Lets put it along these lines. Its not an air purifier but rather an air disinfectant. On the off chance that you are searching for an air purifier to wipe out dust particles, smoke and suspended particles noticeable all around, this is not the one for you.
It scarcely has a bit of material such as channel which does nothing to refine air and is incapable. In any case, yes since it produces ozone gas it can purify air borne infection/microbes. What’s more, given its little size it can scarcely cover a match box size room. Purchase this just on the off chance that you need to sterilize air. Pick carefully!
