ACTIVATED CARBON SUPERIORITY: Unlike conventional carbon-infused fabric, our high-density pelletized activated carbon granules provide 3X the adsorption surface area with vertically-aligned micro-pores that actively trap odor molecules and VOCs, while preventing particle escape and maintaining stable airflow—ensuring consistent performance without the premature saturation common in flat carbon pads. SUPERIOR ENGINEERING: MK01 filters are crafted with high-quality non-woven fabric, and pelletized activated carbon. They adopt advanced lower energy consumption and lower density structure technology, delivering reduced wind resistance, enhanced efficiency, and optimized pressure for effective filtration, promoting energy saving and a longer service life.
