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 the filter element can be replaced directly. Increasing the enzyme layer increases the thickness of the filter element, ensuring better fit and consistent sizing with the filter frame.Guaranteed compatible replacement for Mitsubishi Electric MAC-2330FT-E and MAC-3000FT-E filters. The upgraded design allows direct replacement of the filter element inside the existing frame.Black carbon filter: Carbon adhesion technology plays a key role in the air filtration cycle, helping to reduce odors and capture harmful substances from indoor air. This technology is highly effective for maintaining cleaner air conditioner interiors.Extra-long life and performance: Blue filter combined with activated carbon for extended use. The blue filter features ions produced through high-temperature oxidation. The enzyme is bonded to the fiber layer and will not shed over time, maintaining its effectiveness and durability.Recommended replacement every six months. The sticky carbon technology uses high-temperature ionic activated carbon. In addition to its long lifespan, it maintains strong deodorizing and filtration performance, improving upon the large pores and poor efficiency of traditional filters.Includes 4 lytic enzyme filters and 4 activated carbon filters. High-density, seamless belt construction with dissolving enzyme layer. Blue filter composed of dissolving enzymes and a pure layer, enhanced with oxidation ions.
