I live in a condo and the woman that lives below me is somewhat of a chain smoker. The smoke rises through the vents and electrical sockets. My old filter was doing nothing to help. After having installed the one AprilAire filter it has made a drastic difference. Maybe I've smelled her smoke once faintly in the past week. These will be my filters for as long as I live in this condo.

June 2026 was our fourth or fifth purchase from Discount Filters. The AC filters we've purchased are reasonably priced as well as having an advertised discount (email). Shipping has been excellent and on time. We will continue using them for our filter needs.
