British Berkefeld 7" Ultra Sterasyl (ATC) Candle - 2 Pack

The Ultra Sterasyl™ ceramic is filled with granular activated carbon to produce the Super Sterasyl™ filter element. Among other things, activated carbon is very effective at removing chlorine and organics from water. Super Sterasyl™ uses granular activated carbon instead of an activated carbon block in order to give superior flow rates in a gravity filter.

The Ultra Sterasyl will filter out heavy metal within water.
