How much do you know about the dust blocking efficiency of non woven masks? 2020-05-12
The dust blocking efficiency of the non woven mask is based on its blocking efficiency for fine dust, especially for respiratory dust below 5 microns. Because this size of dust can directly enter the alveoli, it has the greatest impact on human health.

In general gauze masks, the dust blocking principle is mechanical filtering, that is, when the dust hits the gauze, it passes through layers of barriers and blocks some large particles of dust in the sand cloth. However, some fine dusts, especially those smaller than 5 microns, will pass through the gauze mesh and enter the respiratory system.

At present, there are somedust masksabroad, and the filter material is composed of fibers filled with permanent static electricity. Those respiratory dusts smaller than 5 microns are attracted by static electricity and absorbed in the filter material during the process of passing through this filter material dust really plays a role in preventing dust.

Air is like water flow, wherever resistance is small, it flows first. When the shape of thenon-woven maskis not tightly closed to the face, the dangerous objects in the air will leak from the non-closed place and enter the respiratory tract.

Then, even if you choose a mask with the best filter material. Nor can it protect your health. Many foreign regulations and standards stipulate that workers should regularly test the adhesion of non-woven masks. The purpose is to ensure that workers choose a non-woven mask of the appropriate size and wear the mask according to the correct steps. Respiratory resistance is required to be small, light weight, hygienic wearing and easy maintenance. In this way, workers will be happy to wear them in the workplace and improve their work efficiency. 

Current maintenance-free masks abroad do not need to be cleaned or replaced. When the dust barrier is saturated or the mask is damaged, it is discarded. This not only ensures the hygiene of the non-woven mask, but also saves the workers time and effort to maintain the mask. Moreover, many masks adopt an arch shape, which can not only ensure a good adhesion with the shape of the face, but also reserve a certain space at the non-woven mask, which is comfortable to wear.
