What's the difference between smog mask and n95 mask?

The difference between n94 mask and n95 mask;

1, the protection effect is different.

Generally, the larger the number after kn, the stronger the protective effect, so the protective effect of kn95 is stronger than that of kn94.

2. Different filtration efficiency

For non-oily particles above 0.075, the filtration efficiency of kn94 is greater than or equal to 94%, while for non-oily particles above 0.075, the filtration efficiency of kn95 is greater than or equal to 95%.

Classification and use of masks:

1, gas mask: contact with toxic gas and dust, and emergency rescue.

2, activated carbon masks: mainly in industry, for example, most newly renovated new houses will contain toxic gases such as formaldehyde.

3.pm2.5 mask: a mask that mainly filters particles invisible to PM 2.5, such as foggy days.

4. Medical surgical masks: commonly used in hospital medical clinics, surgery, laboratories, nurses and medical staff.

5.N95 type mask: anti-particle mask, which can filter most toxic substances and is certified by NIOSH as an anti-particle mask.
