NO FRAMES ARE INCLUDED. YOUR EXISTING WHITE INSERT FRAMES MUST BE INSTALLED WITH THESE FILTERS. Dimensions for filter media: 8.3 Inch x 1.9 Inch x 0.2 Inch (21 x 4.7 x 0.5 cm). When replacing, you only need to remove the filter element in the old frame and replace it with the new filter element. Replacement process is quick and easy. The upgraded filter maintains compatibility and allows direct replacement of the filter element. Increasing the dissolving enzyme layer also increases the thickness of the filter element, ensuring better fit and consistent sizing with the filter frame. 100% guaranteed compatible replacement for Mitsubishi Electric MAC-2330FT-E and MAC-3000FT-E filters. The upgraded design maintains full compatibility and enables direct replacement of the internal filter element only. Black carbon filter: Carbon adhesion technology plays a key role in the air filtration cycle, helping to clean indoor air by reducing odors and harmful substances inside the air conditioner. This technology is highly effective and recommended for improved air quality. Extra long life and performance: Blue filter combined with activated carbon for extended durability. The blue filter is produced through high-temperature oxidation. The dissolving enzyme is securely fixed on the fiber layer and will not degrade over time, maintaining long-term effectiveness and extending filter lifespan. Recommended replacement every six months. The sticky carbon technology uses high-temperature ionic activated carbon. In addition to its long service life, it provides sustained deodorizing and filtration performance, improving upon the large pores and poor efficiency of traditional filter elements. Includes 4 lytic enzyme filters and 4 activated carbon filters. High-density seamless belt with dissolving enzyme for enhanced filtration efficiency.
