M95303

Description

➊ Suitable for ordinary daily protective masks for civilian use, non-medical. ➋ Non-woven fabric and hot-air cotton block large particles and dust. ➌ The filter layer uses a high-strength ePTFE microporous film composite material and uses its high-filtering and low-resistance physical structure to filter fine particles in the air, which has a more stable filtration efficiency. ➍ The inner layer is made of soft non-woven fabric, which is skin-friendly and comfortable. ➎ Three-dimensional cutting, retaining a large cavity, fitting the facial curve, suitable for a variety of face shapes. ➏ Soft and elastic adjustment buckle，no tightness on the ears. ➐ Individually sealed packaging，clean and hygienic.

evolution OF FACE MASKS

In the function of preventing airborne bacteria, face masks have undergone three important stages of development: 1st Generation Gauze mask , 2nd Generation Melt-blown fabric mask, 3rd reusable nano microporous filter-film mask.

1

First generation Gauze mask

Made from gauze material. The large aperture can only intercept large particles in the air but can’t block PM2.5, the protection effect is limited, the wearing feel is not comfortable, so it is an outdated product.

2

Second generation Melt-blown fabric mask

Made from non-woven fabric. The aperture size can intercept the middle to large particles in the air and absorb the dust by the electrostatic effect. It is the mainstream mask at present. (However, the filtration efficiency will be significantly reduced after a few hours due to vapor condensation. The type of mask cannot be washed or disinfected.)

3

Third Generation Microporous filter-film M2 mask

Made from the technological microporous film. The aperture size is tiny. Utilizing the physical principles to filter particles in the air，the type of face mask，represents the development direction of future protection. (This new filter-film can be gently washed and disinfected, it is non-disposable in usage.）

Outer layer

PP non-woven fabric, rough material, light transmission

Filter layer

No filter layer

Inner layer

PP non-woven fabric, thin and non-hygroscopic

Outer layer

PP non-woven fabric, waterproof, breathable, not easy to wash

Filter layer

PP melt-blown non-woven fabric, electrostatic adsorption and filtration, it may adsorb water vapor after wearing for 4 hours, and the filtration performance is greatly reduced

Inner layer

PP non-woven fabric, not suitable for long-term wear, easy to form water vapor

Outer layer

Breathable outer fabric, anti-wrinkle, easy to care, breathable, washable

Filter layer

Nano microporous filter-film,Physical filtration, can be disinfected multiple times

Inner layer

Pure cotton skin-friendly fabric, moisture-absorbing and breathable, no irritation

The application of new type NANO microporous fiber-film mask in protective use

We have developed a new generation of filter materials that can be used as masks， expended polytetrafluoroethylene ，as known as ePTFE， which is a high over-rate and low-resistance microporous film. The film has good chemical stability, can withstand high-temperature boiling water, 75% alcohol and 84 disinfectant and other disinfection, filtration efficiency remains high.
