PURETEC IN-WALL WHOLE-HOME MAINS FILTRATION
Puretec FILTERWALL IM2 Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs the Puretec FILTERWALL IM2 across eligible Brisbane and Gold Coast properties for homeowners wanting high-flow whole-house mains-water filtration in a semi-recessed architectural cabinet.
The FILTERWALL IM2 is installed on the home's incoming cold mains supply so water passes through the filtration system before being distributed to household outlets. Its dual-stage treatment uses a PX05MP2 5-micron sediment cartridge followed by a CB10MP2 10-micron carbon block cartridge.
Puretec publishes a 55 L/min nominal flow rate, 20 mm / ¾" connections, 20" × 4.5" MaxiPlus™ cartridges and a 200–875 kPa operating-pressure range. The system is designed for mains water and must be installed by a licensed plumber.
Quick answer: the Puretec FILTERWALL IM2 is a semi-recessed dual-stage whole-house mains-water filter that combines 5-micron sediment filtration with carbon treatment for chlorine, chemicals, unwanted taste and odour. It delivers a published 55 L/min flow rate, includes a 500 kPa pressure-limiting valve, comes in four COLORBOND®-style finishes and uses the same PX05MP2 + CB10MP2 cartridge pair serviced by Puretec's GR-WH255 Care Kit.

How the Puretec FILTERWALL IM2 Works
The IM2 is installed on the cold mains-water line at the point of entry. Incoming water passes through two large 20-inch cartridges before continuing into the home's plumbing.
1
PX05MP2 Sediment Filtration
The first stage is a 5-micron graded polyspun polypropylene cartridge. Puretec specifies it for reducing dirt, rust, sand, silt, algae and other suspended particles.
The cartridge uses graded-density depth filtration so particulate is captured through the filter media rather than only at its outer surface.
2
CB10MP2 Carbon Filtration
The second stage is a 10-micron bonded activated-carbon block. Puretec specifies this cartridge for reducing chlorine, unwanted taste, odour and sediment.
The bonded carbon design is intended to provide carbon treatment without releasing loose carbon fines during normal operation.
Complete-system flow and individual cartridge flow are different specifications. PX05MP2 is individually rated far above the IM2 system flow and CB10MP2 is individually rated at 60 L/min, while Puretec publishes the complete FILTERWALL IM2 at 55 L/min.
What Does the FILTERWALL IM2 Target?
Sediment & Particles
The PX05MP2 stage provides nominal 5-micron sediment treatment for common suspended material such as dirt, rust, sand, silt and algae.
Chlorine, Taste & Odour
The CB10MP2 carbon block provides Puretec's documented treatment for chlorine and associated unwanted taste and odour.
Documented Chemical Treatment
Puretec describes the exact IM2 as reducing chlorine, chemicals and sediment, with the carbon stage providing the system's chemical, taste and odour treatment function.
Keep treatment claims exact. The current Puretec IM2 documentation does not make the FILTERWALL IM2 a water softener, reverse-osmosis system or UV disinfection system. It should not be described as removing fluoride, dissolved salts, hardness or microbiological hazards unless separate treatment equipment is installed.
Who Is the Puretec FILTERWALL IM2 Best For?
New-Build Homes
Puretec specifically designed the IM2 for new-build applications where the wall framing, plumbing entry and final exterior finish can be planned before completion.
Major Renovations
The semi-recessed format can also suit substantial renovations where wall access and plumbing alterations make an in-wall installation practical.
Design-Focused Mains Filtration
The IM2 suits homeowners wanting whole-house sediment and carbon filtration without leaving two large exposed filter housings on an external wall.

Wall dimensions need to be read with the builder plans. Puretec provides different construction details for wall types and finishes, so the final cut-out, framing, noggins and fixing method should follow the current installation guide rather than being inferred from the external cover dimensions alone.
How Much Wall Space Does the FILTERWALL IM2 Need?
The finished cover is approximately 680 mm wide × 836.3 mm high, with an overall side-view depth of approximately 220.7 mm in Puretec's dimensional drawing.
Because the system is semi-recessed, wall construction matters more than it would for a conventional exposed whole-house filter. Puretec's guide provides builder plans for different brick and rendered-wall configurations, stud spacing, wall openings, framing support and fixing methods.
