Might clear the air, but makes noise!
I purchased a 2 pack in late June 2022.  Right out of the box we plugged it in and the light came on and you can hear the fan spinning, actually kind of loud, but depending on the area used, it might be ok.  I wouldn't recommend it in a bedroom.  Well, here it is August 2022 and the fan noise had stopped.  Light still on.  I opened it up and found the fan no longer spins.  Is it still working???  Doubt it.<br />**Edit**<br />I contacted the company about the issue, they found it was still covered under warranty and sent a new replacement within 3 days.  This one runs much quieter than the one I had an issue with, so updating to 5 stars.<br />*****
