particles of concern. High-efficiency particulate air (HEPA) filters are even more efficient at filtering human-generated infectious aerosols. By definition, a HEPA filter must be at least 99.97% efficient at capturing particles 0.3 µm in size. This 0.3 µm particle approximates the most penetrating particle size (MPPS) through the filter.

the air cleaner can filter and the larger the area it can serve. Most air cleaner packaging will tell you the largest size area or room it should be used in. Portable air cleaners often achieve a high CADR by using a high-efficiency particulate air (HEPA) filter. To filter gases, choose a portable air cleaner with an activated carbon filter or ...

Side Stream Filtration for Cooling Towers - Energy

This results in both water and energy efficiency gains due to a reduction in the amount of water discharged from the cooling system and a decrease of scale formation on the heat transfer surfaces. The filter types examined in the technology evaluation are centrifugal separators, automatic screen filters, plastic disc filters, and sand filters.
