Dust Resistance Efficiency of Non-woven Masks

Ⅰ. Usage of the non woven mask

For the choice of the filter non woven mask, some manufacturers provide you with the following convenience, that is, you can use the same mask with the corresponding filter cotton when you need to work in the dust environment, so you wear a dust mask. When working in the toxic environment, replace the cartridge with a chemical cartridge to get a respirator again. Get more combinations depending on your job needs.

Ⅱ. Dust resistance efficiency of the non woven mask

The dust blocking efficiency of a non-woven mask is based on its barrier efficiency for fine dust, especially for respirable dust under 5 microns. Because this particle can directly enter the alveoli, causing the most significant impact on human health. In general gauze masks, the principle of dust resistance is mechanical filtration. That is, when dust collides with gauze, some large particles of dust are separated in gauze through "layer upon layer of barrier". However, some fine dust, especially those smaller than 5 microns, can pass through the mesh of the gauze and enter the respiratory system. There are some dust masks that can capture fine dust. The filter material is composed of permanent electrostatic fibers. When passing through this filter material, the respirable dust is attracted by static electricity and is adsorbed in the filter material.

Air is like a stream of water, where the resistance is small, it flows first. When the shape of the non-woven mask is not close to the face, the dangerous things in the air will leak into the respiratory tract. So, even if you choose good mask it will not protect your health. Many regulations and standards require that workers be tested regularly for the tightness of non-woven masks. The purpose is to ensure that workers choose non-woven masks of the appropriate size and wear them properly.

The breathing resistance of the mask should be small, the weight should be light, the using is hygienic, and the maintenance is convenient so that workers will be willing to wear it at workplace while improve their work efficiency. The maintenance-free masks do not need to be cleaned or replaced. When the dust barrier is saturated, or the mask is damaged, it will be discarded. This guarantees the hygiene of the non-woven mask and saves workers the time and energy of maintaining the mask. In addition, many masks adopt arched shapes, which can ensure a good fit with the shape of the human face and reserve a certain amount of space at the non-woven mask, which is comfortable to wear.
