What is MERV 13? 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 is at removing smaller particles from the air stream each time the air passes through the filter.

Most fiberglass spun filters, such as those found in your local grocery store, are usually only a MERV 1 or MERV 4. Those lower MERV filters are designed to protect the HVAC equipment but not for Air Quality. 

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. 

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.

Do MERV 13 filters reduce air flow? It depends on the manufacturer. Not all MERV 13 filters will have the same resistance from one manufacturer to the next. If you are comparing a MERV 8 vs MERV 11 vs MERV 13 from the same manufacturer, the resistance will generally increase as the MERV increases.  Some manufacturers have significantly lower resistances on High MERV filters compared to other manufacturers. 

Is MERV 13 too much for a house? It depends on the HVAC system and the resistance of the filter. The resistance of the filter can vary from one manufacturer to another. For example, homes have up to MERV 16 air filters with lower resistances than MERV 13 filters of another manufacturer. If you are unsure check with your HVAC contractor and tell them the initial resistance of the filter you are interested in purchasing. 

How Can a MERV 13 Filter help an Allergies Suffer? MERV 13 air filters can 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. 
These MERV 13 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 13 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.
