Capable of removing sediment and other fine particulate throughout its media, this dual stage cartridge also works to reduce odours, remove water pigmentation and other volatile organic compounds

Combining the advantages of both a high dirt loading depth cartridge with the adsorption capabilities of a granular activated carbon, the media used in the construction of the SPECTRUM SCW is a unique combination of powder activated carbon, impregnated into a cellulose fibre that is formed into a sheet and wrapped around a polypropylene core, supported by outer polyethylene netting.

Frequently asked questions

The SCW wraps a carbon-impregnated sheet around a polypropylene core, combining the high dirt-loading capacity of a depth cartridge with the adsorption of activated carbon — a standard carbon block prioritises pure adsorption in a dense, compact form, while the SCW trades a little adsorption density for significantly more sediment capacity.

It captures sediment and fine particulates through its depth media while its activated carbon layer reduces odours, discolouration, VOCs, and chlorine — giving two-stage filtration in a single cartridge.

The SCW suits water that has both sediment and taste/odour issues, since it handles both in one cartridge — if your water is already low in sediment and you just need taste and chlorine reduction, a standard carbon block (SCB) is a more compact, cost-effective choice.

It's available in 9¾" and 20" lengths — the larger 20" format is aimed at reducing maintenance frequency by accommodating a greater dirt load before the cartridge needs replacing.

Yes — combining sediment and carbon (chlorine) reduction in one stage makes the SCW a practical pre-filter ahead of an RO membrane, particularly on supplies with more variable sediment alongside chlorine.
