Supply KN95 FFP2 Mask

Supply High Quality KN95 FFP2 Mask
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, it passes through layers of barriers to block some large particles of dust 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.

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 should be cleaned and disinfected daily. Both gauze masks and air filter masks can be disinfected by heating. The specific approach is:
1. Cleaning. Gently rub the gauze mask with warm water and soap first. The bowl-shaped mask can be gently cleaned with a soft brush dipped in detergent, and then washed with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, it will lose the effect of preventing droplets.
2. Disinfection. Soak the cleaned face mask in a 2% peroxyacetic acid solution for 30 minutes or cook in boiling water for 20 minutes or put it in a steamer for 15 minutes, then dry it for later use. This method is suitable for gauze masks and bowl masks.
3. Check. Before using it again, you should carefully check whether the masks and masks are still intact. For the gauze masks and masks, you can use the light transmission inspection method. Is the rate consistent? If in doubt, replace it with a new one. In any case, masks and masks are generally updated after 3 to 7 times of cleaning, and masks of particularly good quality can be washed 10 times. Activated carbon adsorption masks should be replaced regularly with activated carbon interlayers. If activated carbon interlayers are not replaceable, they must be replaced after 7 to 14 days. This type of mask cannot be reused after cleaning.
