Good fit. Nice having filters delivered to house. Now the frustration of going to appliance stores resolved. No more disappointment of not having the filters I need. Thank you.

We’ve got these returns in the floor in this old house, with nothing to hold them. These 12x12 filters work perfectly.

I am very happy with
on June 25, 2026
Posted by: Customer
I am very happy with my filters. I needed an unusual size. I previously had to buy 3 smaller ones and duct tape them together every 3 months. Your filters came quickly, damage free, and is a much better quality. It took less than 30 seconds to change out and I noticed a difference in my air quality that same day. I bought a year's supply, so I will definitely be buying again next year!
