High quality KN90 mask filter cotton is designed for efficient particulate matter filtration, and with excellent performance and quality, it is an effective barrier to protect respiratory health. This filter cotton adopts multi-layer composite structure, the outermost layer is water-resistant non-woven fabric, which can effectively prevent droplets and dust from entering the filter cotton interior; The middle layer is the core filter layer, which is made of electrostatic electret melt-blown cloth. Through the principle of electrostatic adsorption, the filtration efficiency of non-oily particles ≥0.3μm in diameter is as high as 90%, and it can easily filter pollutants such as pollen, dust and smoke. The innermost layer is a soft, skin-friendly non-woven fabric that fits the face and ensures comfort.
The filter cotton is cut accurately, fits closely with the main body of the mask, and is not easy to appear gaps, prevent pollutants from leaking, and ensure the protective effect. In addition, it has good air permeability, low respiratory resistance, will not cause respiratory burden to the user, and it is easy to wear for a long time.
In hazy weather, when outdoor travel, filter cotton can effectively filter harmful particles in the air; In the industrial production workshop, dust more environment, can protect workers from dust damage; In the face of flying dust during house decoration, it can also provide reliable protection for the user's respiratory system.
