Compared with the protection level of these two kinds of masks, the N95 mask is better than the KN90 mask. Both of them caneffectively protect non-oil dust particles, and both of them can be used as anti haze masks.

KN90 respirator

KN90 respirator is suitable for the industries of non-ferrous metal processing, metallurgy,steel,coking, gas, organic chemicalindustry, food processing, construction,decoration, petrochemical, asphalt and other oil and non-oil particle polutants such asdust, smoke, fog, etc.

As a professional respirator, theKN90 respirator can capture more than 90% of particles under 2.5 u m in the protection abilitytest. Although it is not as good as N95 in particle protection, the KN90 respirator is relatively comfortable.

Users may feel a little stuffy when breathing.But it will not have a great impact on outdoor travel.For some people withrespiratory diseases, the KN90 respirator is also a good choice if they want to travel in a haze for a short time.

N95 respirator

N95 is the first standard proposed by NIOSH."N refers to "not resistant to oil” and "95" refers to that under the detectionconditions specified in NlOSH standard, the barrier rate of 0.3 u m particles must be more than 95%.

Therefore, N95 is not a specific product name, but a standard. As long as the respirator passes NIOSH review and reaches thisstandard, it can be called "N95".

N95 masks often have a breathing valve device, which looks like a big mouth, so N95 is also commonly known as a "pig mouthmask ". The transmittance of N95 is less than 0.5% in the protective ability test for particles below PM2.5.In other words, morethan 99% of the particles are blocked outside.

Therefore, N95 respirator is used as personal protective equipment for occupational respiration to protect some microbialparticles (such as viruses, bacteria, mold,tuberculosis, anthrax,etc.).N95 is undoubtedly one of the most common masks withthe best filtering protection effect.

However, although the N95 has a high degree of protection, there are some performance limitations. This makes the N95respirator not suitable for all people. It is also not a "foolproof” means of protection.

First of all, N95 has poor air permeability and comfort.lt is not suitable for the elderly with chronic respiratory diseases andheart failure to wear it for a long time to avoid breathing difficulties.

Secondly, when wearing an N95 mask, the nose clamp and jaw should be pinched tightly.The respirator and the face shall beclosely fitted to prevent particles in the air from being inhaled into the body through the gap between the respirator and theface. However, due to the different face shapes of each person, if the design of the respirator is not suitable for the user's faceshape, it may cause leakage.

In addition, the N95 respirator can not be washed with water. Its service life is 40 hours or 1 month.Therefore, the cost issignificantly higher than other masks.Consumers can't buy N95 blindly because it has a good protective effect. Whenpurchasing N95 masks, the purpose of protection and the special situation of users should be fully considered.
