A pre-filter catches debris before it reaches the main media. Rinsing it takes a few minutes and keeps the flow up between full cleanings, which can then wait months instead of weeks.

A strong value for 20 to 45 gallon tanks: generous media space and low power draw at about the price of the smaller 107.

A small, quiet canister for 10 to 30 gallon tanks. The 207 costs about the same and holds more media, so the 107 makes most sense where cabinet space is tight.
