Technical Field
The invention relates to the technical field of protective masks, in particular to a respiratory filtering protective mask.
Background
Air pollution, such as smog, carries high concentrations of Particulate Matter (PM), including heavy metals, toxic chemicals and compounds, bacteria and viruses. These contaminants are typically derived from industrial activities, burning coal, automobile exhaust, and other sources of pollution. Particles are the most deadly form of air pollution because they can penetrate deep into the lungs and bloodstream and if they are not filtered from the breath can cause permanent DNA mutations, heart attacks, respiratory diseases, cancer and premature death (relevant studies indicate that these diseases are associated with respiratory air pollution).
Under normal circumstances, these conditions are avoided with personal respiratory protection devices, including masks and nostril filters. However, most masks on the market are not compatible with air pollutant filtration designs, and only a few brand masks are designed for filtering air pollutant particles, with ideal filtration efficiencies of 95% or higher for particles, especially for PM2.5 from smoke sources (particulate matter less than 2.5 microns in diameter). Because these masks are difficult to seal in actual use, contaminated air leaks into the mask through the gap between the mask and the user's face, greatly reducing the filtering effect, and even if the seal is in place, the air breathed by the user is fresh air, but the exhaled air is indeed contaminated air that may carry viruses and is directly discharged to the environment where the user is located, contaminating the public environment where the user is located, and also being a way for viral infection. This is the case when medical personnel with the new coronavirus are infected. This is a major drawback of this type of respiratory protection device.
