China N95 masks made in China is one of the 9 kinds of particulate protection masks certified by NIOSH. "N" means not resistant to oil. "95" means that when exposed to a specified number of special test particles, the particle concentration in the mask is more than 95% lower than the particle concentration outside the mask. The 95% value is not the average value, but the minimum value. N95 is not a specific product name, as long as it meets the N95 standard, and products that pass the NIOSH review can be called "N95 respirator." The protection grade of N95 means that under the test conditions specified by the NIOSH standard, the filtering efficiency of the mask filter material to non-oily particulate matter (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%.
The N95 masks Factory has a filtration efficiency of more than 95% for particles with an aerodynamic diameter of 0.075µm±0.02µm. The aerodynamic diameter of airborne bacteria and fungal spores mainly varies between 0.7-10µm, which is also within the protection range of N95respirator. Therefore, the N95 masks can be used for the respiratory protection of certain particulate matter, such as the dust generated by the processes of grinding, cleaning and processing minerals, flour and certain other materials. It is also suitable for the liquid or non-oily generated by spray particulate matter of harmful volatile gas. It can effectively filter and purify the inhaled abnormal odors (except toxic gases), help reduce the exposure level of certain inhalable microbial particulates (such as mold, anthrax, tuberculosis, etc.), but it cannot eliminate contact infection, illness or risks of death.
Which one is better, N95 mask or KN95 mask?
In the United States, only N95 masks are approved for health care use. KN95 masks have many of the same protective properties. We advise people to be cautious when purchasing KN95s in the United States, as many are fake and do not meet NIOSH requirements.
How long can N95 masks be worn?
There is no time limit for wearing an N95 mask. Masks can be worn until they become dirty, damaged, or until it becomes difficult to breathe. To be effective, N95 masks need to be worn correctly.
How to wear ear-worn N95 masks?
1. Loosen the fixing strap
If you want to wear an ear-worn N95 mask, you first need to loosen the fixed straps, and also face the inside of the mask, and pull one ear strap with both hands.
2. Wear the earband behind your head
Next, place the mask against your chin, then pull the ear straps to the back of your head, and adjust the ear straps to make them feel comfortable. If the ear straps are too long, the mask will be loose when worn, so be sure to adjust them properly.
3. Adjust the position of the nose clip
Place the fingers of both hands on the center of the metal nose clip, and then press inward. While pressing, move your fingertips along both sides of the nose clip so that the mask can fit tightly on the face and bridge of the nose.
4. Check the tightness
Use one hand to gently press the mask, and take a few breaths deliberately to see if the mask is leaking. If it is not leaking, it means you are wearing it successfully. If it is leaking, you need to adjust it.
In addition to the filtration efficiency of CE N95 masks, the adhesion between the mask and the face is one of the important factors that determine the effectiveness of the mask. Different types of respirators have a big difference from the suitability of the human face. Therefore, before using the respirator, the suitability of the mask should be checked first. After the wearer's face tightness test, ensure that the air can enter and exit through the respirator when it is close to the edge of the face.
