There are many types of mask filters on the market now, which is really confusing.
This includes materials such as PTFE nanomask filters, which have become a weapon for medical staff to fight the epidemic, a shield to protect the health of the public, and a guarantee for enterprises to resume work and production in an orderly manner.
The anti-SARS virus medical mask adopts a multi-layer non-woven fiber mesh composite form, which is composed of three major parts: a surface anti-moisture layer, a middle high-efficiency filtration and adsorption layer, and an inner layer of skin-friendly material. It has a skeleton-free arch structure. .
The middle layer of high-efficiency filter material adopts a special melt-blown non-woven process. The polymer is drawn by high-pressure and high-heat air into ultra-fine fibers with an average diameter of less than 3 μm. The fibers in the filter material are randomly arranged and interleaved to form a multi-layered structure. Fiber filter layer with curved channels.
The ptfe nano mask filter membrane has high-density micropores, which is refreshing and breathable. The film has excellent properties of micropores, hydrophobicity and non-moisture absorption. Water vapor is not easy to accumulate, and it can quickly wick away moisture, keeping it fresh and breathable for a long time.
Due to the different materials of masks, the effects are also different. Non-woven fabrics and ordinary cotton fabrics will attenuate with filtration time, while masks made of ptfe film material are long-lasting and stable, can be self-cleaned, have the same resistance, and filter It is also more efficient than ordinary masks.
