Olf (unit)

The '''olf ''' is a unit used to measure the strength of a pollution source. It was introduced by Danish professor P. Ole Fanger; the name "olf" is derived from the Latin word olfactus, meaning "smelled".

One olf is the sensory pollution strength from a standard person defined as an average adult working in an office or similar non-industrial workplace, sedentary and in thermal comfort, with a hygienic standard equivalent of 0.7 baths per day and whose skin has a total area of 1.8 square metres. It was defined to quantify the strength of pollution sources which can be perceived by humans.

The perceived air quality is measured in decipol.
