What's Included 2× E22 C92 100 Catechin washable mesh pre-filter | 17-3/4" × 18-3/8" | Genuine OEM Mitsubishi 1× MAC-1415FT-E Anti-allergy enzyme filter | 2-13/16" × 13-7/16" | Genuine OEM Mitsubishi E22 C92 100 — Catechin Washable Pre-Filter The E22 C92 100 is a reusable plastic woven mesh pre-filter treated with Catechin — a bioflavonoid compound derived from green tea with antiviral, antioxidant, and deodorizing properties. The Catechin treatment actively works to inhibit bacteria and viruses on contact while helping to neutralize odors at the filter surface rather than simply trapping them. Dimensions: 17-3/4" × 18-3/8"Quantity required per unit: 2Maintenance: Clean every two weeks. Replace every 12 months.Type: Washable and reusable MAC-1415FT-E — Anti-Allergy Enzyme Filter The MAC-1415FT-E is a blue anti-allergy enzyme filter that attaches directly to the unit's plastic-framed pre-filter. It captures fine dust, pollen, airborne bacteria, viruses, and germs that pass through the larger mesh pre-filter. A specialized enzyme coating breaks down the protein bonds in allergens rather than simply collecting them — reducing allergen load in the space rather than just relocating it. Dimensions: 2-13/16" × 13-7/16"Quantity required per unit: 1Maintenance: Clean every three months. Replace annually under normal conditions. Replace more frequently in homes or offices with pets, young children, wall-to-wall carpeting, or poor outdoor air quality.Type: Disposable Genuine OEM Mitsubishi Filters Both filters in this bundle are genuine OEM Mitsubishi parts — manufactured to the same specification as the filters that shipped with your unit. Aftermarket alternatives are available on the market, but fit, filtration performance, and Catechin/enzyme treatment concentration vary. If your unit shipped with these filters, these are the correct replacements.
