Filter, through a variety of filtering material together, form a high level of filtering core material: silica gel mask mask core melt-blown knit, cotton and ordinary non-woven cloth, commonly used material is responsible for the three kinds of melt-blown fabric filter, clothing is responsible for the dust filter cleaning moistureproof and dustproof, ordinary non-woven is responsible for the ordinary barrier will be a variety of materials synthesis filter element, its protective effect is obvious, therefore, silica gel mask kernel is harmless to the environment.

Silica gel mask manufacturers in the production of silica gel mask before, need to find a kind of important material silicone mask core, at the same time also want to understand it, and see if it's environmentally friendly "core has been in the industry of environmental protection silicone mask get affirmation is a new generation of environmental protection filtration material, has moisture-proof breathable flexible light weight, no combustion can decompose non-toxic non-irritating cheap recycled characteristics such as silica gel mask generally exists in the inner core of the mouth of the silica gel mask nose filter layer, and a filter cleaning tide resistance strong stable quality dust resistance strong long life and other characteristics.
