Quality, Selection and Price

I’ve been using FilterBuy for a long time. I find their products to be of equal or higher quality than most major brands. They do not try to up-sale products, they give you the choices, inform you of the differences and let you make the choice. I can’t even remember the last time I purchased anything else, it doesn’t make sense.
Simple and strait forward.

A little smaller than the advertised 16x20. Makes it easier to install.

Cancellation was submitted years ago. Now it seems that your sales department owes you answers to how I am still on this subscription

Fitment is poor.
on November 3, 2026

Size is about 1” off on both sides.
Measurements should be much better than that.
Price was good and filter still works but have to wonder if it might be bypassing slightly.
Not impressed based on first impression.

Pleasantly surprised
on November 2, 2026

I waited a while to use the new filters since I had just replaced them. I didn’t even open the box. I did the filter change today and opened the box and was pleasantly surprised by how sturdy and well constructed the filters were. I’ll tell you more about their performance when my next filter change comes up.
