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

Perfect small space air purifier

I found this online at a great price with good reviews and I had been looking at more expensive air purifiers. Needed something to put near my cat's litter box to keep the smell from over taking my home. I've had it running almost a month and I have it about 3 feet away from my cat's litter box and it works exactly how I need it to. I have not had to replace the filter yet so I don't know how long that will last. It does make some noise if it's at level 3, there are 3 settings but it does not disrupt my day to day. Over all I haven't had any problems so I'd say this was a win win!
