Winix C545 (refurbished) 4 stage WiFi smart air purifier $70 on Woot!
Normally the new one sells for $130 on Costco.com with an extra filter, and on sale it’s $100 (see front page deal from 9/21)
This is an opportunity to get it for cheaper, though it’s a refurb, and no extra filters.
I have 4 of them and they’re great.
