The role of pm2.5 mask
Pm2.5 mask can deeply filter and block smog, effectively filter the invisible killers in the air-bacterial viruses, automobile exhaust, second-hand smoke, formaldehyde, dust mites, smog, volatile chemicals, air pollution gas, block the use of droplets, body fluids and secretions, and absorb and filter the pollution gas caused by automobile exhaust. , widely used in medical and health industries and public places. No matter the filtration efficiency, air permeability, antibacterial property and safety, it greatly exceeds that of ordinary masks.
PM2.5 masks have many preventive measures, so they have more functions than traditional masks. For example, its lead carbon fiber cloth can play an antiviral role, and filter paper can prevent more than 95% of dust from being inhaled into the body, so it is a better type of mask. Some industrial areas also use this kind of mask to prevent virus, because there may be certain chemicals or toxic gases in industrial areas, and the lead carbon fiber cloth of PM2.5 mask has anti-virus function.
Can pm2.5 mask prevent formaldehyde?
Pm2.5 mask can prevent formaldehyde.
The filter screen of pm2.5 mask is treated with nano-silver bactericide, which can not only filter bacterial viruses, but also filter toxic gases such as automobile exhaust, second-hand smoke and formaldehyde. Moreover, pm2.5 masks are higher than ordinary masks in filtration efficiency, air permeability, antibacterial property and safety.
Pm2.5 masks are widely used in air pollution prevention, pm2.5 prevention, antibacterial, antiviral, automobile exhaust prevention, formaldehyde decoration, absorption and filtration of toxic gases, etc. Products are certified by national authorities.
Is the pm2.5 mask really useful?
Experts recommend wearing masks professionally.
Some masks that claim to effectively isolate PM2.5 may be affected by air quality because the concept is greater than the actual effect. 20 13 10 3 1, the staff of Changchun Meteorological Bureau and Changchun Health Education Center said that the medical N95 mask had the best smog prevention effect.
The effect of PM2.5 mask is inconclusive.
PM2.5 mask has great respiratory resistance. Normally, the N95 mask is only worn when it comes into contact with very serious respiratory patients, such as when entering infectious wards such as SARS. Ordinary non-woven mask fibers can't stop PM2.5 particles at all, while activated carbon only works on gaseous toxic and harmful pollutants such as volatile organic compounds, and the filtering effect on particles that can enter the lungs is very limited. General cotton gauze masks only have dust-proof function, and professional protective masks such as N95 and KN90 can prevent respiratory infectious diseases and have a certain protective effect on PM2.5 [1].
Yan Haidong, a professor at Fudan University School of Public Health, once said that wearing N95 masks has little effect on blocking PM2.5. Masks can only block large polluted particles, but not tiny particles such as PM 2.5.
