  • This pleated filter is a MERV 13 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. A minimum of MERV 11 to MERV 13 filters are recommended for allergy suffers. Clogged or dirty air filters can affect the efficiency and airflow of your heating and cooling system, causing it to work harder to produce the same airflow while costing you more money!

    These MERV 13 Allergy Elite 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 13 filters contain pleats which creates a greater surface area to catch airborne particles and decrease the airflow drag helping your system to operate more efficiently. The MERV 13 filter media is electrostatically charged and constructed with 100% high-performance mechanical synthetic media 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.

    I have been a user of pleated AC filters for 24 years and the Atomic Filters are great as well as economical. I did notice the 20 X 20 X 1 are smaller by almost a half inch (19.5" compared to 19 15/16th" of the usual filters that I have used). This small Gap allows the filter to spring forward when the AC is not currently in operation. Atomic may want to add the extra width so that the filters stay in place at ALL times. The life of any AC unit is keeping the coils and corresponding parts Debris-Free of foreign particulates .. i.e. Dust, Grime, and environmental contaminants.

    The Atomic Filters are of Great Quality and perform Effectively. However, the small size creates issue with filters falling down in the filter housing when "Static Pressure" is released.
