Review on 🌬️ Ivation 5-in-1 HEPA Air Purifier & Ozone Generator with Timer and Remote, Ionizer & Deodorizer - Cleans 3,700 Sq/Ft - HEPA, Carbon, Photocatalytic Filters, UV Light, Negative Ion Generator by Jennifer Johnson

The air purifier/ozonator worked surprisingly well for just over a month. When I turned it on one day, the ozone part didn't work at all. I cleaned it, changed the filters, changed the fuse, changed the ozone plates - nothing solved the problem. Unfortunately it's been 2 weeks since the return period so I basically have a $150 fan and can't afford a replacement. Don't buy any of these unless you have the money to replace them in a month or so. Even if you buy an extended warranty from Revain, it's probably still not worth it if you have to send it back every few months.
