The Outer Layer Of The Disposable Mask Often Accumulates A Lot Of Dust In The Outside Air.

- Apr 24, 2019-

The outer layer of the disposable 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 cannot be used alternately, otherwise the dirt contaminated by the outer layer will be directly Inhaled into the body when it is close to the face, and becomes a source of infection. When the mask is not worn, it should be folded into a clean envelope and folded in a side that fits snugly against the nose and mouth. Do not hang it in the pocket or hang it around your neck.

If the disposable mask is wetted by the exhaled heat or saliva, its effect of blocking the bacteria will be greatly reduced. Therefore, it is best to prepare a few masks for normal replacement, and should be changed once a day. Wash with boiling water for 5 minutes.

The specific practice of disposable mask cleaning is:

1. Cleaning. Gently lick the gauze mask with warm water and soap. The bowl-shaped mask can be gently brushed with a soft brush and then washed with water. Please note that you should never use force, because if the latitude and longitude gap of the gauze is too large, the effect of anti-stopping droplets will be lost.

2. Disinfection. Place the cleaned mask in a 2% peracetic acid solution for 30 minutes or boil in boiling water for 20 minutes or in a steamer for 15 minutes, then allow to dry. This method is suitable for gauze masks and bowl masks.

3. Check. Before using it again, you should carefully check whether the mask and mask are still intact. For gauze masks and masks, you can take a light-transparent inspection method, that is, take the light before the light to see if there is any obvious light spot, and the middle part and the edge part are transparent. Is the rate consistent? If there is any doubt, it is necessary to replace it with a new one. In any case, masks and masks are generally updated after 3 to 7 washes, and masks of exceptional quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to the regular replacement of the activated carbon interlayer. If the activated carbon interlayer is not replaceable, it should be replaced after 7 to 14 days. This mask can not be used after cleaning.
