This pleated filter is a MERV 8 filter efficiency. MERV, or Minimum Efficiency Reporting Value, indicates when a filter will be least efficient. So, the higher the MERV rating, the more efficient the filter. Most fiberglass spun filters, such as those found in your local grocery store, are usually only a MERV 1 or MERV 2. These filters are generally to used to protect the HVAC system in your home and do little to protect your family's indoor air quality. A pleated filter with a MERV rating of 7 to 13 is recommended to protect the air quality in your home. Clogged or dirty air filters can affect the efficiency and air flow of your heating and cooling system, causing it to work harder to produce the same air flow, while costing you more money!

These MERV 8 air filters efficiently reduce pollen, dust, pet dander, and other fibers from air in your home. Eliminating these airborne particles can help alleviate allergies and sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. An additional benefit of this HVAC air filter in your home will also extend the life of your heating and cooling system by making it work more efficiently.
These MERV 8 filters contain 14 pleats per linear foot which creates a greater surface area to catch airborne particles and decrease the airflow drag helping your system to operate more efficiently . The MERV 8 filter media is electrostatically charged and constructed with spun micro-fiber that also will not retain moisture, which can lead to microbial growth. These HVAC filters should be changed every 1 to 3 months for optimum performance.
