Furnace Filter FAQs
Do I need to purchase the AirSafe frame?
Yes. What makes our filter system so unique is a combination of our hand made filter frame and the unique 3 stage filter media.
Are AirSafe filters MERV rated?
Yes. Our filter media is rated at a True MERV 6. What a true MERV 6 rating means is it will maintain that rating in your home. MERV rating by other manufacturers are done in a lab when the filter is sealed in a test cavity. Since other filters fit loosely in your return, there MERV rating is incorrect. Just having a 1mm gap around the cardboard filter frame can drop a MERV 15 filter to a MERV 14 and a 10mm gap reduces it to a MERV 8.
What is a MERV rating?
Minimum Efficiency Reporting Value. This standard was designed to rate overall effectiveness of air filters. Most think the higher MERV rating is better. Too high can actually slow air flow and damage HVAC equipment. Too low is not capturing dust and particles efficiently. The AirSafe Frame with the True MERV 6 filter is the best at both.
