What don't you like? Aprilaire filters do the job. We've been using the Aprilaire system for 12 years now and it really helps maintain air quality by returning the air conditioning. The older type had a plastic frame to which the filter was firmly attached. The new version has a reusable metal frame as shown in the picture. The filter opens like an accordion and slides into a rail on the frame. This purchase was for the filter portion only. See attached installation photos,
