The filter membrane is made of non-toxic anti-bacterial/viral non-woven plus polypropylene synthetic fiber, and the fibers are self-charged; when the air passes through the filter, the static electricity causes the particles to change their trajectory and hit the filter membrane, while the static electricity makes the particles stick more firmly on the filter membrane. After the air in the breathing tube is filtered, it is cleaner, safer, and reduces the incidence of lung infection.
