I've been super happy with my Winnex and Coway. Pretty sure they are the ones that Wirecutter likes as well. The Levoits just don't seem to move much air. I like big, quiet fans that move lot's of air.

I've got a Blue Air 211+ and am pretty happy with it. I have extraordinarily bad seasonal allergies.

Well, I'm happy except the fact that the filters have gone up in price by 40% in the past year. I suspect this must be standard industry practice; launch a new purifier and price the filters at (near) cost. Once all the reviews have been written and the initial sales start to trail off, raise the filter price considerably.

Luckily there are knockoff filters.

I don't recommend Levoit.

I've had two of the very expensive ones die in the last year. Both the same kind of death where the software gets confused and it does not respond to any commands and won't boot.

Crazy that we live in an age where a fan+filter+sensor needs to boot an operating system.

While we are recommending filters, I absolutely love my Mila. Their best filter is about $100 and about once a year. I put the sock on there and clean that regularly and I suspect that makes the filter last a lot longer.
