The Puretec FilterWall F4E is a freestanding three-stage whole-house mains-water filtration system designed to reduce sediment, chlorine, unwanted taste and odour while also incorporating Puretec's ScaleProtect™ technology for scale-control applications.
The current FILTERWALL-F4E-LF uses a PX05MP1 5 micron polyspun sediment cartridge, a CB10MP1 10 micron carbon block and a SCALEPROTECT-MP1 scale-prevention cartridge.
Puretec lists a nominal system flow rate of 30 litres per minute, ¾" BSP Female inlet and outlet connections and a current Midnight Black aluminium cover. The F4E is the bypass-excluded version of the FilterWall F4.
Puretec identifies the FilterWall F4E as best suited to scale, chlorine and sediment reduction.
The current installation guide lists a suitable hardness range of approximately 80–140 mg/L for this ScaleProtect™ configuration.
The F4E treats incoming mains water through three separate 10-inch MaxiPlus cartridges.
The first stage addresses suspended sediment, the second provides carbon treatment for chlorine, taste and odour, and the third uses ScaleProtect™ media to minimise mineral scale accumulation.
No electrical power, salt tank or regeneration cycle is required for these filtration stages.
The first stage uses Puretec's PX05MP1, a nominal 5 micron MaxiPlus sediment cartridge manufactured from graded polypropylene media.
Provides nominal 5 micron particulate filtration.
Uses Puretec's 10-inch MaxiPlus cartridge format.
Reduces suspended dirt, rust, sand, silt and other particulate material before the carbon stage.
The second stage uses the Puretec CB10MP1, a bonded activated-carbon block cartridge with a nominal 10 micron rating.
Puretec lists the CB10MP1 for reduction of chlorine, unwanted taste, odour and sediment.
Provides activated-carbon treatment for chlorine within the cartridge's rated conditions.
Reduces unwanted taste and odour associated with compatible mains-water supplies.
Puretec lists the individual CB10MP1 at up to 30 L/min, matching the F4E's nominal system-flow rating.
The third stage uses Puretec's SCALEPROTECT-MP1, a 4.5" × 10" cartridge designed to minimise scale accumulation in pipes, appliances and on glass surfaces.
Puretec describes ScaleProtect™ as retaining calcium and magnesium rather than removing them through conventional ion exchange.
The F4E should not be described as a conventional water softener. ScaleProtect™ is designed to reduce the impact of scale while retaining calcium and magnesium.
Puretec currently identifies the FilterWall F4E for reduction of:
Puretec lists the FilterWall F4E at a nominal flow rate of 30 litres per minute.
The current F4E is therefore part of Puretec's 10-inch FilterWall range rather than the larger 55 L/min 20-inch range.
Puretec also lists maximum iron at 0.3 mg/L and a suitable hardness level of 80–140 mg/L for the F4E configuration.
The F4E uses the same cartridge sequence as the standard F4, but Puretec supplies the F4E without the bypass assembly.
Puretec's current maintenance documentation also notes that the pressure limiting valve and bypass assembly supplied with applicable standard FilterWall models are not included with the F3E and F4E.
Standard FilterWall F4 configuration with the Puretec bypass assembly included.
Same three cartridges and 30 L/min filtration platform, but bypass connections are excluded for installer configuration flexibility.
The F4E is a freestanding FilterWall system, not a semi-recessed in-wall model.
Puretec uses a robust aluminium exterior cover around the filtration assembly and lists the F4E in Midnight Black.
Puretec currently lists the standard FILTERWALL-F4E-LF with a Midnight Black aluminium cover.
Customers wanting other standard FilterWall colours should compare the regular F4 range, which is offered in additional finishes and includes the bypass configuration.
Allow additional space for plumbing connections, service access, cover removal and future filter-bowl servicing.

The FilterWall F4E is installed on the cold mains-water line at the property's point of entry.
Puretec's current guide specifies installation by a licensed plumber.
Puretec's FilterWall F Series guide allows the enclosure to be installed on a suitable flat surface, using supplied posts in an appropriate ground installation or mounted where the structure and installation method are suitable.
The chosen location should provide drainage, service access and protection from excessive heat, direct sunlight, saltwater spray, direct water exposure and freezing conditions.
Puretec specifies replacement of the FilterWall cartridges every 6–12 months, depending on water quality and usage.
A decrease in water flow or the return of unwanted taste or odour can indicate that servicing is required earlier.
The first-stage sediment cartridge collects particulate material from the incoming mains supply.
The carbon stage should be renewed within the applicable interval to maintain its intended treatment function.
The scale-prevention stage is replaced as part of the complete F4/F4E maintenance set rather than being treated as a permanent cartridge.
The F4E uses conventional filter bowls rather than quick-twist cartridges.
Puretec recommends replacing the housing O-rings approximately every 3–5 years to help maintain a watertight seal.
Puretec lists the FR-F4 Premium Care Kit for FilterWall F4 and F4E systems.
The manufacturer-listed kit contains the genuine replacement cartridges required for the three treatment stages and includes servicing components such as O-rings and food-grade lubricant.
