Did nothing but make noise
Put in a small room that contained a litter box and this did nothing. The noise wasn’t bad initially, just a low fan noise like a computer. After a few days it starting making a low squealing noise and got very annoying. Since it wasn’t doing anything for the air I just unplugged it and returned.<br /><br />Disappointed this didn’t work for me. I have a large germguardian purifier that I love, so I like the brand but not these particular products.
