Function

Individual protection products designed to prevent or reduce the dust in the air from entering the human respiratory organs to protect life safety;

Material: Anti-particulate masks are mostly constructed with two layers of non-woven fabric inside and outside, with a filter cloth (melt blown cloth) in the middle layer;

Filtration principle: Filtering fine dust mainly depends on the filter cloth in the middle. Because the melt blown cloth has the characteristic of static electricity, it can absorb small particles. Because the fine dust is adsorbed on the original filter, and the original filter is static and cannot be washed with water, the self-priming filter type anti-particulate respirator needs to replace the original filter regularly

Remarks: The international requirements for the use of anti-particulate masks are quite strict. The anti-particulate masks belong to the first level in personal protective equipment, which is higher than earmuffs and protective glasses. The more authoritative testing certifications include CE certification in Europe and NIOSH certification in the United States, while the Chinese standards are similar to the NIOSH certification in the United States.

Protection object: The protection object is divided into KP and KN. The so-called KP is capable of protecting oily and non-oily particles, while KN is only capable of protecting non-oily particles.

Protection level: China's protection level is divided into KP100, KP95, KP90 and KN100, KN95, KN90. Among them, KP100 and KN100 have the highest national standard requirements for filtration efficiency greater than 99.97%, so the safety of use is also the highest.

How to wear?

How to wear a mask correctly? How often do you change it?

In order to prevent infection, some people may wear medical masks all day long, but this will weaken the nasal mucosa, lose the original physiological functions of the nasal cavity, and reduce resistance. Therefore, in places with low population density and ventilation, there is no need to wear a mask.

What needs to be reminded is that the protective effect of any type of mask is time-effective and must be replaced regularly. It is recommended to replace the mask every 2 to 4 hours. If the mask is contaminated, it should be replaced as soon as possible.

The medical mask is folded and stored in a zip-lock bag when not in use. It is not recommended to take the mask off and put it in your pocket or bag directly. This will easily cause secondary contamination of the medical mask. Be sure to fold it and put it in a clean zip-lock bag, and fold the side that touches the nose and mouth facing inward.

 

Effectiveness of the mask

The effectiveness of disposable masks depends on the type and certification standards. In particular, the EN 149:2001-A1:2010 standard (AENOR, 2010) establishes a level 3 protection level, if any, by adjusting the mask to the face through the exhalation valve according to the leakage of all particles into the room. The permeability of the device should always be measured according to the arithmetic measurement of the laboratory test carried out by the carrier. these are:

FFP1 is 22%.

FFP2 is 8%.

FFP3 is 2%.
