●Deep gradient structure woven with special technology, allowing the pore size of the filter material to gradually decrease from large to small, thereby increasing the filter bag's capacity for holding impurities.

●Compared to standard filters of the same precision, ultra-long filter bags are about twice as thick, and their online lifespan can be 1.6 to 2 times longer than standard filter bags.

● Materials available include polyester and polypropylene.

● Filter precision ranges from 1 to 100 micrometers available

All filter bags meet FDA certification.
