Mitsubishi MSZ-GS24NA & MSY-GS24NA Annual Mini Split Filter Pack
Product Details
This Mitsubishi annual replacement mini split filter pack is guaranteed to fit the following Mitsubishi mini split units: MSZ-GS24NA & MSY-GS24NA.
Nano Platinum Deodorizing Filters (2 included)
Mitsubishi’s Nano Platinum Filters use an advanced 3D filter surface infused with nanometer-sized platinum-ceramic particles to provide powerful deodorizing and antibacterial performance. This enhanced surface structure captures fine dust more effectively than conventional flat filters—helping reduce odors, improve air freshness, and inhibit the growth of bacteria inside your indoor unit.
These filters are washable for routine maintenance, but they are not lifetime filters. To maintain their original deodorizing strength and dust-collection performance, periodic replacement is required.
Filter Dimensions: 16 7/8" x 13 13/16"
Care & Maintenance: Vacuum every two weeks using a soft-bristle brush attachment. When visibly dirty, gently wash with mild detergent in lukewarm water (under 120°F / 50°C). Allow the filters to dry thoroughly in the shade—do not expose them to direct sunlight or high heat.
Important: Do not operate your indoor unit without filters installed. If continued operation is needed during cleaning, order a second set.
Replacement Recommendation: Replace annually for best performance.
The Mitsubishi Air Cleaning Filter (anti-allergy enzyme filter) is charged with static electricity, enabling it to attract and capture dust particles. This filter has enzymes to combat allergens, with the power to decompose harmful microbes such as bacteria, dust mites, and pollen.
- Maintenance & Care: For best performance, the Mitsubishi Anti-allergy mini split filter should be cleaned every 3 months and replaced every 12 months.
- Filter Dimensions: 16 1/2" x 3 1/4"
Mitsubishi MSZ-GS24NA annual mini split filter bundle contains four (4) filters (1-year supply). 2 Mitsubishi Nano Platinums, 2 Air Cleaning Filters. You'll receive four pieces in total.

At the same time, for the health and safety of everyone — our team, other customers, and the facilities these products are used in — we cannot resell opened or used filtration and air quality products. Our policy below is built around that reality. If you have any questions about a product before ordering, please reach out — we would rather help you get the right thing the first time than deal with a return after the fact.
