For years, air filtration engineers have worked with a simple rule of thumb: if top-tier dust holding capacity (DHC) is the priority,
A filter that tests as ePM1 on the bench is expected to keep performing as ePM1 in the field. For filters that
MERV (Minimum Efficiency Reporting Value) ratings remain the primary benchmark for air filter performance, yet they address a narrower scope than many
The American Filtration & Separations Society (AFS) is pleased to welcome Camfilas its newest corporate member, adding one of the world’s leading
This Introduction to Air/Gas Filtration course is to introduce the basics of air/gas filtration. It provides fundamental information on air filtration principles, filter media and filters for air filtration applications, selected examples of applications, and testing.
It is tempting to think of filtration performance as being totally determined by the media, but in reality filtration performance is also
Particulate matter (PM) is a pollutant as a mixture of solid particles, liquid droplets and mixture of solid and liquid particles in
Understanding the ability of filter media to collect particles from a gas stream passing through it is key to the successful filter
Particle Size and Distribution in Ambient Air The particle sizes in the ambient air are ranged from 1 nanometer to slightly more
Cigarette smoke is an important aerosol in the air filtration industry and research. It is an unwanted aerosol and therefore there are
Nanofibers are becoming an integral part of many advanced air filtration media thanks to their enormous specific surface area. The large surface
Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and
