These nominal 8 x 10 inch filters are typically used with high volume air samplers as specified in 40 CFR Part 50, Appendixes B (TSP) and J (PM10).
Appendix B - Reference Method for the Determination of Suspended Particulate Matter in the Atmosphere (High-Volume Method) specifies glass fiber or other relatively inert, nonhygroscopic material with a collection efficiency of 99% minimum as measured by the DOP test (ASTM-2986) for particles of 0.3 μm diameter.

Section 2.11 - Reference Method for the Determination of Particulate Matter as PM10 in the Atmosphere (High-Volume PM10 Sampler Method) of U.S. EPAs Quality Assurance Handbook states that the microquartz fiber filter is currently the only commercially available filter that satisfies all criteria specified in 40 CFR 50, Appendix J.
