Measuring a filter's flow in terms of gallons per hour gives a rough understanding of how much filtration it's capable of. However, a simple thought experiment shows that it has its deficiences.
Imagine two nearly identical filters. One uses only a single thickness of cheesecloth as its media. The other uses a foam block, activated carbon, and a Bio-Wheel.
Both will move approximately the same amount of water, but the latter filter will do more filtration work.
Are there other measures of filtration effectiveness that better than gallons per hour?
