Stephen’s responsibilities also include training and educating architects and engineers, contractors, technicians and owners about the latest version of ASHRAE Standard 52.2-1999 “Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size”. This standard now uses an alphanumeric system for reporting filter efficiencies. The new standard will use Minimum Efficiency Reporting Value (MERV) parameters. This Standard is ANSI approved and it is written in regulatory or what is referred to as code language. Standard 52.2-1999 is also referenced in both ASHRAE Standards 62.1-2004 and 62.2-2003 “Ventilation for Acceptable Indoor Air Quality”. These Standards are also written in enforceable code language.
