Air Filter Cleaning: Step-by-Step Guide 

Wondering how to clean an air filter? We’ve got you covered. Follow the steps below to get your air filter back to like-new condition:

  • Access the Air Filter: Air filters are typically encased in a housing to keep them clean and protected. You may need a screwdriver and/or wrench to access the air filter. Be sure not to shake any debris into the intake or airbox; simply remove the filter as cleanly as possible. 
  • Remove Loose Dirt, Dust, Etc.: After removing the air filter, hold it over a trash can and shake off as much loose debris as possible. 
  • Vacuum the Filter: Use a vacuum (ideally a handheld vacuum cleaner) to remove the finer dirt and grime from the air filter. 
  • Apply Air Filter Cleaner: Once the air filter has been vacuumed, you can apply an air filter cleaner, following the instructions on the package. You can also make your own cleaning solution using water and mild laundry detergent (2:1 ratio). Mix well, then spray it onto the filter. Allow it to set for a couple of minutes, then take the next steps. 
  • Scrub with a Brush: Use a soft brush to clean the air filter gently. A toothbrush is a good tool for cleaning the crevices. 
  • Rinse Thoroughly & Dry: Rinse the cleaning solution out of the air filter completely, then shake the filter. Position the filter so it’s hanging upside-down and can drip dry. Don’t apply heat; don’t use a hairdryer or throw it in the dryer. 
  • Reassemble the Filter: Put the filter back where you got it. If you removed the housing, be sure to reassemble it. 

Does the Cabin Air Filter Affect AC & Air Quality? 

A cabin air filter can have an impact on your air conditioner and air quality when commuting to and from Aurora. These filters can collect dust, bugs, leaves, and other types of debris. If the air filter becomes too dirty, it can reduce your air conditioner’s ability to cool down the cabin. This can cause issues for the entire air circulation system over time. Therefore, the straightforward answer to “Does the cabin air filter affect AC?” is yes — and the best way to ensure that your filter is clean is to replace it whenever necessary.
