So far satisfactory

Haven’t had them long enough for an evaluation but they are better quality than what I have previously bought and are a tighter fit. I’m sure I’ll give better review after further evaluation!

These are well built filters, they come right to your door so you don’t forget to change them or have to go to the store to find them.

The Best!

I'm so glad I found Filterbuy, I've always had trouble finding this size filter, but this site has them all and it's so convenient. I received an alert on my phone and ordered on our way out of town. These are great quality filters and reasonably priced, I ordered enough for the whole year!

Good filter but could use small improvements
on November 3, 2026
Posted by: Customer
The product was received slightly bent but still usable. I have visible evidence the filter is working by the amount of particles on the old filter. I do wish the size would be closer to the advertised size. I have to use small pieces of cardboard to eliminate a whistle from an air gap.
