I needed a new filter for my furnace, and the local big box stores and local hardware stores did not have my size. I looked on line and FilterBuy' s responses were quick and all was accomplished.

Shipped fast, waiting to see how they perform after a few months.
First time using this brand, so need to wait and see how it works.

Great filters

I’ve been subscribed for several years now and find their service very good. One time I received a lower rated filter by mistake and they expedited the correct filter at no charge and giving me the other filter. I chose to donate it from their suggestion. Really cool

Inconsistent Sizing

Previous filters worked fine, but the last purchase, and the one before that, are loose in the width and too long in the length.
