The colorful cotton, linen, and certain fiber masks sold on the market are all civilian-grade masks, which basically have no protection ability, and the main function is to keep warm and block the dust on the face. It is important to choose a mask that suits your face. A mask that fits your face tightly is much more effective than a mask with a nominal protective capacity. The protective effect of the mask itself is not the same as the final protective effect. If we choose a mask that does not fit well with the facial curve, or is not worn properly and has poor sealing, it will also cause the actual protective effect to decrease or even disappear.

Among the professional dust masks, the professional dust masks that meet our national standards of KN90 level can basically meet the needs. However, it should be noted that relatively high filtration efficiency masks may also have higher resistance, that is, wearing comfort will be slightly reduced, so you must make a trade-off based on your actual situation. To evaluate the effectiveness of a masks protective effect, we must not just look at the filtering efficiency, we must look at the filtering efficiency, wearing tightness, and wearing time. So to evaluate which kind of mask is the best, we need to consider many aspects. Suitability also varies from person to person.

The N95 dust mask is hard in texture and the protective material is tightly sealed. Soon after wearing, it is prone to discomfort and breathing is not smooth. The better the protective effect, the more difficult it is to breathe after wearing, which is not suitable for the elderly and children. Relatively speaking, the KN90 dust mask is better, and the degree of breathing is not as uncomfortable as the N95. Capable of filtering particles greater than or equal to 90%.
