How to Install Your MERV 11 Furnace Filter
Replacing your MERV 11 air filters takes about two minutes:
- Turn off your HVAC system before changing the filter.
- Locate the return air vent or filter slot on an interior wall, ceiling, or inside the furnace cabinet.
- Remove the old filter carefully and dispose of it without shaking (it may be heavily loaded with allergens).
- Note the airflow direction arrow on the old filter frame.
- Slide in your new Simply Filter, aligning the printed airflow arrow so it points toward the blower motor and away from the return air duct.
- Replace the vent cover and restart your HVAC system.
How Often Should You Replace MERV 11 Filters?
Simply Filters' MERV 11 filters are built to last up to 90 days, but the right schedule for your home depends on how quickly your filter loads with particles:
Every 30–45 days: Households with multiple pets, heavy shedding, or occupants with moderate-to-severe allergies or asthma.
Every 60 days: Homes with one pet, or residents with mild allergies.
Every 90 days: Pet-free homes with no allergy concerns and good baseline air quality.
Every 6 weeks: Households with children under 5 or elderly residents with respiratory sensitivities.
