<P> Quartz fiber filter paper is high resistance chemical, does not absorb NOx and SOx dioxides, unaffected by humidity and easily sterilized . Thus, it is mostly use for air pollution analysis . </P> <P> PTFE filter has wide operating temperature (- 120 ° C ~ 260 ° C) with high air permeability . The resistance of high temperature makes PTFE filter paper autoclavable . It is often use for filter hot oils, strong solvents and collecting airborne particulates . </P> <P> Engine oil is filtered to remove impurities . Filtration of oil is normally done with volume filtration . Filter papers for lubrication oils are impregnated to resist high temperatures . </P> <P> Tea bags are made from abacá fibers, a very thin and long fiber manilla hemp . Often the paper is augmented with a minor portion of synthetic fibers . The bag paper is very porous and thin and has high wet strength . </P>
