These high purity QM-B quartz fibre filters are designed for use in specific air monitoring applications.
QM-B filters are similar to QM-A quartz fibre filters, which are recommended more commonly for air testing applications. By comparison, QM-B is approximately twice as heavy, twice as thick and offers slower flow rates. Because of these characteristics, QM-B can be used in air monitoring applications requiring increased strength or durability.
