MERV 8 filters are effective at trapping 90% of the airborne particles found in the average home. MERV 8 filters work best in residential homes with average filtration needs. MERV 8 filters trap pollen, dust & lint, debris, particles from sanding or spray painting, and textile fibers from clothes or carpet. (If you are worried about outdoor air pollution, family members with respiratory issues, pets are in the home, then going with a higher MERV rating might be a good idea.) Choose the right size filter: Before buying a replacement filter, check your owner's manual to identify the right number or size of your filter – it could also be printed on the side of your existing air filter. Or measure the filter yourself for accurate sizing. Which way does the air filter go in? 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 implode and damage your HVAC unit.
