Frequently Asked Questions
Will a higher MERV rating restrict my HVAC airflow?
Higher MERV filters can restrict airflow if they are denser in a 1" package, but many modern MERV 13 designs use deeper pleats or 2" thickness to preserve airflow. Confirm your HVAC system’s filter depth and static pressure limits before upgrading; when in doubt consult an HVAC pro.
How often should I replace these pleated electrostatic filters?
A common schedule is every 60–90 days for typical homes. Replace sooner if you have pets, smokers, recent construction, or during heavy pollen or wildfire events. Check the filter visually — a dark, loaded face means it’s time to swap it out.
What size should I buy — nominal or actual dimensions?
Buy for the slot size specified by your system but check the product’s actual listed dimensions. Several customers report small differences between nominal and actual sizes; a slightly undersized filter can allow bypass while a too-large filter won’t fit.
