We have been using these filters for a year and they are wonderful. Such a cost savings too. Super fast ship and the subscription program makes sure I don't run out!

Finally a 4 inch pleated filter at a price we all can afford. Great quality and even better price.

I'm very satisfied on my online purchase. It was easy to find the correct filter for my needs and convenient to set up an auto-shipment plan.

The filters seem fine, but why cant I get a true 16x25x4? We arent buying lumber here. Can go to the hardware store and get a true to size filter, but cannot find a nominally sized filter on the website. I dont get it.

Good Enough

The depth is not exactly to size so it fits kind of loose and the materials looks cheap. But house smells fresh and no visible dust particles. Can't remark to the MERV rating yet though.

I purchased two 20x20x4 filters from another company months ago. They were actually 20x20x4 inches in size. Too big to fit in in my hvac. The Filterbuy filters were sized a smigen smaller and fit perfectly. They listed the size on their website so I knew they would fit. I will buy filters from NO ONE ELSE. Great company great product.
