The misconception of choosing dust masks is a common mistake among many people

The core of wearing a fangdun dust mask is to use it in a standardized manner. If you fall into a usage error, even if you choose the right mask, it will be difficult to achieve the protective effect. These four common misconceptions need to be avoided in daily use.

Misconception one is improper wearing, which can easily lead to air leakage without being noticed.

Behaviors such as unadjusted nose clips, improper headband tension, and incomplete mask coverage of the mouth, nose, and jaw can significantly reduce the protective effect. The correct approach is to shave your beard and remove your facial accessories before wearing. First, tighten the headband to ensure a snug fit, press the nose clip to fit the curve of the nose bridge, and confirm that the mask fully covers the mouth, nose, and chin. After wearing, perform an air tightness check to prevent any leakage issues.

The second misconception is that masks have exceeded their service life.

Many people believe that masks can be used continuously without getting dirty or broken, but in fact, the filter material of dust masks will be blocked by dust as they are used, and the filtration efficiency will gradually decrease. It will also adsorb bacteria and pollutants, which can easily cause respiratory discomfort. Replacement should be based on the scenario and status: it can be worn for 1-2 days during short daily commutes, and it is recommended to replace it every day for industrial dust environments. For high concentration dust environments, it is recommended to replace it every half a day; As long as there is an increase in respiratory resistance, dirty or damaged mask body, odor, or contact with polluted environment, it should be replaced immediately.

Misconception three is to wear adult masks for children.

Children's face shape is relatively small, and adult masks cannot guarantee tightness. Dust is prone to leak through gaps, and respiratory resistance and size are not suitable. Long term wearing can affect children's breathing and even cause discomfort. Children should choose specialized dust masks, which are more suitable for their size and breathing resistance, and made of materials that are more skin friendly. Parents should assist in adjusting and monitoring the entire process when wearing them. If discomfort such as suffocation and dizziness occurs, the mask should be removed immediately.

Misconception four is the misconception that sterilized masks have better protective effects.

In fact, sterilization only refers to the sterility of the mask itself before it is opened, and is not related to filtration efficiency. The core of the protective effect is the filtration material and the implementation standards. After wearing the mask, it will quickly absorb bacteria and dust, and its sterilization properties will quickly disappear. When making a purchase, there is no need to deliberately pursue sterilization properties. Focus on the execution standards, protection level, and sealing degree; Wash hands before and after wearing, clean and dry reusable masks, and discard masks that come into contact with polluted environments at once.
