NSF Class A Certified UV protection for rain or bore water supplies
The UV filtration system VIQUA Pro20 is NSF/ANSI 55 Class A certified. This certification ensures the system delivers a minimum UV dose of 40 mJ/cm²—sufficient to inactivate harmful bacteria, viruses, and protozoa, such as E. coli, Cryptosporidium, and Giardia. NSF certification provides peace of mind that the Pro20 offers proven, reliable protection for your home or business water supply.
High-output amalgam UV lamp – Up to 3× more powerful than standard systems
The Viqua Pro20 UV filter uses a high-output amalgam UV lamp, which contains a stable mercury alloy instead of standard elemental mercury. This advanced design delivers up to three times the UV intensity of conventional lamps and extends the lamp life. As a result, there are fewer replacements and more consistent protection. As a result, it kills 99.99% of harmful microorganisms, including E. coli, Giardia, and Cryptosporidium.
Energy-efficient UV water filtration with LightWise™ technology
The Viqua Pro20 UV water filter features LightWise™ technology, which automatically dims the UV lamp during periods of low or no water flow, such as overnight or while you are away. This intelligent energy-saving function reduces power usage, minimises heat buildup, and extends the life of the lamp, helping lower your running costs. An excellent choice for eco-conscious households, this UV filter NZ delivers reliable protection without wasting energy.
Smart cooling design offer durability and easy maintenance
The Pro20 UV is built for long-term reliability, even in harsh NZ weather conditions. Its CoolTouch fan regulates internal temperatures, protecting vital components and extending the life of the UV lamp. The 316L stainless steel chamber is corrosion-resistant and designed to handle the daily demands of large households or light commercial settings. This combination of intelligent cooling and durable construction ensures consistent UV performance and minimal maintenance over time.
Improve UV performance with pre-filtration for your Viqua Pro20
To get the most out of your Viqua Pro20 UV water filter, we strongly recommend installing a sediment pre-filter. Particles such as rust, sand, and organic matter can block or scatter UV light, reducing the effectiveness of disinfection. Pre-filtration ensures clearer water for maximum UV exposure, helping to prevent buildup on the quartz sleeve and UV lamp and extending the life of your system while reducing maintenance needs.
Every water supply is different. Talk to our water experts on 0800 278 288 and we will pair your Pro20 with the perfect pre-filter for top performance and longitivtiy.
Stay informed with smart UV monitoring at a glance
The Viqua Pro20 UV system is designed for simplicity and peace of mind, featuring a smart digital display and built-in sensors that provide instant feedback on system performance. You'll always know if your UV lamp is working correctly, when it's due for replacement, and whether the system is operating at full disinfection strength. This intuitive interface keeps your water safe—no guesswork or technical expertise needed.

Steve's Pros & Cons
Pros of Viqua Pro 20 UV whole-house water filtration system
Rock-solid UV reliability – The Toyota of UV water systems in NZ
If you’re after something reliable and low maintenance, the UV filter Viqua Pro 20 is built to last, simple to run, and always ready to go. This drinking water filter system delivers reliable, chemical-free disinfection day in and day out, without the high maintenance other systems often need. It’s also energy efficient, so you won’t see a spike in your power bill just for having clean water.
Viqua Pro20 UV whole-house: Reliable UV performance, even on unstable power
In the past, ballast reliability was occasionally affected by fluctuations in New Zealand’s power supply, which is known to be unstable in some areas. However, the manufacturer has worked directly with us to resolve these issues, providing technical support and refining the product to better suit local conditions. Their responsiveness and willingness to adapt have resulted in a more robust, reliable UV filter system for New Zealand installations.
Professionally assembled Viqua pro UV system: Designed for local conditions
At Aquaworks, we’ve developed a custom rack-mounted water filtration setup that’s built to last and ready for the outdoors. It’s fully weatherproof and engineered specifically for New Zealand’s conditions, so there’s no need for extra housing or protection. The design is tidy, robust, and simple to install — making it a hassle-free solution for long-term use.
Built-in safety: Optional UV water system shut-off valve
For added peace of mind, an optional automatic shut-off valve can be installed with your UV system. If the UV lamp fails or stops functioning, this valve immediately halts the flow of water — preventing untreated water from entering your home. It’s an extra layer of safety that protects your household even when no one’s there to monitor the system.
The Viqua Pro 20 UV system offers flexible flow rate options to ensure every drop gets the correct UV dose for safe, effective disinfection. Don’t guess — get the right setup for your water volume and call Aqua Works now on 0800 278 288.
Cons of the Viqua Pro 20 UV whole-house water filtration system
Keep your UV water treatment system clean – UV doesn’t provide residual protection
UV systems work by disinfecting the water instantly as it flows through the unit. But they don’t leave any lasting protection in the pipes afterwards. So, if any bacteria or contaminants get into the water further down the line — like in old plumbing or a storage tank — the UV system can’t do anything about that. That’s why it’s important to make sure the rest of your whole-house UV system stays well-maintained too.
Viqua UV systems aren’t set-and-forget: Routine maintenance is needed
The UV lamp should be replaced every 12 months, because the UV intensity drops over time, even if you can’t see it. The quartz sleeve that surrounds the lamp also needs attention now and then. Over time, mineral deposits or sediment can build up on it, which blocks the UV light from doing its job properly. Keeping up with it is key to ensuring your water stays safe year-round.
Plastic end nut problems solved with durable metal upgrade for the UV filter Viqua Pro 20
In earlier versions of this UV water treatment system, the plastic end nuts were a known weak point — over time, they could become brittle, crack, or fail under pressure, especially in outdoor setups. To solve this, we now supply a robust metal end nut alternative that significantly improves durability and reliability. It’s a simple upgrade that eliminates a common issue and gives the system a longer, trouble-free lifespan.
Clear water is key – How turbidity affects the performance of your Viqua Pro20 UV system
The needs clear water to work effectively. If your water has high turbidity (cloudiness from sediment) or elevated iron levels, it can block or scatter the UV light, reducing its ability to disinfect properly. That’s why pre-filtration is so important — it removes the particles that interfere with UV treatment and ensures the system can deliver full-strength protection. It’s not a flaw in the unit, just a normal limitation of how UV disinfection works.
Aqua Works has been working with this leading UV brand for over 25 years. With reliable local support and fast access to parts through our NZ supply chain, you’re never left waiting. Call 0800 278 288 and get trusted UV protection that stands the test of time.
