            Can never find this odd-size filter, so I was excited to locate them on your website. Delivery was very quick and they fit perfectly. Will definitely be buying here from now on, and highly recommend to anyone looking for sizes not usually stocked in stores.

            I purchase funrnace filters .The size I needed was not a common size you canpurchase at a big box store. Discoint ilters had the size I needed and at a great price. I recommend this company for all your filter needs.

                      It's so hard to find this size filter in local stores, so I was excited to find this website. I'm always a bit hesitant trying new sites and their products, but have to say I'm well pleased with my purchase. Good product, good price, and delivery was super fast.
                      Thanks!

                            Found these hard-to-find locally filters which turned out to be a bit cheaper and certainly more available than those I had found within a thirty-mile radius of home. They arrived promptly and are working very well for my purposes.
