Low resistance Polyethylene + polyene hot melting material can reduce the wind resistance of filters. High dust holding capacity The gradually changing density can increase the dust holding capacity, prolong the service life of filter, and reduce the replacement cost.

Conventional method: activated carbon adsorption At high temperature and when saturated, there is a risk of secondary omission. TICA solution: chemical removal of formaldehyde The filter surface is evenly applied with primary amine, which can decompose formaldehyde without the risk of secondary omission.

Metallic ions can interfere with cell wall and cytomembrane synthesis. Then, cells could be killed since the cell wall and cytomembrane lost the completeness. Metallic ions can suppress protein synthesis and kill bacteria, so as to effectively prevent microorganism breeding.
