How to distinguish between non-oily particulate filter and oily particulate filter for face mask? June 23,2020.

There are many types of face masks on the market. Composite filter materials are the main components of masks. The general filter materials are: activated carbon fiber, activated carbon particles, melt-blown cloth, non-woven fabric, electrostatic fiber, etc. Of course, there are other special filter materials. It is mainly used to deal with other special toxic gases or radioactive particles.

Protective face masks can be classified according to the number of uses, execution standards and appearance.

According to the number of uses, it can be divided into disposable protective masks, multiple protective masks and recyclable protective masks.

According to the shape classification, it can be divided into half-mask type, full-face type, flat type, cup type, duckbill type and so on.

According to the implementation standard, it can be classified according to American NIOSH standard, European EN standard and Chinese GB2626-2006 standard:

Anti-haze masks can not only effectively block the intrusion of fine particles, but also ensure smooth and unobstructed breathing. Adjustable anti-haze masks that fit the face are the best choice. First of all, the filtering efficiency of the mask, the  larger the value, the better the protection effect of the filter material. Secondly, the tightness is better, the filtration efficiency is even higher, and if it is not worn tightly, it cannot provide effective protection. Finally, the breathing resistance of the face mask, the greater the resistance, the wearer will feel "stunned" and the less comfortable it is.
