1: fiber filter cotton, under the general filtration conditions can replace all non-woven fabrics and glass fiber cotton. It is an emerging filter material that has just come out, and it is also the main development direction of air and other filter materials in the future. His advantages are low resistance, light weight, large capacity, environmental protection (can be incinerated) and other characteristics, but the price is relatively high.
2: non-woven filter cotton, the process is made of melt-blown, needling, spunbonded and other multi-process, compared with other filter materials, relatively stable quality, large dust tolerance, and strong moisture resistance, economic and durable advantages. Non-woven filter cotton is also the earliest application of filter materials, relatively low production costs.
3: glass fiber filter cotton, he is mainly made of glass fiber of different thickness and length through special processing technology. Glass fiber is characterized by stable performance, high temperature resistance, high efficiency, long service life and so on. Widely used in the general ventilation system of the initial effect filter, high temperature filter and high efficiency filter, the air filtration requirements of high places and environments.
4: Activated carbon filter cotton, as we all know, many home straight drinking machine, basically used this. Its characteristic is that it can remove odors from the air. Because the role of activated carbon itself is to remove the odor, the filtration efficiency is not emphasized. The price of filter cotton is also moderate, not too expensive and not cheap
