Three UV Systems to Start With
Choose How You Want to Order
Not every water filter setup is the same. Choose supply only if you already have an installer arranged, select supply and installation together where available, or compare your options if you are still deciding what best suits your home.
Supply Only
Best if you already have a licensed plumber or installer arranged.
You receive the water filter system and the components listed with that product. Installation and site-specific plumbing work are not included unless shown or selected separately.
Additional cartridges, fittings, valves, pipework changes, pressure limiting valves, electrical work, drainage, compliance upgrades or removal of existing equipment may be required depending on your installation.
Supplied & Installed
Best if you want the water filter system and installation organised together.
Select your preferred water filtration system, complete the installation questions on the product page and choose any applicable installation options before checkout.
Installation availability and final requirements depend on your location, access, existing plumbing, selected filter system and site conditions.
Not Sure What You Need?
Water filter systems vary by filtration type, flow rate, cartridge setup, property size and water quality concerns.
Compare under-sink, whole-house and drinking-water filtration systems using the ranges and selection tools throughout the site.
Consider your water source, treatment goals, required flow, cartridge setup, property size and installation location before choosing.
UV Water Filter Systems for Whole Home, Rainwater & Tank Water
UV water filter systems use ultraviolet light as a microbiological treatment stage for water passing through the UV chamber.
They are commonly used with rainwater tanks, rural water supplies, private water systems, whole-home filtration and other applications where microbiological treatment is required.
Installed Today supplies UV whole-home filtration systems across supported mainland Australian markets, with supplied and installed options available on selected systems in eligible Brisbane and Gold Coast service areas.
UV Whole Home Water Filter Systems
How Does UV Water Treatment Work?
Water passes through a chamber containing a UV lamp.
The ultraviolet energy is used to inactivate susceptible microorganisms by disrupting their ability to reproduce.
UV treatment does not add disinfecting chemicals to the water and does not work by physically trapping microorganisms in the UV chamber.
What Does a UV Water Filter Treat?
Properly selected and maintained UV systems are used to address microbiological risks from susceptible organisms in water.
Product-specific UV performance depends on UV dose, flow rate, water quality, lamp output, chamber design and maintenance.
Where microbiological safety matters, the entire water treatment system and source should be considered rather than relying on one component in isolation.
UV Is Not a Sediment, Carbon or Reverse Osmosis Filter
Sediment
UV light does not physically remove dirt, rust, sand, silt or other particles.
Chlorine & Odour
Carbon filtration is typically used where chlorine taste and odour reduction is required.
Dissolved Substances
UV does not automatically remove salts, hardness, metals or other dissolved contaminants.
PFAS & Chemicals
Specific chemical reduction requires suitable verified filtration media or membrane treatment.
Water Softening
UV does not soften water or remove hardness in the way a suitable water softener does.
RO Treatment
Reverse osmosis uses a membrane and performs a different treatment function from UV.
Why UV Water Systems Need Clear Water
UV treatment works best when the light can pass effectively through the water.
Sediment, cloudiness, suspended solids and other material can reduce UV transmission or shield microorganisms from the light.
This is why whole-home UV systems are commonly installed after suitable sediment filtration and, where appropriate, other filtration stages.
Sediment Filtration Protects the UV Treatment Stage
A sediment cartridge helps reduce particles before water reaches the UV chamber.
The required micron rating and cartridge configuration depend on water quality, expected flow, system design and manufacturer requirements.
Choosing the finest possible cartridge is not automatically better because excessive restriction can reduce household flow and increase pressure drop.
Why Many Whole Home UV Systems Also Include Carbon
Carbon and UV perform different jobs.
Carbon filtration may be used for product-specific reduction of chlorine, taste, odour and selected organic compounds, while UV provides the microbiological treatment stage.
Combining sediment, carbon and UV can therefore address several different water-quality goals within one system.
UV Water Filters for Rainwater Tanks
Rainwater is one of the strongest applications for whole-home UV treatment.
A rainwater setup can be exposed to roof debris, bird or animal contamination, tank sediment and other microbiological risks.
A typical treatment strategy may include suitable tank management, sediment filtration and UV, with additional filtration selected around the actual water-quality goals.
Water testing can help identify issues that UV alone will not address.
