Genuine Fujitsu OEM Replacement Filter for Mini-Split Systems The Fujitsu UTR-FA16 (K9315361035) Apple-Catechin Filter is a genuine OEM replacement air filter engineered for Fujitsu General mini-split ductless heating and cooling systems. Named for its active ingredient, the filter media is treated with catechin — a natural polyphenol antioxidant derived from apples — that works alongside a static-electric charge to capture and neutralize airborne contaminants as they pass through the unit. Fujitsu describes the technology simply: the Apple-Catechin filter uses static electricity to clean fine particles and dust from the air. Beyond basic particle capture, the apple-derived polyphenol coating is engineered to absorb fine dust, invisible mold spores, and harmful micro-organisms, while inhibiting and deactivating their growth on the filter surface — supporting a cleaner, fresher indoor environment. The technology has earned Sensitive Choice approval from the National Asthma Council Australia, recognizing its benefit for households managing asthma and allergies.
