About These Filters

Large Screen Filter: This is Fujitsu's large screen filter: the washable mesh filter in the indoor unit's intake that provides the system's baseline filtration and protects the coil and fan from dust and lint. Fujitsu treats it during manufacturing to resist mold and mildew growth, and its operating manual describes these as easy-to-care air filters that resist mildew growth. On units that use Fujitsu's optional air cleaning filters, those filters mount on the screen filters.

Apple-Catechin Filter: This is an optional disposable air cleaning filter that mounts on the large screen filter. Fujitsu describes it as using static electricity to clean fine particles and dust from the air. Its media is treated with catechin, a polyphenol derived from apples, which Fujitsu says absorbs fine dust, mold spores and micro-organisms while inhibiting and deactivating their growth on the filter surface. Fujitsu states that its Apple-Catechin filter technology has received Sensitive Choice approval from the National Asthma Council Australia.

Ion Deodorizing Filter: This is an optional washable air cleaning filter that mounts on the large screen filter. Fujitsu describes it as deodorizing by decomposing absorbed odors through the oxidizing and reducing effects of ions generated by an ultra-fine-particle ceramic. Fujitsu notes it can be used for about 3 years if it is washed with water when dirty to restore its surface action.

Filter Holder Frame: These are genuine Fujitsu holder frames. They clip onto the indoor unit's large screen filters and hold the air cleaning filters in place. Replace them if the originals are cracked, brittle or missing tabs.

How Many Do You Need?

Owner's manuals list Fujitsu's air cleaning filter set, which pairs one Apple-Catechin filter with one Ion Deodorizing filter. That is what one indoor unit holds at a time, but the two filters are on very different schedules: the Apple-Catechin filter is replaced every 3 months, while the Ion Deodorizing filter is washed every 3 months and lasts about 3 years. So over a year, one indoor unit uses four Apple-Catechin filters and only one Ion Deodorizing filter. A second Ion Deodorizing filter is handy as a spare to rotate in while the other dries.

This listing includes:

• 1 Apple-Catechin filter: about 3 months of replacements for one indoor unit
• 1 Ion Deodorizing filter: lasts about 3 years with regular washing

Care & Replacement

Large screen filters: Clean every two weeks. Vacuum the filter, or wash it in warm water with a mild detergent, then let it air-dry completely in the shade before reinstalling. Do not run the indoor unit without its filters installed. Screen filters are not lifetime filters: replace every 1 to 3 years based on wear. Regular cleaning gradually wears the filter and its anti-mold treatment, so we recommend replacing it annually for best performance, and sooner if it is torn, warped or will not come clean.

Apple-Catechin filters: Do not wash: washing damages the filter media. Replace every 3 months. The catechin treatment loses effectiveness as it ages, so keep spare filters sealed until you need them.

Ion Deodorizing filters: Clean every 3 months in warm water with a mild detergent. Do not scrub it with an abrasive pad or brush, which damages its deodorizing ability. Let it dry completely before reinstalling. Replace about every 3 years.

Holder frames: Reusable. Replace a frame if it is cracked, brittle or missing tabs.
