What Our Customers Have to Say

Designed to fit into a typical 1inch return air grill. Fits like a glove, no air leaks around the filter. The extra depth increases the filter surface area and allows me to move up to a MERV 13 rating without significantly increasing the resistance of the filter. Although they are more expensive than the typical 1 inch filters, they last more than six months in my system. I have the technician measure the pressure drop across the filter during each of my twice annual tune ups to ensure I am not exceeding the system ratings. You can find that figure in your HVAC owners manual. I use two 20x20 filters in my return air side so I am a little over filtered and can go nearly 9 months between filter changes. A MERV 13 removes virtually all pollen and smoke particles.
