By example, your bathroom is 8'W x 10.5L which is 84sq.ft You would then multiply that by the ceiling height to get cubic feet in the room. For the purpose of this example I will assume an 8' ceiling, thus we get 84sq.ft x 8' height equals 672cubic feet. The total volume of the room in 672cu.ft and we want 4 air exchanges per hour so we would need to move 672cu.ft x 4 = 2688cu.ft per hour.
