Review on CO Z HEPA Purifier Office Basement by Chris Elam

Bought because it was a discount. The first turned up with screws and everything else dangling inside ie filters, remote control, lightbulb etc which we didn't have. The second one still rattled but didn't look like screws so I installed it and powered it on. The fan runs at full speed very sporadically, so we did not see any improvement in air quality. Return and buy something with really positive reviews. Let the buyer be alert!
