Round Square HEPA Air Clean Filter HEPA Activated Carbon Filter High Odor Removal Efficiency

Carbon-filled non-woven fabric uses coconut shell activated carbon powder as an adsorbent material, attaching it between two layers of non-woven fabric or long-fiber substrates. It has a high carbon content, excellent adsorption effect, good breathability, low airflow resistance, and good formability (can be cut and folded at will). It has certain corrosion resistance to common solvents, weak acids, and weak bases.

The carbon-filled non-woven fabric is made by interlayering carbon between multiple layers of non-woven fabrics with different filtration performances, resulting in an orderly composite. It possesses the physical properties of fabric materials (strength, flexibility, durability), as well as the adsorption and microporous filtration capabilities of activated carbon. It is mainly used for air purification inside car cabins, capable of adsorbing unpleasant odors and harmful gases such as benzene, toluene, sulfur dioxide, hydrogen sulfide compounds, and ammonia. It is particularly effective in adsorbing smoke while also filtering dust particles.

Car filters are designed with a pleated structure, which effectively increases the filtration area, enhances adsorption and filtration performance, and extends the service life. This design reduces the air resistance of the filter, resulting in a smaller pressure drop, allowing for environmental purification under a certain air volume.
