ENERGY SAVING: Pleated for increased particle holding capacity and airflow efficiency. By decreasing the airflow drag your system operates more efficiently

SYSTEM PROTECTION: Keeps HVAC coils free of dust and allows them to operate at optimal efficiency. Filters should be changed every 1 to 3 months

Performance Data of this MERV 13 filter is initial resistance of this of 0.26 in (w.g.) and has a rated velocity(FPM) of 300.

What MERV should I get for air filter? According to the EPA, upgrading from a low-efficiency fiberglass filter to a medium-efficiency filter (MERV 5–8) can significantly improve the air quality in a home. Higher-efficiency filters (MERV 9–12) will work even better, and a true high-efficiency filter (MERV 13–16) can remove as much as 95% of the particles that pass through it.

Will MERV 13 damage my HVAC? It depends on the resistance of the filter which can vary by brand. According to the EPA "Most furnaces and HVAC systems can accommodate a MERV 13 filter without creating equipment problems, provided that the filter is replaced frequently." You should check with your HVAC contractor if you have an older system or are unsure. Better quality filters will have a lower resistance for the same MERV efficiency.

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.

These MERV 13 Allergy Elite air filters are the best to 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 a pleated HVAC air filter in your home can also help ensure proper airflow.

Is a MERV 11 or MERV 13 filter too restrictive? In General, Modern HVAC systems that have been properly designed and sized for the home are designed to handle MERV 8 to 13 air filters that will help protect air quality in the home. If you have an older system or it has not been properly sized check with an HVAC contractor that understands air quality. If they dismiss a high MERV filter without asking about performance data on the filter, you may want to check with another HVAC contractor.

These MERV 13 filters contain pleats that create 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.

Atomic's Ultra Premium(Best) Filter Superior Level of home air filter or furnace filter which is a MERV 13 filter, that provides Tremendous efficiency at an extraordinary value.
