How to Install an Air Conditioner Filter

The filter for your air conditioner should be changed every 3 months. Fresh filters reduce the circulation of dust, pet fur, and pollen throughout the vents. Learning how to install an air conditioner filter takes only moments. When selecting a filter, you may choose to balance air movement efficiency with filtration capability. Dense filter material will pull more particles from the air but also force the air conditioner to work a little harder.

Tools You’ll Need

You’ll only need a screwdriver if screws are holding a vent grate in place.

• Dust rag