UV for Whole Home Tank Water Supply
Homes supplied primarily from a water tank need the UV system sized for household flow rather than simply the tank volume.
Pump performance, number of bathrooms, simultaneous outlet use, pipework and the UV system's rated treatment flow all influence the correct setup.
The pump should not push water through the UV chamber faster than the treatment system is designed to handle at the required UV dose.
UV for Bore, Rural & Private Water Supplies
UV can form one part of a treatment system for private water sources, but the source should be properly understood first.
Bore or private water can contain hardness, iron, manganese, sediment, colour, salinity, pH issues or other characteristics that UV does not correct.
Water testing is especially useful where the supply has not already been treated by a municipal water provider.
Do You Need UV on Treated Mains Water?
Town water and private rainwater have different risk profiles.
Municipal mains water is already treated before entering the property, so the reason for adding residential UV should be clearly identified rather than treating it as a mandatory stage for every home.
Where the primary concern is sediment, chlorine taste or general household filtration, a standard whole-home sediment and carbon system may be the more direct treatment approach.
UV Systems Must Be Sized for Peak Water Flow
Flow rate is one of the most important UV sizing criteria.
Water needs sufficient exposure to the UV energy while passing through the chamber.
If household flow exceeds the system's relevant rated flow, exposure can fall below the intended treatment conditions.
Size the UV system around realistic simultaneous use rather than average daily water consumption.
Understand UV Dose When Comparing Systems
UV flow ratings can be published at different UV doses.
A higher published flow figure can therefore correspond to a different treatment dose than a lower flow figure from the same UV chamber.
Compare flow rates at equivalent UV doses rather than simply choosing whichever system advertises the highest litres per minute.
Puretec G6, G7, G12 & G13 UV Whole Home Systems
The current Installed Today UV range includes Puretec G6, G7, G12 and G13 whole-home systems.
These combine cartridge pre-filtration with UV treatment and provide several system configurations for different whole-home treatment goals.
Compare the exact cartridge stages, rated UV flow, connection size, dimensions and service requirements between individual models.
WFW Twin & Triple UV Whole Home Water Filters
Water Filter World currently provides four UV options in the collection: Twin 20″ Big Blue, Twin 20″ Enclosed, Triple AntiScale Big Blue and Triple AntiScale Enclosed.
These systems combine large-format whole-home cartridge filtration with a separate UV treatment stage.
Choose between exposed Big Blue and enclosed configurations based on treatment needs, available space, service access and preferred installation finish.
Puretec Hybrid P1, P3, P9 & P12 UV Systems
Puretec Hybrid systems provide a more integrated rainwater-treatment package with filtration and UV inside a weather-protected enclosure.
Current Installed Today options include the Hybrid P1, P3, P9 and P12.
Depending on the exact model, Hybrid configurations can also integrate pump and rainwater-management equipment.
Puretec Hybrid P1 UV Treatment Capacity
Puretec's current Hybrid P1 specification publishes different flow rates depending on UV dose.
For example, manufacturer data lists approximately 70L/min at 30mJ/cm², while higher nominal flow figures are available at lower UV doses.
This is a useful example of why UV flow ratings need to be compared together with the dose at which the rating is achieved.
Exposed Big Blue or Enclosed UV System?
Big Blue System
Large-format exposed housings provide straightforward access to cartridges and can suit plant areas, garages and protected service locations.
Enclosed System
Cabinet-style systems provide a neater finished appearance and can protect components from physical exposure.
Service Access Still Matters
Enclosures still need adequate clearance for cartridge, lamp and quartz-sleeve replacement.
UV Lamps Are a Service Item
UV lamp output changes with operating time even if the lamp still appears to be illuminated.
Lamps therefore need replacement according to the manufacturer's service interval rather than waiting for visible failure.
Use the exact lamp specified for the UV system being serviced.
Why the Quartz Sleeve Needs Cleaning
The UV lamp is normally separated from the water by a quartz sleeve.
Scale, mineral deposits or fouling on the sleeve can reduce the amount of UV energy reaching the water.
Inspection and cleaning of the sleeve are therefore an important part of UV maintenance.
UV Systems Also Need Cartridge Servicing
Whole-home UV packages usually rely on cartridge pre-filtration.
