1. When used for safety protection of oily particles. The total use time of the R category is not more than 8 hours at a time; the total use time of the P category is not more than 40 hours, or a total of 30 days from the beginning of the application, whichever is earlier. .
2. Medical surgical masks cannot be washed with water, because cleaning will destroy the filter material of the protective mask and the structure of the protective mask; if it is not damaged or damaged, and when the hygiene requirements are met, it can be fully considered for reuse.
3. KN95 masks are not trademarks or well-known brands. KN95 masks are the lower-level regulations of the US NIOSH (National Institute of Occupational Health and Safety) for the filtration efficiency level of anti-particulate respirators used in US jobs. It means that the filtration efficiency of non-oily particles (such as smoke, oil mist, organic gas, microbial strains, etc.) is at least 95% under the specified testing standards.
4. The higher the filtration efficiency of the protective mask, the greater the frictional resistance to the respiratory system. Therefore, it is not good for the human body to wear medical surgical masks for a long time. Do not wear for a long time.
5. Regarding the difficulty of changing the frequency of masks, there is no confirmed result at this stage, and there is no requirement for the use time of masks in my country. Some scholars have done scientific research on the high efficiency of KN95 mask safety protection and wearing time. Data Display. KN95 masks were worn for 2 days, the filtration efficiency remained above 95%, the inhalation friction resistance did not change much, and the filtration efficiency was as low as 94.7% after three days of wearing.Zhejiang Antipollution Medical Equipment Co., Ltd
