The CADR is basically a reflection of the air flow (CFM) times the efficiency of the air filter. So, if an air filter has 200 cfm and efficiency the CADR would be 200. If the air filter has 200 cfm and 75% efficiency the CADR would be 150. The CADR is a good way to keep from being misled in marketing messages. For example, if a filter has ...

· Since the filter media of the ULPA filter is denser, air flow is 20% to 50% lower than that in the HEPA filters of the same dimensions. As a result, air circulation is lower in rooms or biosafety cabinets with ULPA filters and more power is consumed by the blower to move the air through the filter.

· However, one of the major forces keeping a cleanroom particle free is the air filter system. Cleanrooms employ many different types of filters, including highly efficient particulate air (HEPA) filters and ultralow particulate air filters, but there are two standard air flow patterns that are consistently used: laminar flow and turbulent flow.
