I am very pleased with the Filterbuy a/c filters that I recently purchased. The air quality in our home has improved and with the MERV 13 filtering capability more particulate matter is being removed from circulating air!

The size selection and filter rating provided everything I needed, and the shipment was very fast. I'm good for awhile, thank you.

You barely took an allowance from the width and length in turn I had to cut it down to fit into the receptacle. Will not be reordering
