Frequently Asked Questions
How often should I change pleated filters in a dusty summer?
In dusty, dry summers change pleated MERV 8 filters every 30 days for the best protection. If dust load is light and the home has no pets or smokers, you may stretch to 60–90 days, but more frequent swaps protect HVAC components.
Will a MERV 8 pleated filter restrict my HVAC airflow?
MERV 8 pleated filters are designed to balance filtration and airflow. They usually allow normal airflow in residential systems, but if your system is older or marginal, monitor pressure and energy use; replacing dirty filters promptly prevents airflow restriction.
What if the filter's actual size is slightly different from the listed nominal size?
Small size variances are common—measure the filter housing and compare to the product's actual dimensions before buying. If dimensions differ, add a thin gasket or buy the next nominal size to avoid bypass and leakage.
