The best air purifier deal out there is back. Perfect for fall flu, wild fires and even dirty pets.

I have been purchasing the Winix products when they go on sale all the way back to the c535 and have never been disappointed.

It's crazy that you get 2 years of filters and better room coverage than some of the super cheap products out there.

Check your local utility company for rebates! I got $50 x 2 for buying two of these since they're Energy Star rated.
this is the one everyone and their mama gets right?
Have this for almost 3 years, I don't have the Wifi issue people are referring to. I think a lot of those issues are related to the 2.4 GHz channel on their router. The only thing I found that s useful with the Wifi function is that I can turn on the unit remotely and set schedules. If you are going to leave it on all days or don't mind walk up to it to turn it on and off , you won't miss anything.

This product has alot of recent 1 star reviews. Been looking for a air purifier to replace my cheap box fan and furnace filter. Is this worth it?

Yes. I can't say it will filter much better than your box fan set up, but if you are in the same room with the box fan the Winix will be better.

Much quieter and everything is automated/remote.
If you are talking $50 air purifiers… those r crap and basically a box fan and filter in disguise

I have this one in the bedroom and the coway 1512hh in the living room by the kitchen. I say the coway is superior if you don't need WiFi, but I have it plugged into a smart outlet so I didn't have to give up that feature. The auto sense on the coway works way better than winix. Walmart does a deal with an extra filter occasionally and offers the filters pretty cheap especially when on sale.

Compared to a box fan, these type of air purifier can be more quiet, if you plan to put this in a location where noise can be an issue.

I now have 3 of these and love recommending them to people. It comes with 2 filters so essentially 1.5-2 years worth.

2 of these have failed on me but it was due to power surges, the warranty was seamless and replaced without much effort.

Highly recommmended.

Usually the same price in store without the shipping and handling if you are already going in

I was skeptical about this working, but there actually is less dust on surfaces every week when we dust now, actually worth it.
