Air pollution is a deadly killer. Of the top ten causes of death in Taiwan, except for accidents, the other nine are related to "air pollution". PM2.5 (fine suspended particles) in the air is 1/28 of the hair and 3 of the red blood cells. Although it is invisible to the naked eye, it can easily enter the body, invade the alveoli, penetrate the blood circulation system, and cause various diseases, ranging from asthma, allergies or dermatitis, to lung cancer and liver cancer, and the long-term accumulation is very serious.

Generally, the common face masks are mostly flat design, which cannot fit the face closely, so that suspended particles can still be sucked into the body through the gap, and the material is only a single thin layer. When the organic matter is adsorbed to a certain degree, it is no longer With effective granules, the protective power of this type of masks for PM2.5 is actually only about 30% ~ 80%, and it cannot completely filter the fine particles of PM2.5; like the US standard N95 and European standard FFP1 masks, the main function is Filtering suspended particles can resist more than 95% of virus particles of 0.3 microns or more, and can also block air pollutants up to about 80% to 99.7%, but because they are too tight, they often make it difficult for people to breathe. Can't wear it for long.
