At present, in industries such as industry and coal mines, dust masks have become a standard occupational labor insurance product. With the popularity of masks, there is an urgent need to popularize knowledge about the cleaning and maintenance of industrial dust masks.
Can industrial dust masks be washed in water?
Dust masks are divided into disposable masks, maintenance-free masks, reusable masks, etc. Different industrial dust masks can be washed with water, but some cannot. Professional dust masks from brands such as 3M are non-washable and maintenance-free masks. Once this kind of dust mask is cleaned with water, it will destroy the filter layer, such as electrostatic filter cotton, thereby weakening its protective effect.


The gauze mask can be reused after cleaning, but the protective effect of the gauze mask is relatively weak and cannot effectively protect the user in a dusty environment. The half-mask dust mask/gas mask can be cleaned with water, but the filter material in the filter tank cannot be cleaned with water. If the effect diminishes, it must be replaced.


Cleaning method of industrial dust mask:
1. Clean
First wipe the gauze mask gently with warm water and soap. You can gently clean the bowl-shaped mask with a soft brush dipped in detergent, and then rinse with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, the anti-dripping effect will be lost.
2. Disinfection
Soak the cleaned mask in a 2% peracetic acid solution for 30 minutes, or boil it in boiling water for 20 minutes, or steam it in a steamer for 15 minutes, and then dry it for later use. This method is suitable for gauze masks and bowl-shaped masks.
3. Check
Before using it again, carefully check whether the mask and face shield are still in good condition. For gauze masks and face masks, you can use the light transmission method, that is, use the light in front of the lamp to see if there are obvious spots. The middle part and the edge part are transparent. Is the rate consistent? If in doubt, please replace it with a new one. In any case, masks and masks are usually updated after cleaning 3 to 7 times, and masks of particularly good quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to regularly replace the activated carbon interlayer. If the activated carbon middle layer cannot be replaced, it must be replaced after 7 to 14 days. You cannot use this type of mask again after cleaning.
