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.

Great product, great service

Love the option to set up recurring orders (and modify as needed). Would prefer a lighter color (easier to see when they are getting grungy) but overall great product.
