Everyone should have heard of disposable dust masks. Some people have also worn them, but few people really know the maintenance methods and cleaning methods of disposable dust masks. So today, the small masks of disposable masks are simple for the majority of users. Under the introduction, I hope to help everyone.

Maintenance method of disposable dust mask: The outer layer of the disposable 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 disposable dust mask cannot be used alternately on both sides, otherwise The dirt contaminated on the outer layer will be inhaled into the human body when it is directly attached to the face, and become a source of infection. When the mask is not worn, it should be folded into a clean envelope and folded close to the face of the nose and mouth. Don't just put it in your pocket or hang it around your neck; if the disposable dust mask is exhaled by the hot air or saliva, the 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.

How to clean the disposable dust mask: Gently lick the gauze mask with warm water and soap. The bowl mask can be lightly 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, you will lose the anti-stopping effect; put the cleaned mask in 2% peracetic acid solution for 30 minutes or boil in boiling water. Steam for 15 minutes in a steamer for 20 minutes, then allow to dry. This method is suitable for gauze masks and bowl-shaped masks; before re-use, you should carefully check whether the masks and masks are still intact. For gauze masks and masks, you can take a light-transparent inspection method, that is, take the light before looking at the light to see if there is any The obvious light spot, the light transmittance of the middle part and the edge part are the same, 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.
