What are the characteristics of the filter non-woven fabric in the air purifier?

Non-woven fabric filter cotton can also be divided according to the different efficiency of filtration: primary filter cotton, filter cotton.

The pre-filter screen of the air purifier adopts non-woven coarse effect filter cotton, which has good air permeability, strong sealing, and no leakage.  It is mainly used in primary filtration, can effectively remove large dust, mold, and animal hair, is clean and visible, and play a role in protecting other filters.

Filter non-woven cloth, also known as non-woven cloth, is made of polypropylene or polyester as raw material, with melt-spray, acupuncture, spun-bond, and other processes, made by multiple processes, it has stable performance, non-toxic, no odor is a new generation of environmental protection materials.  Non-woven fabric for filtration is characterized by large dust capacity, no combustion support, long service life, economic and durability, and it has strong fouling capacity, a large flow rate, high-pressure resistance, strong corrosion-resistance, recycling and reuse, wide application range, etc.  Non-woven fabric is also the use of the first filter materials, mature technology, low production cost, in recent years because of the continuous development of technology, composite non-woven fabric greatly improves the image of non-woven fabric cheap low grade, in the effectiveness has been able to reach the sub-high efficiency.  At the same time, the compound non-woven cloth filter material can also be used for air cleanliness relative to the request of high-place filtration.