Do not cut or frame the wall from the external cover measurement alone. Builder plans and the actual wall construction need to be reviewed before the rough-in is completed.
Why the IM2 Works Well for New Builds
Puretec designed the FILTERWALL IM2 so installation can occur in phases during construction.
The enclosure can be incorporated into the building process first, allowing the wall and surrounding finishes to be completed while protecting the filtration assembly and final cover until the appropriate stage of the build.
Plan the Wall Position Early
Locating the IM2 before walls and external finishes are complete gives the plumber and builder more flexibility over framing and pipe routing.
Keep the Exterior Cleaner
The semi-recessed cabinet avoids the visual bulk of conventional exposed 20-inch filter housings and brackets.
Maintain Service Access
The lockable front cover provides future access to cartridges, shut-off valves and the internal bypass arrangement.
FILTERWALL IM2 Installation Requirements
- Installation by a licensed plumber
- Cold mains-water line only
- Suitable position between framing and structural elements
- Wall construction checked against Puretec builder plans
- 20 mm copper or PEX cold-water line as applicable
- Supply pressure between 200 and 875 kPa
- 500 kPa pressure limiting where required
- Suitable inlet and outlet connectors
- Future access to both filter bowls
- Access to shut-off and bypass valves
- Protection from freezing
- Leak management considered where leakage could damage the property
Mains water only. Puretec's current installation guide warns not to use microbiologically unsafe or unknown-quality water without adequate disinfection before the FILTERWALL system.
Built-In Isolation & Bypass
The IM2 filter assembly includes inlet and outlet shut-off valves plus a bypass valve inside the enclosure.
Under normal operation the water is directed through the filter cartridges. During servicing or certain system faults, the internal valve arrangement can isolate the filter assembly and provide a bypass pathway.
Water passing through the bypass is unfiltered. Puretec specifies that the bypass should be used for system failure, repair or where water supply cannot be interrupted rather than as the normal operating mode.

How Much Does Puretec FILTERWALL IM2 Installation Cost?
Use JR's live installation selector above for current supplied-and-installed pricing.
The final scope depends heavily on whether the IM2 is being incorporated into a new build, installed during a renovation or retrofitted into an already completed wall.
Wall access, framing, water-main location, pipe routing, pressure conditions and reinstatement requirements can all affect installation complexity, so this long-form content intentionally does not hard-code a fixed price.
BRISBANE WHOLE-HOME MAINS FILTRATION
Puretec FILTERWALL IM2 Installation Brisbane
JR Gas & Water supplies and installs the Puretec FILTERWALL IM2 across eligible Brisbane properties where mains-water filtration and an integrated semi-recessed finish suit the home.
For Brisbane new builds and renovations, planning the IM2 before wall linings and exterior finishes are completed can simplify the final result because the enclosure, plumbing route and builder framing requirements can be addressed at the correct construction stage.
For existing homes, JR considers whether the incoming water main and wall construction make a semi-recessed retrofit practical or whether another whole-house filtration format is better suited to the property.
GOLD COAST WHOLE-HOME MAINS FILTRATION
Puretec FILTERWALL IM2 Installation Gold Coast
JR Gas & Water also provides FILTERWALL IM2 supply and installation across eligible Gold Coast mains-water properties.
The semi-recessed format can be particularly useful where homeowners want whole-house treatment without a large exposed filter assembly interrupting a finished facade or side passage.
Gold Coast installation planning still needs to account for water-main location, pressure, wall construction, pipe routing and future service access. Where an existing wall cannot practically accommodate the enclosure, an exposed or freestanding Puretec whole-home system may be more suitable.
How Often Does the Puretec FILTERWALL IM2 Need Servicing?
Puretec specifies cartridge replacement every 6–12 months, depending on water quality and household usage.
Puretec also identifies a noticeable decrease in water flow or the return of unwanted taste and odour as indicators that cartridge replacement may be required earlier.
6–12 Month Cartridge Replacement
Both PX05MP2 and CB10MP2 are normally replaced together during scheduled system servicing.
O-Rings
O-rings should be checked for condition and lubrication at cartridge changes. Puretec recommends replacement approximately every 3–5 years.
Post-Service Flush
Puretec instructs that the system be flushed through an open downstream tap for approximately two minutes after cartridge replacement and leak verification.
