatic). I don't really need it, but I see it might be useful for some people. It has a sleep function, but it's not the same (you can't program sleep in advance and it just turns off at the end of sleep).
