PURETEC WHOLE-HOME MAINS WATER FILTRATION
Puretec FILTERWALL F3 Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs the Puretec FILTERWALL F3 across eligible Brisbane and Gold Coast properties for homeowners wanting premium whole-house mains-water filtration in a neat weather-protected enclosure.
The FILTERWALL F3 is a 3-stage point-of-entry filtration system designed for small to medium homes on mains water. Puretec currently specifies a 30 L/min nominal flow rate, 10-inch MaxiPlus™ cartridges, ¾" BSP connections and nominal 5-micron system filtration.
Its cartridge configuration combines two sediment stages with carbon treatment, giving the F3 additional particulate protection before the final carbon block while also providing Puretec's documented treatment for chlorine, PFAS, chemicals, unwanted taste and odour.
Quick answer: the Puretec FILTERWALL F3 is a 30 L/min whole-house mains-water filter for small to medium homes. It uses PL20MP1 20-micron pleated sediment filtration, PX05MP1 5-micron polyspun filtration and CB10MP1 10-micron carbon filtration. Puretec currently markets the F3 for chlorine, PFAS and sediment reduction, with a 10-year manufacturer warranty and cartridge servicing every 6–12 months.

How the Puretec FILTERWALL F3 Works
The F3 is installed where mains water enters the home. Water passes through three separate treatment stages before continuing to household taps, showers, baths, laundries and connected appliances.
1
PL20MP1
20-micron washable pleated sediment cartridge. This first stage provides a large filtration surface for coarser suspended sediment and helps reduce loading on the finer downstream stages.
2
PX05MP1
5-micron graded polyspun sediment cartridge. This stage targets finer dirt, rust, sand, silt, algae and suspended particles that pass through the first cartridge.
3
CB10MP1
10-micron bonded carbon block. This final stage provides the F3's carbon treatment for chlorine, unwanted taste, odour and Puretec's documented whole-system PFAS treatment claim.
The F3 uses two sediment stages before carbon. Puretec specifically positions the F3 and F5 configurations where enhanced sediment filtration is desirable.
What Does the FILTERWALL F3 Target?
Sediment
The PL20MP1 and PX05MP1 stages provide progressive sediment filtration to help capture dirt, rust, sand, silt and other suspended particulate before the water reaches the carbon stage.
Chlorine, Taste & Odour
Puretec documents chlorine, chemicals, unwanted taste and odour reduction through the FilterWall filtration platform and final carbon block stage.
PFAS
Puretec currently markets the exact FILTERWALL F3 as helping reduce PFAS across the household mains-water supply.
Keep treatment claims technology-specific. The F3 is not reverse osmosis, UV disinfection or a conventional water softener. It should not be represented as removing fluoride, dissolved salts, hardness or microbiological hazards unless separate treatment equipment is installed.
Who Is the Puretec FILTERWALL F3 Best For?
Small to Medium Homes
Puretec currently positions the 30 L/min F3 for small to medium residential properties where the larger 55 L/min F5 platform is not required.
Mains-Water Properties
The current FilterWall F Series maintenance guidance specifies mains-water use on the home's cold-water supply.
Homes Wanting Extra Sediment Protection
The F3 uses two separate sediment stages before its carbon cartridge, unlike the F4 configuration which uses a ScaleProtect™ stage instead.
Is the FILTERWALL F3 Right for Your Home?
Good Choice
- Home is supplied by treated mains water
- Whole-house filtration is required
- 30 L/min nominal flow suits household demand

Where Should the FILTERWALL F3 Be Installed?
The F3 is installed on the cold mains-water line at the point where water enters the property, before the supply branches to the home's internal outlets.
The location should allow suitable plumbing access while preserving enough room to remove the external cover and service all three 10-inch filter bowls.
External Wall
A suitable outside wall can provide a clean installation where the water main is exposed and accessible.
Freestanding Position
The FilterWall format can also suit a properly supported freestanding installation where the pipework and selected JR package allow it.
Service Access
The installation should leave enough room to operate isolation valves, remove filter bowls and complete future cartridge servicing.
FILTERWALL F3 Installation Requirements
- Licensed plumber installation
- Mains-water cold line identified
- Suitable point-of-entry location
- 200–875 kPa operating pressure
- Pressure limiting where line pressure exceeds 500 kPa
- Suitable isolation arrangement
- Appropriate pipework routing
- Stable wall or freestanding support
- Access to the bypass arrangement
- Room for cartridge servicing
- Protection from freezing conditions
- Commissioning and leak checks
Mains water only. Puretec warns not to use microbiologically unsafe or unknown-quality water without adequate disinfection before the FilterWall system.
Built-In Bypass & Isolation
The standard FILTERWALL F3 includes a bypass arrangement together with inlet and outlet isolation controls.
This allows the filtration assembly to be isolated during servicing or certain fault conditions while providing a temporary pathway for incoming water where the property supply cannot be interrupted.
Bypass water is unfiltered. Puretec specifies the bypass for servicing, system failure or situations where supply cannot be disrupted rather than as the normal operating configuration.

