Your Fujitsu ASUH09KMAS or ASUH12KMAS requires routine maintenance and filter replacement for proper performance and to provide clean air in your environment. Fujitsu recommends the following replacement filters & maintenance: Two (2) Large Fujitsu "screen" filters with a slot designed specifically for our healthy air filter options. This Fujitsu mini split filter is treated during manufacturing to prevent mold growth. This feature on the filters gives you cleaner, healthier air inside your home, and the coating makes it easier to clean your air filter. Maintenance & Care: Fujitsu recommends cleaning the air filter in warm water with a mild, soapy mix or vacuum cleaner to remove the collected airborne dust and pollutants. After washing, the filter must be thoroughly air-dried before it can be placed back in the indoor unit. Failure to do so could cause microbial growth in the unit's coil! The Fujitsu "screen" mini split filter should be cleaned every two weeks and replaced every two years to ensure the best air-cleaning performance. Filter Dimensions: 12-5/8" x 12-9/16" The Fujitsu Catechin Hypoallergenic (White) Filter Maintenance & Care: This disposable air filter should not be washed. If this filter is washed, the media will be damaged. The Polyphenol air filter should also only be stored temporarily because as the filter ages, it loses the ability to clean the air as effectively. This filter should be replaced every three months. Filter Dimensions: 8- 1/2" x 1-3/8" The Fujitsu Negative Air Ion Deodorizing (Blue) Filters Maintenance & Care: The recommended cleaning process for the Negative Air Ion Deodorizing filter (Blue) is to clean it in warm water and mild detergent. The air filter should not be scrubbed with an abrasive pad or brush, as this will damage its deodorizing power. This filter should be cleaned every three months and replaced every year. Filter Dimensions: 8- 1/2" x 1-3/8" The Fujitsu Healthy Air Filters require specialty holders that attach properly to the large screen filters within your indoor unit.
