Filters did not take long to produce, as I purchased a special size not readily available. Filters are high quality and work perfectly, will order again and recommend!

HVAV works better now. Filter fits like a glove. Heating is a lot better since we changed it and they auto ship so you wont forget to change every 3-4 months.

When I receive the filter I was surprised to see that it was not the full size as listed in the website large print. I went back to the website and review the dimensions. This is what I found.In large print:20x25x4 Air Filter DescriptionBelow that in smaller print:Actual Size: 19 3/8" x 24 3/8" x 3 5/8" The original flex filter that it replaced actual size was 20x25x4. It also has double the number of pleats of the Filterbuy filter. I am concerned about air bypassing the filter with air leaking around the edges of the filter because of its smaller size.
