Adult masks dustproof efficiency:
The dustproof efficiency of adult masks is based on their shielding effectiveness 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. The dustproof principle of gauze into a population cover is mechanical filtering, that is, when dust hits the gauze, through large layers of barriers, some large dust particles will be blocked by sand cloth. For some fine dust, especially dust smaller than 2.5 microns, the adult mask will pass through the gauze mesh and enter the respiratory system. The dust-proof cover is composed of filter material, activated carbon fiber felt or non-woven fabric. Respirable dust less than 2.5 microns is blocked as the filter material passes to filter the air.
Adult Mask Closeness
The anti-side leakage design of the Adult 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 Adult 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 wearAdult Masks in the correct steps.
Adult Mask Comfortable to wear
In this way, workers will be willing to wear Adult Mask 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 Adult 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.
Adult Mask Filter material introduction：
Adult MaskMask filter material
The structure of the gauze mask is poorly adhered to the human face. Many fine particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. Its filter material is generally some mechanical fabric. This filter The only way to achieve high dust blocking efficiency is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel great resistance to breathing and feel uncomfortable. And the non-woven fabric treated with static electricity can not only block large dust particles, but also the electrostatic charge attached to its surface can attract fine dust by electrostatic attraction, and achieve high dust blocking efficiency. The thickness of the filter material is very thin, which greatly reduces the user's breathing resistance and feels comfortable, thereby achieving the three necessary conditions of the good filter material we mentioned earlier. With good filter material and scientifically designed mask structure, it constitutes an efficient and high-quality mask.
Fit effect of Adult Mask
Adult Masks must be the right size and worn in the correct way to be effective. Masks on the market are generally divided into rectangular and cup-shaped. A rectangular mask must have at least three layers of paper to protect it. The user must press the wire on the mask against the bridge of the nose, and then spread the entire mask along the bridge of the nose to exert its effectiveness. Children can wear rectangular surgical masks, because they have no fixed shape, and if they are tied well, they can fit on the child's face. For cup masks, make sure the mask is dense enough to stick to the face, and the exhaled air will not leak out to be effective. When wearing a cup-shaped mask, cover the mask with both hands and try to blow. Check if there is air leaking from the edge of the mask. If the mask is not tight, reposition it before wearing it.
