The FiltersFast 4-inch MERV 8 Air Filters, 3-pack have a MERV 8 rating and can be used in a variety of applications including residential and commercial. 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 fiberglass 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!

FiltersFast Air Filters MERV 8 effectively reduce pollen, dust, pet dander 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, quality air conditioning filters will also extend the life of your heating and cooling system by making it work more efficiently

FiltersFast Air Filters are an economical alternative if you're looking for a quality air filter without paying a premium price!

FiltersFast four inch air filters contain 8 pleats per linear foot which creates a greater surface area to catch airborne particles. These air filters should be changed every 3 months for optimum performance.
