kn95 mask filter membrane filtration efficiency

With the intensification of water pollution, people are becoming more and more concerned about the quality of drinking water.

Experiments have shown that the kn95 mask filter membrane can remove slightly toxic by-products, heavy metals, natural organic matter and hardness produced during the disinfection process, and is a very good filter material.

The diameter of the new coronavirus is about 60-140nm (0.06~0.14 microns).

Medical surgical masks have only a 30% filtration efficiency for 0.3 micron particles. However, since viruses, bacteria and other pathogens cannot exist alone in the air and must be attached to particles such as dust and droplets, they can also provide effective virus protection. protection.

The 0.3 micron particle filtration efficiency of N95 masks can reach more than 95%, and they can better fit the human face, so they can play a better virus prevention role.

The kn95 mask filter membrane has high-density micropores, which is refreshing and breathable. The membrane has excellent properties of hydrophobic micropores and non-absorbent moisture. It is not easy to accumulate water vapor and 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.

It is a high-tech enterprise specializing in the research and development, production and sales of kn95 mask filter membranes. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we produce The products are produced using imported raw materials, with finer molecular weight, cleaner quality and better uniformity.

And we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
