MERV = 'Minimum Efficiency Reporting Value' this is used to rate the overall effectiveness of an Air Filter. Below you will find a table that measures the MERV strength and tells you the Application of each unit's effectiveness. In general an Air Filter with a higher MERV Rating is more effective and has a broader application, but most residential homes will find the best use from an air filter between the 5-12 MERV rating.

Reviewer: Sharon petrowski
With the help of customer service I was was able to replace my old furnace filter which had fork like plastic things to hold the filter in place with one unit that fits perfectly. It should last a year! Couldn't be happier that it fit

Reviewer: Edward Leonard
These filters are great. Dust way down in the house. Merv 8 is a nice balance of good air flow and maximum filter efficiency.
