Runs quietly, 3 speeds, works as described

I love that this runs quietly, has three speeds, and works as described, however there is no automatic shut off feature and they do not make it easy to find out which replacement filters you need or how much they cost

Helped in-law move into new house, air was stale/funky, we ran it and it cleared the smell out completely

Very nice little air purifier

I have had a few of these binary air purifiers. Now have them set up in several rooms and has made a notable difference. Note when buying that do you have to increase the square footage compared to what they say is enough, making air purifiers more expensive than they appear. It depends on how many times per hour you want the air to exchange.
