Background
The common inlet mask or the so-called medical mask, such as 3M N95 (Non-reactive to oil dust) mask, works on the principle that static electricity is applied to Non-woven fabrics, and dust particles with static electricity in the air are absorbed by the principle of electrostatic adsorption. The bacteria and viruses are not always charged electrostatically and can be adsorbed. Because the non-woven fabrics aperture is big, unable effective physics separation dust, following this gauze mask meets after respiratory moisture, the static on the harmless cloth disappears gradually and loses the function of its adsorption band static dust, causes the protection inefficacy. Such masks based on the principle of electrostatic adsorption cannot be washed with water or alcohol, and the non-woven fabric with static electricity loses static electricity when contacting water or alcohol, thereby losing its adsorption function, so that it can be used only once for a short time, and is also called disposable masks. The protective effect is very limited, the storage period is up to 6 months, the expired static electricity disappears, the mask fails due to no adsorption function, and therefore, hospitals dare not to prepare too many masks.
Similarly, the mask containing the activated carbon structure needs to be packaged in vacuum, and the mask loses the due protective function of absorbing chemical substances due to the saturated adsorption of the activated carbon after the mask is opened.
