Used for months, easy to carry and clean.

Eco-friendly materials are moisture-proof, non-toxic, non-toxic, soft and flexible.

A unique three-layer filter, non-woven design, can prevent pathogens (bacteria, virus), dust, car exhaust, pollen, etc.

The closest fit to your face. Elastic earrings are easy to wear without putting pressure on the ears.

Public places include offices, shopping malls, airports and other places where people can congregate. Good hygiene and washing of hands are essential to spreading the disease.

A face mask is a sanitary product, generally refers to a device worn on the nose and nose to filter the air entering the nose and nose to prevent harmful gases, odors, and droplets from entering and exiting the wearer's nose and nose, made of gauze or paper.

Masks have a certain filtering effect on the air entering the lungs. When respiratory infections are prevalent, wearing masks has a very good effect when working in a polluted environment such as dust.

construction of disposable surgical masks
 

 
Compared with traditional meltblown masks
1. The filtration efficiency of PTFE for air bacteria and PM2.5 particles can reach more than 95%, which meets the filtration standards of KN95 masks.
2. PTFE membrane is naturally hydrophobic. The filtering mechanism is physical mechanical retention (pore size interception method), which will not reduce the retention rate due to exhaled moisture, which is more stable and durable than the electrostatic adsorption protection of ordinary meltblown cloth masks.
 

Features of disposable surgical masks

The core material of the film mask is a PTFE nano film, and the diameter of the film fiber is between 100 and 200 nanometers.

The film mask made of this material has the following three characteristics:

1. Higher blocking efficiency. The main reason is that the fiber diameter of the material used is smaller than that of traditional materials (the fiber diameter of non-woven materials used in traditional masks is more than 1000 nanometers), which can more effectively block PM2.5 in the air (aerodynamic equivalent diameter is 2500 nanometers or less Particulate matter), and effectively reduce the concentration of bacteria and viruses in the air;

2. Longer life. The reason is that it uses physical principles to isolate air pollutants and is more durable. (The non-woven fabric used in traditional masks has a large fiber diameter and needs to rely on electrostatic adsorption of particulate matter. Static electricity is affected by temperature and humidity in the environment in a short time. Invalid, so it can only be used once);

3. Breathe more easily and freely when worn. The wearing comfort of the mask is mainly determined by the breathability and moisture permeability of the mask. The film mask has a higher air permeability due to its material characteristics of a high uniform hole distribution rate; coupled with the moisture-proof and moisture-permeable characteristics of the film material, it can bring users a more comfortable breathing experience.
