Stage 1: (Sediment and Dirt)

2045PS5 Polyspun 5 micron (Disposable)
2045PW5N Pleated 5 micron (Washable)

The first stage of the system is a 5 micron sediment filter which will reduce sediment, rust, algae, sand, silt, fine metal particles etc.

Stage 2: (Taste / odours, Chemicals and Contaminates)

2045CB10 10 micron Carbon Block (Disposable)
2045GAC Granule Carbon (Refillable)

The second stage is a coconut carbon filter that will reduce Chemicals, Chlorine, Organic Compounds, Thrihalomthanes, Fallout from over spray, Bad Taste and Odours greatly improving your water quality.

Stage 3: (Chlorine and Chloramines)

2045CB5 5 micron Carbon Block (Disposable)


2045ORC Catalytic Carbon (Refillable)
2045ORC/Phos Catalytic Carbon and Phosphate (Refillable, with scale inhibitor)

2045ORC Catalytic coconut carbon refillable filter with sediment filter pads at each end. Catalytic carbon has received additional processing to further increase the number of pores on its surface. This improves its chemical adsorption capacity and ability to break apart (catalyse) complex chemicals. Catalytic carbon is particularly useful for removing chloramines from water, as they have a complex structure. The carbon in the third stage filter will need to be replaced at around 6 months but this can vary depending on water quality and usage.

If you are in a hard water area where scale build up is a problem then choose the scale inhibitor system that includes Poly phosphate. This comes with a 2045ORC/Phos 500g cartridge.

Polyphosphate helps reduce scale from bonding to elements and fixtures.
