Frequently Asked Questions
How often should I replace a MERV 8 pleated filter during spring?
Replace every 60–90 days during high pollen season, or more often if you have pets, heavy dust, or allergies. Check the filter monthly—if it looks clogged or discolored, swap it sooner.
Will a MERV 8 filter reduce my HVAC efficiency?
MERV 8 filters are designed to balance particle capture and airflow. When properly sized and changed on schedule they should not significantly reduce system efficiency. Avoid using higher-MERV filters than your system can handle without consulting an HVAC pro.
How do I make sure the filter fits my furnace?
Measure the slot opening and compare to the product's actual size (not the nominal size). The listings here provide the actual dimensions—confirm thickness and length/width before ordering to prevent fit and leakage issues.
