N95 respirator is one of nine kinds of particle respirators certified by
NIOSH (National Institute of occupational safety and health). "N" means not
resistant to oil. "95" means the particle concentration in the mask is more than
95% lower than that outside the mask when exposed to a specified number of
special test particles. 95% is not the average, but the minimum. The degree of
protection is N95, which means that under the test conditions specified in NIOSH
standard, the filtering efficiency of the filter material of the mask for non
oily particles (such as dust, acid mist, paint mist, microorganism, etc.)
reaches 95%. N95 is not a specific product name. As long as the product meets
N95 standard and passes NIOSH review, it can be called "N95 mask". N90 type
respirator has a filtering efficiency of 90%.

p95, p99, P100, a total of 9. These protection levels can cover the protection
range of N95.
"N" means not resistant to oil, which is suitable for non oil particles and has
no limit on service time.
Medical surgical mask is the mask worn by medical staff when they work. It is
mainly used in medical outpatient, laboratory, operating room and other high
demand medical environment, with relatively high safety coefficient and strong
resistance to bacteria and viruses. Medical surgical masks can also be used to
prevent the spread of influenza and respiratory diseases. There are three layers
of medical surgical mask, from the outside to the inside are waterproof layer,
filter layer, comfortable layer, comfortable layer is a layer of gauze.
Summary and comparison:
In terms of protection ability: N95 mask > medical surgical mask > General mask
In terms of wearing comfort: General mask ≈ medical surgical mask > N95 mask
