Dust blocking effect of breathing valve folding medical mask

Everyone is familiar with masks. With the continuous improvement of the level of technology, there are more and more types of masks on the market. Recently,Mask a breathing valve folding mask has appeared on the market. What role can this mask play?

The dust blocking efficiency of the breathing valve folding mask is based on its blocking efficiency for fine dust, especially for breathing dust under 5 microns. Because this size of dust can directly enter the alveoli, it has a great impact on human health. In general gauze masks, the principle of dust suppression is mechanical filtration, that is, when the dust hits the gauze, it passes through layers of barriers to block some large particles of dust in the gauze. However, Mask some fine dust, especially dust smaller than 5 microns,Mask will pass through the gauze mesh and enter the respiratory system.
