silicone mask has been developed in the early years for anti-virus and anti fog, and the selection of silicone mask has a relatively long service life, soft and comfortable. Long time wearing, not easy to cause allergic reaction. However, silicone materials are also divided into different degrees of hardness and softness. Masks with high hardness are easy to cause facial indentation, while low hardness masks may not be worn firmly and easy to cause air leakage.

According to our understanding, the silicone mask and silicone mask products on the market at present are only made of silica gel material for the part pasted on the face, while the material used for the main part is Plastic, which is filtered through the filter box or filter sheet. Silicone products have good skin affinity, non-toxic, tasteless, soft and comfortable, not aging and hardening, easy to clean, durable and deformation, repeated use can still ensure good adhesion, sealing and other advantages.

However, if the filtration part of silicone rubber mask and silica gel mask is not multi-layer filtration at the same time, filter cotton is still used, such as synthetic fiber filter cotton, non-woven fabric filter cotton, glass fiber filter cotton, activated carbon filter cotton, etc, One or more kinds of filter cotton and one or more layers of filter cotton are used for air filtration in order to prevent the new coronavirus from invading the human body. However, the actual effect is quite different. Therefore, whether it is a silicone mask or a common mask, the important problem is still the filter element problem in the middle.