Those cartridges have separate service intervals from the UV lamp and quartz sleeve.
Replacement frequency depends on water quality, water use, cartridge capacity and the exact filtration setup.
UV Water Filters Need Electricity
The UV lamp and controller require a suitable electrical supply.
The installation position therefore needs access to appropriate power in addition to the plumbing connections.
Electrical work is separate from plumbing work unless specifically included in the selected installation package.
UV Treatment Stops When the Lamp Has No Power
A UV system needs the lamp operating to provide the intended UV treatment stage.
During a power outage, water may still physically pass through the plumbing system depending on the installation, but active UV treatment will not be occurring.
Properties relying on untreated private water should consider how loss of power affects the overall treatment strategy.
Match the UV System to the Water Pump
Rainwater and private-water systems are often supplied by a pressure pump.
The pump, filters and UV system need to work together as one hydraulic system.
A powerful pump does not justify installing a UV chamber with insufficient rated treatment flow.
Pressure drop through filters should also be considered when sizing the pump and pipework.
Test Private Water When the Source Is Uncertain
Water testing can help identify problems a UV system will not address.
Depending on the source, relevant issues can include microbiology, sediment, hardness, iron, manganese, pH, salinity, colour and other water-quality characteristics.
Treatment should then be designed around the actual water rather than simply adding more filter stages.
Replacing an Existing UV Water Filter System
Existing UV equipment provides a useful starting point when selecting a replacement, especially if the previous system supplied enough flow.
- Existing system model
- Rated UV flow
- UV dose
- Lamp type
- Quartz sleeve
- Filter stages
- Cartridge size
- Pipe connection size
- Power supply
- Household peak flow
- Pump performance
- Service clearance
Size UV Around Simultaneous Household Demand
Whole-home UV systems need enough rated treatment flow for the peak demand that can occur when several outlets operate together.
Bathroom count, shower flow, taps, appliances and pump performance can all contribute to simultaneous flow.
Household occupant count is useful context but should not replace actual hydraulic sizing.
Allow Space for UV Servicing
UV systems need enough space not only for installation but also for future servicing.
The lamp and quartz sleeve may need to be withdrawn from the chamber, while filter housings need clearance for cartridge changes.
Garages, pump sheds, plant areas and protected service locations can work well where the manufacturer's environmental requirements are met.
Protect UV Equipment from Unsuitable Exposure
UV controllers, electrical connections, filter housings and other components need to be installed in conditions permitted by the specific manufacturer.
Do not assume every UV package can be left fully exposed outdoors simply because part of the plumbing equipment is weather resistant.
Enclosed products can provide additional protection, but their exact installation requirements still apply.

Treat UV as One Part of the Water Treatment System
UV is strongest when the water reaching the chamber is already suitable for UV treatment.
Start with the water source and treatment goal, then compare water clarity, pre-filtration, peak flow, UV dose, lamp type, quartz sleeve, electrical supply, pump performance and servicing access.
The best UV system is not automatically the model with the most stages or highest advertised flow. It is the system correctly sized and maintained for the actual water source and household demand.
Ultraviolet UV Water Filtration System FAQs
Common questions about choosing, ordering and installing ultraviolet UV water filtration systems for whole-home water treatment, rainwater, tank water, mains water, bacteria reduction, pre-filtration and ongoing UV system maintenance.
What is an ultraviolet UV water filtration system?
An ultraviolet UV water filtration system uses UV light to help treat water as it passes through the UV chamber. It is commonly used as part of a whole-home water filtration setup to help reduce microbiological risks such as bacteria and viruses, depending on the water source, flow rate, system size and maintenance.
Does UV filtration remove dirt, sediment or chlorine?
UV light does not physically remove dirt, sediment, rust, chlorine, taste or odour by itself. That is why UV systems are usually paired with pre-filters such as sediment and carbon cartridges. The pre-filters help improve water clarity and support better UV performance.
Why does a UV water filter need pre-filtration?
UV works best when the water is clear. Sediment, dirt and discolouration can reduce UV effectiveness by shielding microorganisms from the UV light. A suitable pre-filter helps reduce particles before the water reaches the UV chamber and can also help protect the UV sleeve and lamp.
