This Air Purified has what it says. The Filter is 0.3 micron capacity which is cleanable with soft brush (NOT washable). Filter is made of Nylon cloth on outer facing and paper kind of material on inner side. Its hard to judge which side goes in and which one stays out unless you read arrow and follow. You can simply see Nylon material side says out. One thing I would like to tell is, filter leaves 1/8th space on sides which can be a space for air to go in. I had to work around to block that area with some gaskets so all air goes in from the filter only.
Function wise, only low speed is quite, medium generates low Sound which may be bearable while sleeping. High speed gives very good flow out but noisy. Causes noise equal to or little less than windows AC.
Good thing, it can be tit stand on a side and kept on floor to capture the dust. Most heavy dust particles remain on floor so this is usable that way unlike any other Product in market.
There is no digital functions or sensors or timers so I support it would not fail with any functions.
