The Puretec FilterWall F3 is a freestanding three-stage point-of-entry filtration system designed for mains water in small to medium homes.
Water passes through a PL20MP1 20 micron pleated sediment cartridge, a PX05MP1 5 micron polyspun sediment cartridge and a CB10MP1 10 micron carbon block before being distributed to applicable downstream taps, showers and fixtures.
Puretec lists the F3 at a nominal 30 litres per minute and currently identifies sediment, chlorine, chemicals, unwanted taste and odour, and PFAS among the treatment functions of the FilterWall F3 range.
*Puretec's current warranty structure is 1 year parts and labour plus 9 years parts only. Replacement cartridges are excluded and warranty conditions apply.
Puretec currently positions the FilterWall F3 for small to medium houses, with its FilterWall selection guidance identifying the F3 and F4 models for smaller homes and single-bathroom applications.
The FilterWall F3 is installed on the incoming mains-water line so treatment takes place before water is distributed around the property.
The three cartridges progressively treat coarse sediment, finer suspended material and chlorine-related taste and odour concerns.
This differs from an under-sink drinking-water system because the FilterWall is designed to treat the applicable incoming household supply rather than a single drinking outlet.
The first stage uses Puretec's PL20MP1, a 10-inch MaxiPlus pleated sediment cartridge with a nominal 20 micron rating.
This first stage is positioned to intercept larger suspended particles before water reaches the finer second-stage cartridge.
The second stage uses Puretec's PX05MP1, a nominal 5 micron graded-density polyspun sediment cartridge.
The PX05MP1 provides finer particulate treatment after the pleated first stage.
Provides finer nominal filtration than the first-stage PL20MP1.
Uses graded polyspun polypropylene depth filtration.
Reduces suspended dirt, rust, sand and silt before the carbon stage.
The third stage uses Puretec's CB10MP1, a bonded activated-carbon block with a nominal 10 micron rating.
Puretec lists the CB10MP1 for reduction of chlorine, unwanted taste, odour and sediment.
The activated-carbon block is designed to reduce chlorine within its rated operating conditions.
Reduces unwanted taste and odour associated with compatible mains-water supplies.
The CB10MP1 uses a bonded activated-carbon structure rather than loose granular media.
Puretec currently identifies the FilterWall F3 for whole-house reduction of several common mains-water concerns.
The standard FilterWall F3 uses two sediment cartridges and one carbon block. It does not include Puretec's ScaleProtect™ cartridge.
Puretec's comparable FilterWall F4 uses the same 30 L/min 10-inch format but replaces the first-stage configuration with a dedicated ScaleProtect™ stage as part of its scale-control design.
Puretec lists the FilterWall F3 at a nominal 30 litres per minute.
The current operating-pressure specification is 200–875 kPa. Puretec states that an approved pressure limiting device must be installed where line pressure exceeds 500 kPa.
Puretec's current F3 maintenance specification also lists maximum iron at 0.3 mg/L and identifies the F3 as suited to lower-hardness applications, with the F4 provided where ScaleProtect™ treatment is required.
The standard FilterWall F3 includes a bypass arrangement so water can continue to be supplied during system failure, repair or circumstances where the building supply cannot be interrupted.
The bypass is manually operated and should remain closed during normal filtration.

The current FilterWall F Series uses a robust aluminium cover over the filtration assembly.
Puretec describes the enclosure as providing protection for outdoor whole-house filtration installations while also keeping the cartridges, housings and plumbing components contained behind the cover.
Allow additional practical space for plumbing connections, access to the cover and future filter-housing servicing.
Puretec currently lists four standard colour options for the FilterWall F3 range.
Puretec's wider FilterWall range includes additional custom-colour options on selected models. Check the exact F3 ordering code when choosing the cover finish.

Puretec's current FilterWall maintenance guide specifies replacement of the cartridges every 6–12 months, depending on water quality and usage.
Replacement can also be required earlier if there is a noticeable decrease in water flow or if unwanted taste or odour returns.
The first-stage pleated cartridge receives the larger sediment load from the incoming mains supply.
The second stage provides finer sediment filtration and can load faster where incoming particulate levels are elevated.
The carbon cartridge should be replaced within the scheduled interval to maintain its intended treatment function.
The FilterWall F3 uses conventional MaxiPlus housings 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-F3 Premium Care Kit specifically for FilterWall F3 and F3E systems.
The manufacturer-listed cartridge set includes:
Using the genuine kit keeps the replacement sequence aligned with Puretec's current F3 specification.
| Feature | FilterWall F3 | FilterWall F4 |
