The gas mask is a highly effective personal protective equipment that can provide comprehensive protection for the respiratory system, eyes, and facial skin of the wearer. In light of the current global pandemic, the gas mask is also being considered for its potential ability to offer anti-virus protection. By filtering out harmful airborne particles, the gas mask can prevent the inhalation and spread of viruses, thereby reducing the risk of transmission. While further research is needed to fully understand the gas mask's potential as an anti-virus tool, it is clear that it has the potential to be a valuable addition to our arsenal in the fight against infectious diseases.
A gas mask comprises of two components: a mask and a canister. These two elements are crucial in enhancing the efficiency and effectiveness of the gas mask. By dividing them into separate parts, the gas mask becomes much more capable and efficient in protecting against hazardous gases.
The gas mask utilizes a pump-like mechanism to create a sealed environment, aided by a mouth and nose mask inside. This internal mask includes an inhalation valve piece, allowing controlled entry of gas. Additionally, an exhalation valve piece is present in the nose and mouth mask to facilitate the expulsion of exhaled gas. Through the manipulation of these valves, a unidirectional flow of gas is achieved.
During use, external gas first undergoes filtration before entering the mask. Subsequently, it passes through the inhalation valve piece within the mouth and nose mask, enabling the wearer to breathe. Meanwhile, any exhaled gas is effectively expelled through the exhaust valve. This process ensures that the gas mask's canister, which contains a poison countermeasure, serves as an effective defense against viruses and other harmful substances.

The canister's internal structure comprises four layers, namely a top-layer melt-blown fabric, followed by an activated carbon layer, then a chemical agent layer, and finally another melt-blown fabric layer at the bottom. The primary function of the melt-blown fabric layer is to filter out 3 micron dust particles, effectively preventing dust from entering. The activated carbon layer serves as the main filtration medium, utilizing its adsorption properties to absorb toxic gases. These gases are subsequently decomposed and purified by the chemical layer. This is the fundamental principle behind the canister's antiviral capability. The Haigu filter tank employs a robust 1.5 mm coal-type columnar activated carbon, ensuring resistance to crushing and featuring a highly porous structure. As a result, it can maximize the absorption of poisonous gases and effectively mitigate their harmful effects.
Gas masks rely on the principle of antivirus to protect individuals from inhaling harmful substances. This innovative technology has revolutionized personal protective equipment and has proven to be effective in shielding individuals from harmful toxins.
