The European standard divides particulate protection filter materials into two types: solid particle protection and liquid particle protection, which are tested and classified by sodium chloride and DOP aerosol respectively.
Qualified solid particle protective filter materials can be divided into three types according to the tested particle penetration rate. Among them, the filtration efficiency of the ffp3 mask filter material is good.
The outer layer of FFP2 type masks often accumulates a lot of dust, bacteria and other contaminants in the outside air, while the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the outer layer will be contaminated with pollutants. When the object is directly attached to the face, it is inhaled into the human body and becomes a source of infection.
The filtration efficiency of ffp3 mask filter material for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception. The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
It is a high-tech enterprise focusing on the R&D, production and sales of ffp3 mask filter materials. 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 all 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.
