If you have ever shopped for a new air filter for your home, you have seen the variety of types available. In fact, we covered these in a blog post last month titled, A Home Air Filter Buying Guide for Your HVAC System.
But even among filters of the same type, there can be a wide variance of quality and efficiency. For that reason, the MERV rating was developed.
MERV stands for Minimum Efficiency Reporting Value. It is a measure of the efficiency of the air filter (the amount of airborne pollutants it removes). The MERV rating helps you determine which air filter you should use for your home air filter.
In general, air filters with higher MERV ratings remove a higher percentage of airborne contaminants, therefore improving your home’s indoor air quality. But does that mean you should just get the air filter with the highest MERV rating? Not necessarily.
No. It will depend greatly on your heating and cooling system and your home’s size. You must strike a balance between removing the most airborne contaminants while still maintaining adequate airflow.
