In order to make the cleaning process easier on yourself, take these steps below:

  1. Unplug the unit from the power source.

  3. Use a vacuum hose (if possible) and suck up any dust particles from underneath where you removed the bottom or top parts of your air cleaner.

  4. Take out your air filter and rinse it off with water. Be sure to do this outside so that you don't make a mess inside.
