This electrostatic filter cotton is made from special electrostatic fibers using a needle-punching process. Utilizing the electrostatic charge transfer mechanism between fibers, positive and negative charges are transferred to the fiber surface and outer layer, respectively. Because the fibers used in this product are highly electroinert, the positive and negative charges are stably retained on the fibers, without escaping or neutralizing.

Compared to traditional filter media that rely on interception filtration, this product offers lower resistance and higher filtration efficiency. The needle-punching process ensures a large dust holding capacity, effectively extending the filter media's lifespan and reducing user costs. Advantages:

1. Higher filtration efficiency. This is due to the electrostatic adsorption mechanism.

2. Lower resistance. This reduces the power consumption of fans and motors. This is due to the needle-punching process.

3. Longer service life and lower operating costs. High dust holding capacity.

4. It captures submicron dust more stably and for a longer period of time than ordinary filter media.

5. It is easy to combine, fold, pleat, shape, and bond with other materials.

 

This product is widely used in mask products, air conditioners, air purifiers, fresh air systems, medical filters, vacuum cleaners, and bacterial filters.
