Winix 5500-2 Air Purifier w/ Carbon Filter $120.79 AC + Free Shipping on eBay sold by Best Buy. I believe this is the lowest it’s ever been. This has the washable carbon filter.

Winix 5500-2 Air Purifier
Saw a SD post on the Winix WAC6300 for $80 AC which is also an awesome deal. I figured it’s always good to mention alternatives. Although, this does not have the washable carbon filter.
Also, there’s a Crane Air purifier worth checking out for $80 AC.
