How to wear dust masks

First, the dust filtration efficiency of dust masks is quite high. When using a mask, its effectiveness in blocking dust depends on the standard for measuring the ability to filter fine particles or respirable dust that is 5 microns or smaller. In general, gauze masks are more basic and rely on mechanical filtration. This means that when dust particles come into contact with the gauze, some larger particles are trapped by the multiple layers of fabric. However, fine dust, especially particles smaller than 5 microns, can easily pass through the mesh and enter the respiratory system. Some masks on the market use filter materials made of fibers that carry a permanent electrostatic charge. As small dust particles pass through these filters, they are attracted by the static electricity and become trapped, effectively preventing them from entering the lungs.

Second, the fit of the mask against the face is crucial. If the mask doesn't seal properly around the face, dust particles in the air can enter through the gaps. To ensure maximum protection, it's important to choose a mask that fits your face shape well and to wear it correctly, making sure it forms a tight seal around the nose and mouth.

Third, comfort is an essential factor when choosing a dust mask. A good mask should have low breathing resistance, be lightweight, feel comfortable during long wear, and be easy to maintain. For example, an arch-shaped mask not only provides better coverage but also enhances overall comfort, making it ideal for extended use in dusty environments.
