As an economical and reusable type of mouthpiece, non-woven fabric has attracted increasing attention and use due to its excellent filtration effect and breathability. So, how effective is the filtration of non-woven masks? How to wear and clean correctly? Below, I will provide a detailed introduction.
The filtration effect of non-woven masks mainly depends on the selection of materials and the design of multi-layer structures. Non woven fabric material is a type of fiber sheet formed by suspending fibers in disordered air and undergoing processes such as high-temperature melting, spraying, and sintering. It has a special fiber structure that can effectively isolate the spread of large particles, small particles, and microorganisms.
For large particles such as dust and particulate matter, non-woven masks have better filtration effects. Usually, non-woven masks adopt a multi-layer design, with one layer being a material with coarser fibers, which can effectively prevent the entry of large particles. In addition, the high-density fiber structure of non-woven masks can also filter out small particulate matter such as PM2.5, bacteria, and viruses. According to relevant research, the filtration efficiency of non-woven masks can reach over 80% for particles with a diameter of approximately 0.3 microns.
However, although non-woven masks have good filtering effects, they cannot completely remove small particulate matter. Especially for smaller virus particles, non-woven fabric has a lower filtering effect and usually requires other effective protective measures, such as wearing a mask with higher filtering effect or maintaining good hand hygiene.
Proper wearing of non-woven masks is crucial for achieving their filtering effect. Firstly, make sure your hands are clean before wearing it, and you can use hand sanitizer or alcohol disinfectant to wash your hands. Next, pull apart the ear straps on both sides of the mask and wear them on the ears, completely covering the mouth and nose area with the mask. Then, gently press the curved part of the nose with both hands to make the mask tightly adhere to the nose, avoiding any gaps under the mask.
During the wearing process, it is important to avoid frequent contact with the external surface of the mask to prevent contamination from entering the mouth and nose. If you need to adjust the position of the mask, you should wash your hands with hand sanitizer or alcohol disinfectant before proceeding. In addition, wearing a mask should generally not exceed 4 hours, as various particulate matter and moisture will gradually accumulate inside the mask, and the filtering effect will be lost after prolonged use. Once the mouth is damp, a new mouth should be replaced immediately.
Proper cleaning of non-woven masks is the key to ensuring their continuous and effective filtration. Before cleaning, remove the mask and soak it in alcohol disinfectant or laundry detergent for about 5 minutes to kill any bacteria and viruses that may be present. Then, gently wash the mask with warm water, do not use brushes or other hard objects to scrub. Afterwards, dry the mask and avoid exposure to sunlight to prevent damage to the fiber structure and filtration effect. During the cleaning process, it is also necessary to ensure the cleanliness of hands by using hand sanitizer or alcohol disinfectant to wash hands.
In summary, non-woven fabric has a good filtering effect and can effectively isolate the spread of particulate matter and microorganisms. However, for smaller virus particles, their filtering ability is weaker and they need to be paired with other effective protective measures. In terms of wearing and cleaning, correct operation can play a good role in the effectiveness of masks and provide good protection. When choosing and using non-woven masks, everyone should strictly follow the relevant requirements to ensure their own and others’ safety.
