2. Disposable masks
The main material of disposable masks is non-woven fabric plus a layer of filter cloth, which has a small effect on dust and some PM2.5 and avian influenza viruses, but it is blocked by fine particles such as PM2.5 and avian influenza viruses The role is also limited.
3. Cotton mask + ordinary filter mask
There is no more popular PM2.5 mask on the market than this one. A layer of cotton cloth plus a common non-woven filter is superior to the first two in terms of practicality and visual aesthetics.
4. Industrial protective masks
The main material of N95 masks is imitation cotton cloth plus special filter cotton for masks, and the overall sealing of the masks is good for blocking and filtering PM2.5 and avian influenza viruses, and it is protected against industrial dust and toxic gas The effect is better and the recognition is relatively high.
