When does a ceramic filter element need replacing?

This depends on the type of ceramic filter being used: Sterasyl™ Should be replaced once cleaning fails to restore the water flow. The level of sediment and contaminants in the water will dictate the filter life. However, the manufacturer recommends that Sterasyl™ filters are replaced after 10,000 litres of water have passed through the filter, to guarantee optimum performance.

Super Sterasyl™, Supercarb™, and Ultracarb™
In combination filter elements (ceramic shells with internal filter media) cleaning the ceramic will not extend the life of the internal material. For example, the ‘life’ of the carbon block in Supercarb™ or Ultracarb™ filter elements is determined by the concentration of chlorine and/or volatile organic compounds in the water supply. This means that the life of the ceramic might or might not exceed the capacity of the carbon insert, depending on the water quality. Whichever point is reached first – the six months usage or the ceramic becoming blocked to the extent where cleaning does not restore the flow – governs when the filter element requires replacing. In most cases, the filter element should be replaced after 6 – 12 months of daily use. The following flow guidelines can be used to guarantee optimum performance:

Super Sterasyl™ 2,000 litres,
Supercarb™ 3,800 litres,
Ultracarb™ 2,300 litres.

After this amount of water has passed through the filter element, the filter will need to be replaced to guarantee optimum performance although the filter capacity can be up to 8000 litres in Australia due to the lower chlorine and chemical levels.
