The Puretec FilterWall IM2 is a semi-recessed, in-wall whole-house filtration system designed for mains water. It combines two large-format filter cartridges with a lockable exterior cover so the filtration system can be incorporated into the wall rather than taking up additional pathway or external wall space.
The current FilterWall IM2 uses a Puretec PX05MP2 5 micron sediment cartridge followed by a Puretec CB10MP2 10 micron carbon block cartridge. Puretec lists the system for reduction of sediment, chlorine, chemicals, unwanted taste and odour, with its current whole-house range information also listing PFAS reduction for the FilterWall IM2.
Puretec lists a nominal system flow rate of 55 litres per minute, operating pressure of 200–875 kPa, 20 mm / ¾" BSP connections and 20-inch MaxiPlus cartridges.
*Puretec's current warranty is 1 year parts and labour plus 9 years parts only. Replacement cartridges are excluded and warranty conditions apply.
Puretec developed the FilterWall IM2 as a semi-recessed whole-house filtration system for installations where the filter needs to integrate more closely with the exterior of the property.
The enclosure is installed within the wall structure, while the removable front cover remains accessible for servicing.
Puretec specifically positions the FilterWall IM2 for new-home construction where the enclosure can be incorporated during the building process.
The outer enclosure can be installed during construction, with the filtration assembly fitted later when the remaining plumbing fixtures are commissioned.
The front cover uses lockable latches and can be removed when cartridge servicing or system access is required.
The FilterWall IM2 is installed on the incoming cold-water mains line before the treated supply is distributed through the property.
Water first passes through the PX05MP2 sediment cartridge and then the CB10MP2 carbon block before continuing to applicable downstream taps, showers and fixtures.
This provides central filtration rather than treating only one drinking-water outlet.
The first stage uses Puretec's PX05MP2, a 5 micron, 4.5" × 20" MaxiPlus sediment cartridge manufactured from virgin polypropylene.
Puretec uses graded-density polyspun construction to provide depth filtration through the cartridge.
The PX05MP2 has a nominal 5 micron filtration rating.
Designed to reduce suspended dirt and particulate rust from the incoming supply.
Provides depth filtration for sand, silt and similar suspended material.
Puretec also lists suspended algae among the material reduced by the PX Series.
The density changes through the polypropylene media to capture particulate matter through the cartridge depth.
Puretec lists the individual PX05MP2 cartridge at up to 156 L/min. The complete FilterWall IM2 remains rated at 55 L/min.
The second stage uses Puretec's CB10MP2, a bonded activated-carbon block cartridge measuring 4.5" × 20".
Puretec lists the CB10MP2 for reduction of chlorine, unwanted taste, odour and sediment.
The CB10MP2 has a nominal 10 micron filtration rating.
The activated-carbon block provides chlorine reduction within its rated operating conditions.
Designed to reduce unwanted taste and odour associated with compatible mains-water supplies.
The cartridge uses bonded activated carbon rather than loose granular carbon media.
Puretec incorporates SilverPlus technology to inhibit bacterial growth within the filter media.
Puretec lists the individual CB10MP2 at 60 L/min. Complete-system flow remains 55 L/min.
Puretec's current product and whole-house range information identifies the FilterWall IM2 for reduction of:
The FilterWall IM2 contains sediment and carbon filtration only. It does not contain Puretec's ScaleProtect™ cartridge or an ion-exchange water-softening stage.
If hardness or scale treatment is required, select a system specifically designed for that purpose rather than assuming it is included with the IM2.
Puretec lists the FilterWall IM2 with a nominal flow rate of 55 litres per minute.
The manufacturer lists an operating pressure range of 200–875 kPa and supplies a 500 kPa pressure limiting valve as part of the FilterWall assembly.
The current FilterWall IM2 uses 20 mm / ¾" BSP water connections.
Puretec's installation guidance specifies connection to the cold-water line using suitable 20 mm copper, PEX or other approved plumbing materials.
Inlet and outlet connection fittings to the home's pipework need to suit the installation and are not automatically supplied as part of every wall-plumbing arrangement.
The FilterWall filtration assembly incorporates valve components that allow the installed system to be isolated and serviced from within the cabinet.
The FilterWall IM2 is available with four exterior cover finishes using registered Australian building-colour names.
The colour names are registered trademarks of BlueScope Steel Limited. This does not mean every structural component of the FilterWall should be described as manufactured from BlueScope Steel.
Puretec describes the lockable FilterWall cover as providing protection for the filtration system from harsh Australian weather while maintaining a finished exterior appearance.
The installation guide still specifies that the enclosure and system should be protected from unsuitable harsh environments, including excessive heat, direct sunlight, saltwater spray, direct water exposure and freezing conditions.
The installation position should therefore follow Puretec's current builder and plumbing requirements rather than assuming the cabinet can be fitted in any exposed location.

Puretec's installation documentation identifies the main supplied components as including:
The FilterWall IM2 is particularly suited to new builds because Puretec allows the outer enclosure to be installed during construction and the filter assembly to be installed later.
This allows the filtration hardware and cover to remain protected while other building and plumbing work continues.
Puretec's current FilterWall user guide specifies replacement of the filter cartridges every 6–12 months, depending on water quality and usage.
Puretec also identifies the return of unwanted taste or odour and a decrease in water flow as indicators that the cartridges may require replacement.
The first-stage sediment cartridge can load more quickly where the incoming mains supply carries higher particulate levels.
The carbon block should be replaced within the applicable service interval rather than being left in service indefinitely.
Puretec recommends replacement of the filter-housing O-rings approximately every 3–5 years to help maintain a watertight seal.
The FilterWall IM2 does not use an automatic cartridge shut-off or quick-twist cartridge system. Puretec's service procedure requires the water supply to be isolated and pressure relieved before the bowls are opened.
Puretec currently lists the GR-WH255 Premium Care Kit for the FilterWall IM2, FilterWall IMF2, WH2-55 and WH2-60 systems.
The manufacturer describes the kit as containing genuine Puretec replacement cartridges together with replacement O-rings and food-grade lubricant for routine servicing.