Can a UV water filtration system be used on rainwater tanks?
Yes, selected UV filtration systems can be used for rainwater and tank water where the product is suitable. Rainwater setups should be assessed carefully because filtration needs can depend on tank condition, roof collection, sediment load, pump setup, water clarity, UV sizing and how the water is used throughout the home.
Can a UV water filtration system be used on mains water?
Yes, UV filtration can be used on mains water as an added layer of water treatment. Many homes choose a UV system as part of a whole-home filtration package where they want sediment reduction, taste and odour improvement from carbon filtration, and additional UV treatment in one system.
Does UV filtration make water taste better?
UV treatment itself does not usually improve taste or odour. Taste and odour improvement generally comes from the carbon filtration stage in the system. A combined sediment, carbon and UV system can help improve overall household water quality while also adding UV treatment.
Does UV water filtration use chemicals?
No. UV filtration treats water using ultraviolet light and does not add chlorine, salt or chemicals to the water. The water simply passes through the UV chamber while the lamp is operating.
Will a UV system work during a power outage?
No. UV systems need electricity to power the UV lamp. If the power is off, the UV treatment stage will not operate. Homes relying on UV treatment for rainwater or untreated water should consider this when planning the overall water treatment setup.
How often does a UV lamp need replacing?
UV lamp replacement depends on the system and manufacturer recommendations, but many UV lamps are replaced every 12 months. Even if the lamp still appears to glow, the UV output can reduce over time, so scheduled replacement is important for ongoing performance.
How often do UV system filter cartridges need replacing?
Cartridge replacement depends on the system, cartridge type, water usage and water quality. Homes with rainwater, tank water, heavy sediment, high usage or discolouration may need more frequent cartridge changes. Always follow the product recommendations and replace cartridges when flow or performance drops.
Where is a whole-home UV filtration system installed?
Whole-home UV filtration systems are usually installed near the incoming water supply before the water branches off to the rest of the home. The exact location depends on pipework access, power supply, available space, service clearance, drainage, weather exposure, pump setup and whether valves or bypass pipework are required.
Can a UV water filtration system be installed outside?
Some UV systems can be installed outside if the unit and installation position are suitable, but not every system should be exposed to weather. Enclosed systems or protected installations are often preferred where the filtration system is installed externally.
What is the difference between an open UV system and an enclosed UV system?
An open UV system usually has visible filter housings and UV components mounted to a bracket or frame. An enclosed UV system houses key components inside a protective cabinet-style casing, which can create a neater finish and help protect the system depending on the installation location.
Will a UV water filtration system affect water pressure?
Any whole-home filtration system can affect flow or pressure if it is undersized, blocked, incorrectly installed or fitted with cartridges that are not suitable for the home’s demand. UV systems should be selected based on flow rate, household usage, water pressure, pipework size and the required treatment level.
Can I buy a UV water filtration system supply only?
Yes. Choose supply only if you already have a licensed plumber or suitable installer arranged. Supply-only pricing is for the UV water filtration product only and does not include installation, valves, fittings, pipework changes, electrical work, pressure limiting valves, bypass valves, drainage, old system removal or compliance upgrades unless selected separately.
Can I order a UV water filtration system supplied and installed?
Yes. Supplied and installed options are available for selected ultraviolet UV water filtration systems in eligible Brisbane and Gold Coast service areas. Availability depends on your address, water supply, access, pipework, pressure, installation position, selected system and site requirements.
Does installation include electrical work?
Electrical work is not automatically included unless clearly shown in the selected installation option. UV systems require a suitable power supply nearby. If a new power point, electrical alteration or other electrical work is required, this may need to be arranged separately with a licensed electrician.
Does installation include pipework changes or extra valves?
Pipework changes, extra valves, pressure limiting valves, bypass valves, fittings, drainage alterations, wall mounting, difficult access work and other upgrades are not automatically included unless shown in the selected installation option or chosen as an add-on. Site requirements can vary between homes.
Which UV filtration system should I choose?
Choose an economy entry UV system if you want a practical starting point for whole-home UV filtration. Choose a premium full-coverage system if you need stronger flow capacity and higher household demand. Choose a premium enclosed system if you want a neater, more protected unit with a cleaner installation finish.
