Frequently Asked Questions
Will a MERV 8 pleated filter reduce my HVAC airflow?
MERV 8 pleated filters are designed to capture common particulates while maintaining healthy airflow in most residential systems. If your system is older or already undersized, choose a 1" MERV 8 or a 2" option with more media volume rather than increasing to a much higher MERV, which can restrict airflow.
How often should I replace pleated furnace filters?
Replace typical MERV 8 pleated filters every 60–90 days under normal household conditions. If you have pets, allergies, or heavier dust loads, check monthly and replace sooner. Thicker 2" filters often go longer between changes because they hold more dust.
What should I do if the filter seems slightly smaller than the slot?
Many filters list an 'actual size' slightly smaller than the nominal size to ensure they slide into varied housings. If you see a noticeable gap, consider using a slightly larger size if available or add a thin gasket to reduce edge bypass. Always avoid compressing the filter media, which can increase airflow resistance.
