Honest Price, Fast Service

If you are reading this you probably know these filters are NOT "20x25x5". The actual dimensions are a bit smaller. Therefore, this cannot be purchased at your neighborhood big box stores. This filter is OEM and the price is okay. Fast delivery, even with "standard" service. Happy with this company and will continue to buy my filters here.

Trust this company

I ordered the 2 pack of Merv #10 x6673 from for so very much less than if I were to have got them here in Denver. I received them within 3 days. Very happy and will not hesitate to use company again and again for my filter needs.
