Not so “mini” but works great! My husband has a whole bunch of issues with sinuses, breathing, allergies and we wanted to give a purifier a shot to see if it makes any difference. He says he wakes up not feeling so congested and loves it so far.  It’s pretty quiet on the lowest setting and no issue running when the kids are asleep. Quite a bit louder on high. Just make sure you read the dimensions. It must be a lot smaller than the full size, but it’s still pretty big. Or maybe because it’s meant for smaller rooms. Anyway, we are happy that it’s serving its purpose!
