It can be considered based on five factors such as reference mask material, mask accessory filter box, gas mask type, mask certification and gas mask process details:

1. Mask material: (rubber, silicone)

The traditional gas mask material is rubber, but the rubber material is easy to aging, a few people with sensitive skin wear it, easy to allergy.

Now the market upgraded silicone material, it has better comfort, softer facial fit, good oil resistance and not easy to aging.

2. Filter box (or canister): (single and double filter box)

Gas masks need to be equipped with filter boxes or canisters, which are usually categorized into single and double filter boxes. The advantage of double filter box is that it reduces the breathing resistance of the wearer and the filtering effect is more obvious. The advantage of a single filter box is that there are fewer filters, less weight and less weight on the wearer's head. It should be reminded here that the filter cartridge and the filter wool are consumables and need to be replaced regularly, so be sure to pay attention to the use cycle of the filter cartridge or the filter wool.

3. Types of Gas Masks: (Half Masks and Full Masks)

Half masks can only protect the nose and mouth, while full masks can protect the whole face. It is safer to wear a mask if the environment in which the mask is used is sprayed with a liquid or toxic gas that is irritating to the skin. For general protection from toxic gases and if there are no liquid splashes, you can use a half mask because the field of view of a half mask is wider than that of a full mask.

4. Gas mask certification:

Qualified protective products must be certified by authoritative organizations to ensure the real safety of users. For example, domestic gas masks need to pass China's LA certification; while foreign gas masks are usually certified by the National Institute of Occupational Safety and Health (NIOSH), Europe's CE certification, Japan's MHLW certification, and Korea's KMOL certification.

5. Gas mask details:

5.1 Thickness of head frame/headband: usually, the head is wider and more comfortable because the force area attached to the head is larger and does not put pressure on the head;

5.2 Width of end-face mating section: the wider the mating section, the better the seal and the better the gas protection;

5.3 Overall appearance: the surface is smooth and not rough, and will not cause damage to the skin;

5.4 Breathing port design: the design of the breathing port is superior to the horizontal design, because the downward design can discharge hot and humid exhalation without affecting the vision, the breathing valve piece is not easy to contaminate, easier to clean;

5.5 Production process: disposable compression molding gas mask is stronger and has a longer service life than decomposition gas mask;

5.6 Nose and mouth mask odor: obvious material odor easily lead to human respiratory malpractice, seriously cause skin disease and other skin diseases.
