MERV rating or, Minimum Efficiency Reporting Value, is a measurement scale used to report the effectiveness of an air filter at capturing particles of a certain size. The higher the MERV number, the more efficient the air filter is at filtering particles of a known size.

A MERV 13 filter, for instance, is capable of filtering out particles as small as 0.3 microns in diameter. In comparison to a MERV 8 rated filter which is only capable of filtering out particles as small as 3.0 microns in diameter.

Before purchasing and installing a high-efficiency filter it is first important to check the maximum MERV rating of your HVAC system. Higher MERV rated filters reduce air flow to the system which may cause damage or force the HVAC system to shut down.

It's easy! Follow the step by step instructions below. For reference, the back (wired) side of the filter should be facing into the slot, with the front (pleated) side of the filter should face you.

The filters we make are deisgned for up to 3 months of use in an ordinary household environment. However, filter life can be shortened by individual conditions (like how many pets you own or if you're painting). For that reason, you should routinely monitor your filter to determine when it should be replaced. Continued use of a filter that should be replaced may restrict air flow and impair the efficiency of your heating/air conditioning system.
