What mistakes should I avoid when buying a mask?
1.Can disposable non-woven masks and common activated carbon masks effectively isolate smog?
Actually, it can't. The structure of these masks determines that they cannot form an effective seal around the mouth and nose, and the non-woven fabric material is not born for dust and haze. Activated carbon has little effect on blocking fine particles.
2. Is the bigger the mask brand and the higher price, the better the effect?
This is certainly not necessary. Not every big foreign brand has products that are more suitable for our domestic market, and for others it may not be for you. The effect of the face mask is not necessarily related to the price.
3. Is the mask protection level higher?
actually not. A high level of protection means greater resistance to breathing and a much lower level of comfort. Serious or even breathing difficulties, so we still need to buy and wear masks according to our own needs, and do not blindly pursue high-grade masks. It is generally sufficient to wear anti-fog masks with filtering efficiency higher than 90% in ordinary fog and haze weather.
