Activated charcoal is used in filters in compressed air to remove oil vapours, odour, and other hydrocarbons from the air. The most common designs use a 1 stage or 2 stage filtration principle in which activated carbon is embedded inside the filter media. The solids are trapped in the charcoal particles, while the filtered air passes through.
NOTE: Activated carbon should be the final chemical in the filtration train and must always be preceded by molecular sieve

In a typical machine used by most dive operations the filter should be changed at the following intervals
20 deg C every 40 hours
30 deg C every 23 hours
40 deg C every 14 hours
