Although the structure of the dust mask is simple, it is not easy to use. Choosing a suitable and suitable mask is only the first step in protection. If the protection is really effective, it must be used correctly. This includes not only wearing it according to the instructions for use, ensuring that it is worn in the correct position (no leakage) every time, but also must be in the dusty operation. Insist on wearing the mask, find the signs of failure of the mask in time, and replace it in time. Different dust exposure environments have different dust concentrations, different use times for each person, different dust holding capacity of various dust masks, and different use and maintenance methods, all of which will affect the service life of the masks, so there is no way to uniformly stipulate the specific replacement time. . When any part of the dust mask is broken, broken, and missing (such as nose clips, nose clip pads), and when there is a noticeable increase in breathing resistance, the entire mask should be discarded.
No matter whether it is anti-virus or dust-proof, any filter element should not be washed with water, otherwise it will destroy the filter element. If you feel other discomfort during use, such as the headband is too tight, the resistance is too high, etc., it is not allowed to change the length of the headband without authorization, or loosen the nose clip, etc., you should consider choosing a more comfortable mask or other type of respirator. The respirator is not only suitable for users, but also should have a certain degree of comfort and durability, which is reflected in the slow increase in breathing resistance (large dust holding capacity), light mask, headband not easy to loosen, mask not easy to collapse, nose clip or head The belt is firmly fixed, the material selection has no odor and is not irritating to the skin, etc. This is usually only those workers who have used dust masks for a long time have the most experience and the most say.
