In 2020, with the outbreak of the new coronavirus pneumonia around the world, masks, which were previously inconspicuous, have become the most scarce supplies in various countries.

The kn95 mask filter membrane is one of the core materials for making masks.

NIOSH’s evaluation method is to use NaCL (sodium chloride) particles for testing. Under the specified temperature and air flow, the filtration effect on particles of specified diameter and weight is tested, and then based on the filtration effect of 0.3 microns (aggregated average diameter 0.3 μm ) to obtain the filtration efficiency. N95 means that 95% of 0.3 micron particles are blocked.

The kn95 mask filter membrane is mainly due to its use of materials with smaller fiber diameters compared with traditional masks.

Generally speaking, the fiber diameter of the ordinary non-woven material used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE membrane is between 100 and 200 nanometers, which is much smaller than the above diameter. Therefore, it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.

It is an environmentally friendly material manufacturer specializing in R&D, production and sales of kn95 mask filter membranes.

Our company is different from other manufacturers.

Our company can customize according to user’s requirements.

The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .

The company can provide samples and arrange sales staff to provide door-to-door service if there are other requirements.

You are welcome to come to the company for inspection or enter the store to consult us at any time.
