Filterbuy filters have always been of good quality, good price, and have been shipped quickly. They have many sizes to choose from and I have used them for several years.

Only one question: why are the filters yellow on one side and light beige on the other. I have never seen a filter anything but white.

I had always bought my filters from a big box store. I saw these at a better price and they had excellent reviews. I bought a box and am already using them.

Some of the filters are no sealed to outer case all the way around them. Causing them to be useless.
