Replacement Schedule

Replace every 90 days for standard use

Not every home needs premium filtration. If you don't have pets, allergies, or air quality concerns, a MERV 8 pleated filter does exactly what your HVAC system needs: it catches dust, pollen, lint, and carpet fibers while protecting the system's internal components from particle buildup.

MERV 8 is the baseline for quality pleated filters. Anything lower (MERV 1 through 4) is a flat fiberglass panel that barely catches anything. MERV 8 is the starting point for real filtration. It has the lowest airflow restriction of any effective filter rating, which means your HVAC system runs efficiently with no risk of strain.

The price difference between MERV 8 and higher ratings is significant over time. At $25 per 6-pack replaced every 90 days, you're spending roughly $100 per year on filters. Stepping up to MERV 13 at $50 to $70 per pack doubles or triples that annual cost. If you don't need the extra filtration, there's no reason to pay for it.
