MERV 13 Air Filters — HVAC, Furnace & AC

MERV 13 is the top MERV rating we stock for non-HEPA applications. ASHRAE and the CDC recommend MERV 13 for residential and commercial indoor air quality wherever the HVAC system can support it—common spec for healthcare, schools, and high-end commercial buildings.

What MERV 13 Captures

  • Hospital-grade filtration (ASHRAE 170)
  • Smoke and wildfire particulate
  • Bacteria and virus carriers
  • Fine dust and most airborne allergens
  • Sub-micron particles down to 0.3 microns

What It Doesn't Capture

  • Individual virus particles (requires HEPA)

Is MERV 13 Right for My System?

Best for: healthcare facilities, schools, wildfire-prone regions, immunocompromised households, severe allergies and asthma, ASHRAE 170-compliant environments.

Not ideal for: older systems with small blower motors or commercial AHUs with tight static-pressure budgets—verify the system can handle the pressure drop before switching.

How Often Should I Change a MERV 13 Filter?

Every 60–90 days for 1″ and 2″ filters in a typical residential or light-commercial system. Homes with pets, high occupancy, or heavy HVAC cycling may need every 30–60 days. 4″ and 5″ media cabinets typically run 6–12 months.
