High-volume filter

From Glossary of Meteorology



high-volume filter[edit | edit source]

Instrument for measuring total particulate matter in the atmosphere.

Air is drawn into the instrument at a high flow rate of 1–2 m3 min-1 and passes through a filter bed that traps particles. The high-volume filter is the current standard recommended by the U.S. Environmental Protection Agency for measurement of particulate matter in the atmosphere.


  1. A gaseous envelope gravitationally bound to a celestial body (e.g., a planet, its satellite, or a star).