How Much Does Puretec FILTERWALL F3 Installation Cost?
Use JR's live package selector above for current supplied-and-installed pricing.
The final installation scope changes depending on whether the incoming main is already exposed, whether the system is wall mounted or freestanding, existing water pressure and the amount of pipework required.
Because those variables can change, this page deliberately leaves the live JR product configuration as the pricing source rather than hard-coding a fixed historical installation figure.
BRISBANE WHOLE-HOME WATER FILTRATION
Puretec FILTERWALL F3 Installation Brisbane
JR Gas & Water supplies and installs the FILTERWALL F3 across eligible Brisbane mains-water properties where the 30 L/min platform suits household demand.
For Brisbane installations, JR considers the position of the incoming water main, available pressure, external access and whether the preferred location allows the FilterWall cover and cartridges to remain serviceable.
The F3 can be a practical whole-home option for small to medium properties wanting chlorine, PFAS and sediment treatment without moving to the physically larger 20-inch F5 platform.
GOLD COAST WHOLE-HOME WATER FILTRATION
Puretec FILTERWALL F3 Installation Gold Coast
JR Gas & Water also installs the Puretec FILTERWALL F3 across eligible Gold Coast mains-water properties.
Gold Coast homes vary considerably in side access, water-main position and available exterior space, so the best F3 installation position is chosen around both the plumbing layout and future service access.
Where household demand is higher or the property has multiple bathrooms operating simultaneously, JR can also assess whether the larger 55 L/min F5 platform is more appropriate.
How Often Does the Puretec FILTERWALL F3 Need Servicing?
Puretec specifies cartridge replacement every 6–12 months, depending on water quality and household usage.
Filters may need replacement earlier if household flow decreases or unwanted taste and odour begin to return.
6–12 Month Cartridge Cycle
All three F3 cartridges are normally renewed together during scheduled servicing.
O-Ring Maintenance
Puretec recommends inspecting and lubricating the bowl O-rings during cartridge changes and replacing them approximately every 3–5 years.
Post-Service Flush
After leak checks, Puretec instructs that water be flushed through a downstream tap for approximately two minutes before normal use.
Puretec FR-F3 Premium Care Kit
Puretec specifies the FR-F3 Premium Care Kit for FILTERWALL F3 and F3E servicing.
PL20MP1
20-micron washable pleated sediment cartridge for the first stage.
PX05MP1
5-micron graded polyspun sediment cartridge for finer particulate treatment.
CB10MP1
10-micron carbon block cartridge for chlorine, unwanted taste and odour treatment.
The genuine FR-F3 kit also includes routine service components. Puretec currently supplies the kit with genuine cartridges, replacement O-rings and food-grade lubricant.
What Happens During a FILTERWALL F3 Service?
- Isolate the FilterWall water supply.
- Open a downstream tap to relieve pressure.
- Remove the three filter bowls carefully.
- Remove the used PL20MP1, PX05MP1 and CB10MP1 cartridges.
- Clean the accessible filter bowls.
- Inspect the bowl O-rings and lubrication.
- Fit the genuine replacement cartridges in the correct stage order.
- Reassemble the filter bowls.
- Restore water and check for leakage.
- Flush through a downstream tap before returning the system to service.
Routine cartridge service does not automatically include repairs. Damaged housings, valves, O-rings, pipework or other installation faults can require additional parts or plumbing work.
FILTERWALL F3 vs F4 vs F5
| Feature | FILTERWALL F3 | FILTERWALL F4 | FILTERWALL F5 |
|---|---|---|---|
| Puretec Home Size Positioning | Small to medium | Small to medium | Medium to large |
| Published Flow | 30 L/min | 30 L/min | 55 L/min |
| Cartridge Size | 10" × 4.5" | 10" × 4.5" | 20" × 4.5" |
| Stage 1 | PL20MP1 sediment | PX05MP1 sediment | PL20MP2 sediment |
| Stage 2 | PX05MP1 sediment | CB10MP1 carbon | PX05MP2 sediment |
| Stage 3 | CB10MP1 carbon | ScaleProtect™ | CB10MP2 carbon |
| Primary Difference | Extra sediment stage | Scale-management stage | Higher-flow F3-style treatment platform |
| Typical Reason to Compare | Small/medium home wanting sediment + carbon treatment | Small/medium home where scale management is important | Larger household requiring greater flow |
The larger or more complex model is not automatically the better choice. Select between F3, F4 and F5 based on household flow demand and the actual treatment priority.
Does the FILTERWALL F3 Soften Water?
No. The FILTERWALL F3 is a sediment and carbon filtration system rather than a conventional ion-exchange water softener.
Puretec directs customers concerned about scale toward the F4 or F6 configurations containing ScaleProtect™. Where true hardness removal is required, a dedicated water-softening system should be considered separately.
Puretec FILTERWALL F3 Warranty
Puretec currently specifies a 10-year manufacturer warranty for the FILTERWALL F3, structured as 1 year parts and labour followed by 9 years parts only, subject to current warranty conditions.
Replacement cartridges are consumables and are excluded from the 10-year system warranty.
Puretec also requires genuine replacement cartridges to maintain the intended system performance and warranty pathway.
JR Lifetime Warranty is separate from Puretec's manufacturer warranty. Any JR Lifetime Warranty eligibility shown on the live product page is subject to JR's current eligibility, workmanship and servicing terms.
