Understanding Air Filters: Know Which MERV Filter Will Work Best With Your HVAC System

According to the Environmental Protection Agency, indoor pollutants are among the top five health risks found in American homes. The correct air filter will help reduce the amount of pollen and dust in your home’s air. MERV (minimum efficiency reporting value) is gauged by the size of particulate matter removed by the filter. The higher the MERV rating, the smaller the particulates removed. While you may think an air filter with a high MERV may be the solution, this may not be the case. Your home’s HVAC system needs adequate air flow to perform efficiently.  Your HVAC contractor will know what type of MERV filter your system will handle.Understanding Air Filters: Know Which MERV Filter Will Work Best With Your HVAC System

Air filters work by removing pollen, dust and debris from the air before it reaches your HVAC’s system. The majority of air filters used in Amarillo homes use a mechanical method for removing this particulate matter from your home’s air. Air passes through the filter and the particulate matter is trapped on the fabric of the filter. When the filter becomes dirty, it is removed and replaced with a new filter.   When to change the filter is determined by the recommendation for the filter and your personal observation.

Typical air filters used in residential service have a MERV rating of between one and 13. High efficiency filters have a MERV rating of 14 and above. Your HVAC contractor can help you decide which filter will work best with your system so as not to restrict the air flow.  If your HVAC system can’t get enough air flow your energy costs will go up, and your system will struggle to perform. (The restricted air flow can also happen with a dirty air filter.)  This can lead to costly repairs down the road.
