Filter masks are the most widely used in daily work. The selection methods and conditions of use of these masks are described in detail below. The structure of a filtering mask should be divided into two parts, one is the main body of the mask, which can be simply understood as a shelf of the mask; the other is the filter material part, including filter cotton for dust prevention and chemical filtering for antivirus Boxes etc. Therefore, for the selection and use of filter masks, some products produced by Guangjia provide you with the following convenience, that is, you can use the same type of mask body. When dust protection is required in a dust working environment, match it with the corresponding Filter cotton, so you wear a dust mask; when you need to perform anti-virus in a toxic environment, replace the filter cotton and the corresponding chemical filter box on the device, so that it has become a anti-virus mask or according to Your work needs provide you with more combinations.

Brief introduction of the filter material of the mask

The filter materials of protective masks are mainly divided into two categories, namely dust-proof and anti-virus. The role is to absorb harmful aerosols, including dust, smoke, mist, toxic gas and toxic vapor, etc., through the filter material, blocking it from being inhaled by people.

Use of masks

In general, the mask must be of a suitable size and the wearing method must be correct for the mask to be effective. Masks on the market are generally divided into two types, rectangular and cup-shaped. The rectangular mask must have at least three layers of paper structure in order to have a protective effect. The user needs to press the wire on the mask against the bridge of the nose, and then spread the entire mask along the bridge of the nose in order to exert the effect. Let the child wear a rectangular surgical mask because it has no fixed shape, and if it is properly tied, it can fit the child's face. Cup-shaped masks must ensure that the masks have sufficient density after they are attached to the face, so that the air will not leak out when inhaled. When wearing a cup-shaped mask, you can cover your mask with both hands and try to blow air. Check whether there is air leakage from the edge of the mask. If the mask is not tight, you must readjust the position and then wear it.

When do you need to change your mask

Dust-proof filter cotton, when the mask is in close contact with the user's face, when the user feels a lot of breathing resistance, it means that the filter cotton has been filled with dust particles and should be replaced with a new one.

3. Damaged mask

4. Anti-virus filter box, the mask and the door of the user are in good contact, when the user smells of toxic substances, it should be replaced with a new mask should not be temporarily worn from the perspective of human physiological structure, due to human Nasal mucosa blood circulation is very strong.
