Frequently Asked Questions
How often should I replace refill paper in reusable filter frames?
Most manufacturers recommend swapping refills every 30–90 days depending on air quality and use. Inspect filters monthly for heavy dust or pets — replace sooner if visibly dirty or if airflow drops.
Will a higher MERV filter harm my HVAC system?
Higher MERV filters (like MERV 13) can add resistance to airflow in some older or undersized systems. Check your HVAC’s specifications; if in doubt, choose a mid-range MERV (11) or consult an HVAC pro before upgrading.
How do I avoid leaks or thread problems when installing a whole-house filter?
Tighten fittings to manufacturer torque guidance, use the supplied wrenches and the correct thread sealant or tape where recommended. Inspect brass inserts and thread junctions before pressurizing; replace damaged inserts and test for leaks after installation.
