What Kind Of Mask Is Better?

Now masks must implement the GB2626-2006 standard. The grades of dust masks are divided into three grades: KN100, KN95, and KN90. Among them, KN100 can achieve nearly 100% (above 99.97%) protection effect on ultrafine dust (particle size 0.75 microns). If the particle size is large, KN95 grade can be used.

The protective effect of dust masks depends on two aspects. Once was the filtration efficiency of the filter cotton. The second is the tightness of the combination of the mask and the face.

Therefore, masks must be divided into sizes, and the fit of masks regardless of size and face varies from person to person.

1. Select the duplex half mask type. Disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate.

2. Select KN100 grade dust filter cotton to use. Low protection rate will result in bodily harm.

3. It is more comfortable to choose the silicone material. Suitable for long-term wear, not easy to cause allergic reactions. Masks with high hardness are easy to cause facial indentation.

4. Masks are divided into sizes, which is extremely important. Don't buy those so-called generic masks. Easy to leak.

5. There are 2 types of masks covering the mouth and nose, covering the mouth and nose, and the lower jaw. It is recommended to use the latter, which is relatively comfortable.

6. It is recommended to choose a smooth breathing mask. Some masks are designed with double filter cotton, and the filter cotton has both sides, so that such masks are relatively smooth to breathe.
