The upgraded filter maintains compatibility and allows direct replacement of the filter element. Black carbon filter: Carbon adhesion technology plays a key role in the air filtration cycle, helping to clean the interior of the air conditioner and remove odors and harmful substances from indoor air. This technology is highly recommended. Extra long life and performance: Blue filter and activated carbon stick provide extended service life. The blue filter is produced through high-temperature oxidation. The dissolving enzyme is fixed on the fiber layer and will not fall off over time, maintaining its dissolving ability and resulting in a durable, long-lasting filter. Recommended replacement every six months. The sticky carbon technology filter is a type of high-temperature ionic sticky carbon. In addition to its ultra-high lifespan, it maintains deodorizing and filtration effectiveness over time, improving upon the large pores and poor performance of traditional filter elements. Includes 4 lytic enzyme filters and 4 activated carbon filters with high-density seamless belt dissolving enzyme.
