OK Filter Co.

We manufacture a wide selection of HVAC filters in many different efficiency ratings. Located in Tulsa, OK, we're one of the leading manufacturers and sellers of premium air filters for residential and commercial spaces. Initially named A-OK Filter, our company was founded in 1969 as a filter distributor, selling and marketing for different manufacturers. Fifteen years hence, we began manufacturing our own line of air filters. In case a product gets damaged before you receive it, we have a proper return policy in place to solve such issues with minimum hassle. We offer a wide range of Merv rated filters. MERV is the primary international air conditioner furnace filter industry standard and is used for rating the ability of a furnace filter to capture and hold particles and pollutants. The measurement used in these ratings is a Micrometer, or micron.
