# What CFM means?

cubic feet per minute

CFM is an abbreviation for cubic feet per minute (cu ft/min). When used in the context of a particle counter’s flow rate, it is a measurement of the velocity at which air flows into the sample probe. For example, a flow rate of 0.1 CFM means the particle counter will sample 0.1 cubic feet of air per minute.
