1. Honeycomb-shaped activated carbon filter mesh is made from the polyurethane cotton which attach on the powdery activated carbon. Its carbon content is between 35% and 50%.
2. This filter mesh has good adsorption, can be used in  the air purification, the elimination of volatility organic compound and eliminating the dust particle, the smog, the stink, the toluene and the methanol and so on.

1. Aperture: stoma, mesopore, macrospore(corresponding to 50-15ppi,ppi means the count of the hold in 1 inch)
2. Adsorption of benzene: ≥15%    Adsorption of ammonia: ≥12%
3. Resistance: Linear velocity of the gas : 1.0 m/s
4. Voltage drop ≤42 pa