Puretec GR-WH255 Premium Care Kit
The current genuine service kit for the FILTERWALL IM2 is the Puretec GR-WH255 Premium Care Kit.
Puretec lists this kit for the WH2-55, WH2-60, FILTERWALL IM2 and FILTERWALL IMF2 systems.
PX05MP2
5-micron graded polyspun sediment cartridge for the first treatment stage.
CB10MP2
10-micron bonded carbon block cartridge for chlorine, unwanted taste and odour treatment.
Service Components
The current Care Kit includes genuine replacement cartridges together with replacement O-rings and food-grade lubricant for routine maintenance.
Use genuine cartridge codes when servicing. Puretec identifies PX05MP2 and CB10MP2 as the correct FILTERWALL IM2 replacement pair.
What Happens During a FILTERWALL IM2 Service?
- Isolate the incoming water supply using the system valves.
- Open a downstream tap to relieve pressure.
- Remove the filter bowls carefully.
- Remove the used PX05MP2 and CB10MP2 cartridges.
- Clean and rinse the accessible filter bowls.
- Inspect O-rings for condition and lubrication.
- Fit the genuine replacement cartridge pair in the correct order.
- Reassemble the filter bowls and restore water supply.
- Check accessible joints and housings for leakage.
- Flush the system through a downstream tap before returning it to normal service.
Additional service work may be needed if faults are found. Damaged O-rings, housings, valves, pipework or other installation components are separate from routine cartridge replacement.
FILTERWALL IM2 vs WH2-55 vs FILTERWALL F5
| Feature | FILTERWALL IM2 | WH2-55 | FILTERWALL F5 |
|---|---|---|---|
| Installation Format | Semi-recessed in-wall cabinet | Conventional wall-mounted filter housings | Freestanding FilterWall enclosure |
| Number of Cartridge Stages | 2 | 2 | 3 |
| Cartridges | PX05MP2 + CB10MP2 | PX05MP2 + CB10MP2 | PL20MP2 + PX05MP2 + CB10MP2 |
| Published Flow | 55 L/min | 55 L/min | 55 L/min |
| Connection | ¾" BSP / 20 mm | 1" BSP / 25 mm | ¾" BSP |
| Primary Design Advantage | Architectural semi-recessed installation | Straightforward exposed dual-stage installation | Freestanding 3-stage filtration with extra sediment pre-stage |
| Typical Reason to Compare | New build or renovation with planned wall integration | Simpler retrofit where appearance is less critical | Wanting the larger freestanding FilterWall platform with three cartridges |
The IM2 is primarily differentiated by its in-wall architectural format. Customers wanting the same core PX05MP2 + CB10MP2 cartridge pair without building the filter into a wall can also compare the WH2-55 platform.
Does the FILTERWALL IM2 Remove PFAS?
Puretec's current exact FILTERWALL IM2 product documentation describes the system as reducing sediment, chlorine, chemicals, bad taste and odour.
The exact current IM2 documentation reviewed for this page does not publish an explicit model-level PFAS reduction claim. For that reason, this page does not present PFAS reduction as a verified FILTERWALL IM2 performance claim.
If PFAS treatment is a primary buying requirement, confirm the exact current Puretec system and performance documentation before purchase. Some other current Puretec whole-house models make explicit PFAS claims, but claims should not automatically be transferred between models.
Does the FILTERWALL IM2 Soften Water?
No. The FILTERWALL IM2 is a sediment and carbon filtration system rather than an ion-exchange water softener.
It does not remove hardness minerals through salt regeneration and should not be selected as a substitute for a dedicated softening system where measurable hardness reduction is the objective.
Puretec FILTERWALL IM2 Warranty
Puretec currently provides a 10-year manufacturer warranty for the FILTERWALL IM2, structured as 1 year parts and labour followed by 9 years parts only, subject to its current warranty terms.
Replacement filter cartridges are consumables and are excluded from the 10-year manufacturer warranty.
Correct installation and maintenance are important to warranty coverage. Puretec specifically requires licensed-plumber installation and genuine replacement cartridges in its current documentation.
Puretec manufacturer warranty and JR Lifetime Warranty are separate. JR's live product currently identifies the FILTERWALL IM2 as Lifetime Warranty eligible, with JR eligibility and ongoing coverage subject to JR's own current terms and servicing requirements.
