Maintenance Method Of Dust Face Mask

Abstract: Can dust masks be washed with water? Activated carbon adsorption dust masks cannot be washed with water, what about other dust masks? This article will introduce you in detail the maintenance and cleaning methods of dust masks.

Maintenance method of Dust Mask

1. The outer layer of the dust mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides of the dust mask cannot be used alternately, otherwise the outer layer will be contaminated The dirt is inhaled into the human body when it is directly close to the face, and becomes the source of infection.

2. When the mask is not worn, it should be folded and put into a clean envelope, and the one-side that is close to the nose and mouth should be folded inward. Do not stuff it into the C bag or hang it around your neck.

3. If the dust mask is wet with exhaled heat or saliva, its function of blocking germs will be greatly reduced. Therefore, it is usually best to prepare a few more masks for replacement, which should be changed and washed once a day. When washing, it should be scalded with boiling water for 5 minutes.

How to clean the dust mask
Dust masks should be cleaned and disinfected every day. Both gauze masks and air filter masks can be disinfected by heating. The specific method is:
1. Cleaning
Gently rub the gauze mask with warm water and soap first, the bowl-shaped mask can be gently brushed with a soft brush dipped in detergent, and then washed with clean water. Please note, do not use

Knead vigorously, because if the warp and weft gap of the gauze is too large, it will lose the function of preventing droplets.

2. Disinfection
Soak the cleaned mask in a 2% peroxy Z acid solution for 30 minutes or boil it in boiling water for 20 minutes or 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 mask and the mask are still in good condition. For the gauze mask and the mask, the light transmission inspection method can be adopted, that is, take it to the light to see if there are obvious light spots, and the middle part and the edge part are transparent. The rate is not the same, if in doubt replace it with a new one. In any case, masks and masks are generally renewed after 3 to 7 times of cleaning, and masks of particularly good quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to replacing the activated carbon interlayer regularly. If the activated carbon interlayer is not replaceable, it should be replaced after 7 to 14 days. This kind of mask cannot be cleaned and reused.
