MERV 11 filters are effective at trapping 95% of airborne particles in a typical home. MERV 11 filters work best in residential homes with higher filtration needs than MERV 8 filters provide, and commercial buildings, senior living facilities, and non-surgical hospital areas. MERV 11 filters trap dust & Lint, pet dander, smoke, smog, auto exhaust. (If anyone has an allergy or respiratory problem, go with a MERV 11 air filter.) Before buying a replacement filter, check your owner's manual to identify the right number or size of your filter – it should also be printed on the side of your existing air filter. Or measure the filter yourself for accurate sizing. The arrow on your air filter should point to the blower in your HVAC unit. If the filter is in the wall or ceiling in your home, then the arrow on the filter should point to the wall or ceiling. NOTE: If you put the air filter in backward, then you run the risk that the filter will collapse and damage your HVAC unit.
