Steps for Air Filter Replacement to Improve Indoor Air Quality

  • Air conditioner filters are typically located in front of the evaporator component of your system. Check your owner’s manual or call your local HVAC expert for guidance.
  • You may need to remove a metal strip covering your system’s filter slot to get to your A/C or furnace filter.
  • Next, open any clips and remove screws holding the air filter in place.
  • Then, pull or slide the filter out. If you don’t have a replacement ready, measure your filter and note this information along with the manufacturer and part number then put the filter back in until you have the new replacement filter. You should also check your owner’s manual. Do not run your system without an air filter as this would plug your coils.
  • Contact your HVAC contractor or filter manufacturer, and check your hardware store for a replacement. If you’d like a higher level of filtration, your heating and air conditioning company can recommend options for you.
  • Next, you should slide your replacement filter in place of your old one. Make sure the side marked with arrows or “Air In” faces the correct direction.
  • Finally, replace the metal strip, clips or screws holding the filter in place and you’re on your way to cleaner, fresher indoor air.
