Fujitsu K9332549010 OEM replacement filter (Old Part K9332549003). This filter is designed to fit the following models of Fujitsu mini splits:
ASU12RL2, ASU9RL2, ASUA4TLAV1, ASUA7TLAV1, ASUA9TLAV1.
All of the above indoor units require two replacement air filters.
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 K9332549010, it must be thoroughly air dried before it can be placed back in the indoor unit.
The Fujitsu K9332549010 should be cleaned every two weeks to ensure the best air-cleaning performance of the filter.
Two filters are included in this pack.
