Talk:Philip Greenspun illustration project/Round 1/Request list/48

The given example http://www.cdc.gov/OD/OHS/biosfty/bsc/fig5a.htm does not show a HEPA filter. This is a Biohazard contaiment cabinet that utilizes HEPA filters. An illustration of a filter would be http://www.cdc.gov/OD/OHS/biosfty/bsc/fig1.htm

Also, I would like to point out that the definition of a HEPA filter is abstract, i. e. any picture of a filter would show a more or less arbitrary example. The Department of Energy definition does not give more than requirements for filter efficiency, external dimensions, mechanical properties and some general rules for materials. --Hk kng 23:45, 29 July 2008 (UTC)
