Big Blue 3-Stage Replacement Cartridge Set

The sediment filter is usually the first stage in a water filtration system. It serves to remove visible dirt particles such as mud, rust and sand from the water. A melt-blown filter cartridge has a multi-layer structure and is self-bonded, thus not making use of a chemical binder.

Sediment filters are rated by a micron number or aperture size which referes to the largest dirt particle that will pass through the filter. A micron is a 0.001 millimeters. The most common sediment filters available are 1, 5, 10, 20 and 50(micron).

The carbon block has a 5micron aperture and serves to remove chlorine and its byproducts from water as well as any organic tastes and odours. Note that Hydrogen Suphide with a rotten egg smell often associated with ground water is not removed by a carbon block.

Dimensions:
-Length: 500mm
-Outside diameter: 110mm
-Inside diameter: 26mm

Recommendations:
-Use successively finer aperture filters in series for distributing the dirt load and achieving the best result
-Replace the sediment filter when it is visually dirty or water flow or pressure is reduced
-Replace the carbon block when you start to taste or smell chlorine or other unwanted tastes and odors
-Consider using a backwashable media filter as a more sustainable alternaitve to single use plastic cartridges
