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 5-13 MERV rating.

Effectively meet my filter needs
I have been using this filter for years. When I change the filter, it is clear it's filtering dust and doing the job well. I will continue to use it.
My second time ordering these filters and I'm very pleased.
excellent product.
Great product. Best filter I've ever used. It's amazing how much dirty air in our home and this filter does its job. We change every 4 months.
