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.

Grateful I found this size at Discount Filters and at a resonably good price. Much better than ordering on Amazon. Shipped quickly.
