NOVELTY - Germicidal air filter comprises 20-30 pts. wt. activated carbon cellulose, 3-15 pts. wt. graphene, 9-15 pts. wt. antibacterial agent, 2-15 pts. wt. polyethylene terephthalate, 6-13 pts. wt. polypropylene, 2-16 pts. wt. tourmaline nanoparticle, 7-10 pts. wt. hydrophobic agent, 3-8 pts. wt. binder suspension and 10-30 pts. wt. organic solvent. USE - Germicidal air filter. ADVANTAGE - The filter has good mechanical performance and impact strength and anti-folding property, simple preparation and low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of germicidal air filter comprising grinding activated carbon cellulose and graphene for 20-50 minutes into 200-500 mesh powder, adding polyethylene terephthalate and polypropylene, and stirring to get hollow fiber layer; mixing tourmaline nanoparticle and binder suspension at 40-50 degrees C for 30-90 minutes, wet spinning, soaking in organic solvent for 12-24 hours, adding hydrophobic agent, taking out, and drying; and mixing with antibacterial agent, spraying on hollow fiber layer surface, and naturally drying for 24-36 hours.
