I want to buy a dust mask. What kinds of dust masks are there and which one is better?

The dust mask currently implements gb2626-2006 Respiratory Protective Articles-Self-priming Filter Respirator for Releasing Particulate Matter.

Firstly, according to the standard protective mask, it can be divided into oil-proof particles (oil fume, oil mist and non-oil particles) and non-oil particles (dust, smoke, fog, microorganisms, etc.). ).

According to the protection effect, it is divided into three grades: 90, 95, 100. Marked as kn90, kn95, kn 100, kp90, kp95, kp 100 respectively. Among them, the protective ability of kn 100 and kp 100 to ultrafine particles is above 99.97%.

If you work or live under dust, it is suggested that you must do a good job of respiratory protection for your health. Choose a dust mask scientifically and choose a good mask with good protective effect, smooth breathing and economical use. Helps prevent lung injury.

Methods of cleaning dust: Now dust masks must implement gb2626-2006 standard. Dust masks are divided into kn 100, kn95 and kn90. Among them, the protective effect of kn 100 on ultrafine dust can reach nearly100% (more than 99.97%). If the particle size is large, you can choose kn95 grade. The protection effect depends on two aspects. One is the filtration efficiency of cotton filter. The second is the air leakage rate after the mask is matched with the face.

Methods of cleaning dust: Scientific selection of dust masks certified by gb2626-2006 is helpful to prevent lung injury.
