These MERV 13 13x21x1 (Actual Size) Sized Air Filters are available in a MERV 13 rating. 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. It should be noted that most fiberlgass spun filters such as those found in your local grocery store are usually only a MERV 1 or MERV 2. This can affect the efficiency and air flow of your heating and cooling system, causing it to work harder to produce the same air flow and costing you more money!
MERV 13 Air Filters effectively reduce pollen, dust, pet dander, mold spores, dust mites and other allergens from your indoor air. Removing these airborne particles can help improve allergies and alleviate sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. Aside from the health benefits having a MERV 13 Air Filter in your home will also extend the life of your heating and cooling system by making it work more efficiently.
