The new EF filter range includes many design improvements compared to the original series.

The improvements include; an easier, more consistent priming functionality and a stronger, more durable body design.
For marine fish keepers, we have paid special attention to improving existing fittings so they last longer in a salt water environment. The UV models are now powered by a magnetic connection.
In addition to these changes, we now supply each filter with a full 2 years warranty for that extra peace of mind.
