We all know that when the air quality is not very good, we will choose to wear masks when traveling, in order to prevent harmful gases in the air from being inhaled into the lungs, thereby ensuring our health.
This is how the polytetrafluoroethylene mask film was born.
The new coronavirus is a solid, non-oily particle, so any mask that can effectively block bacteria and non-oily suspended particles can block the virus and play a role in preventing the new coronavirus.
There are various types of masks on the market, but in terms of function, there are only four categories: medical protective masks (N95/KN95, etc.), medical surgical masks, ordinary medical masks (disposable medical masks, etc.) and other mask-shaped protective items. .
For the vast majority of ordinary people who do not come into contact with patients, the most suitable mask is actually not a KN95/N95 mask, but a medical surgical mask that implements YY0469-2011 medical standards and has a bacterial filtration efficiency of more than 95%. .
So for us ordinary people, instead of rushing to buy N95 masks, it is better to go to pharmacies to buy more suitable medical surgical masks.
As a newly released third-generation mask filter element, PTFE mask membrane has successfully solved all the shortcomings of the second-generation mask and can be worn comfortably by people of all ages.
Interested parties can enter the store to inquire and purchase! The respiratory impedance of the polytetrafluoroethylene mask membrane is only 60-70pa, and the ordinary melt-blown non-woven mask is as high as 120-250pa. In comparison, the breathability of the film mask is already very good, but it certainly cannot be compared with not wearing a mask.
The wearing comfort of a polytetrafluoroethylene mask membrane mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of film materials, they can give users a more comfortable breathing experience.
