Fresh air, fresh start

I’m impressed with the wide selection of filters on your site. This particular filter is nowhere near me as I shopped around locally. I am happy to purchase it from you. It is also a plus and is great service to have the opportunity to be on an automatic filter change program.
I would recommend it to anyone!

Quality filters at a good price. 4 pack on auto renewal keeps it simple.

Great filter for competitive price. Fit was the exact size as advertised, unlike competitors.

Wrong size 4x20x25

Quick service but the actual dimensions are wrong. The fit was incorrect, too small. Had to stop service and go back to the big box store filters.

Good Filter just is not 20x20x4
on April 28, 2026

Purchased these filters to replace the original Honeywell filters and these are significantly smaller. They are not close to 20x20x4. They just flop around in the filter tray. These will not work for my application.
