Fujitsu K9309997011 OEM replacement filter for the following Fujitsu ductless mini split units:
Model Number: ASU9R2, ASU12R2, ASU18CL, ASU18RL
All of the above indoor units require 2 replacement air filters.
The Fujitsu K9309997011 replacement air filter is treated during manufacturing to prevent the growth of mold. This feature on the filters gives you the option to have cleaner, healthier air inside your home. The coating also makes it easier to clean your air filter.
Fujitsu recommends that the air filter is cleaned in warm water with a mild soap mix, or with a vacuum cleaner to remove the collected airborne dust and pollutants. After washing the K9309997011 it must be thoroughly air dried before it can be placed back in the indoor unit.
The Fujitsu K9309997011 should be cleaned every two weeks to ensure the best air cleaning performance of the filter.
