A face mask is a sanitary product, generally refers to a device worn on the nose and nose to filter the air entering the nose and
nose to prevent harmful gases, odors, and droplets from entering and exiting the wearer's nose and nose, and is made of gauze or
paper.
Masks have a certain filtering effect on the air entering the lungs. When respiratory infections are prevalent, wearing masks has
a very good effect when working in a polluted environment such as dust.
Masks can be divided into air filter masks and air supply masks.
How to Choos Mask?
dust blocking efficiency
The dust blocking efficiency of a mask is based on its blocking efficiency against fine dust, especially respiratory dust below
2.5 microns. Because this particle size can directly enter the alveoli, it has the greatest impact on human health. Gauze masks,
the principle of dust blocking is mechanical filtering, that is, when the dust hits the gauze, through a layer-by-layer barrier,
some large particles of dust are blocked in the sand cloth. For some fine dust, especially dust smaller than 2.5 microns, it will
pass through the mesh of gauze and enter the respiratory system. Dust masks consist of filter material activated carbon fiber felt
or non-woven fabric. Respirable dust smaller than 2.5 microns is blocked during the passage of this filter material to filter air.
Folding tightness
The anti-side leakage design of the mask is to prevent air from being sucked in through the gap between the mask and the human
face without filtering, considering technical requirements. Air is like water flow, where the resistance is small, it flows first.
When the shape of the mask is not close to the human face, dangerous substances in the air will leak from the close to the human's
respiratory tract. Well, even if you choose a filter with the best mask. Nor can it protect your health. Many foreign regulations
and standards stipulate that workers should regularly perform mask tightness tests. The purpose is to ensure that workers choose
appropriate masks and wear them in the correct steps.
Comfortable for folding
In this way, workers will be willing to wear them in the workplace and improve their productivity. At present, maintenance-free
masks in foreign countries do not need to be cleaned or replaced, and are discarded when the dust blocking is saturated or the
mask is damaged. This not only guarantees the hygiene of the mask, but also saves the time and effort of workers to maintain the
mask. In addition, many masks are arch-shaped, which can not only ensure a good fit with the shape of the face, but also retain a
certain amount of space at the mouth and nose, which is comfortable to wear.
Unwell people
People with heart or respiratory problems (such as asthma emphysema), pregnancy, dizziness after wearing, difficulty breathing,
and sensitive skin.
What is N95 face masks?
N95 face masks, also called P2 or respirator masks, are designed to filter out fine particles from the air. They can protect
wearers from things like smoke, dust, fumes and — in some cases — airborne illnesses if properly fitted and airtight. While
health officials are not currently recommending n95 masks for the general public to combat the coronavirus outbreak, health
workers and those who are sick should consider wearing one. Here’s where you can easily order these masks online.
