Why Choose a UV Water Filter?
Traditional filters remove dirt and sediment, but can’t kill micro-organisms. UV water filters use ultraviolet light to disinfect water safely and effectively, destroying harmful pathogens such as E.coli, Giardia, and Cryptosporidium.
Because UV treatment doesn’t use chemicals, it leaves your water clean, clear, and natural-tasting. It’s an environmentally friendly solution trusted by New Zealand households, schools, rural properties and commercial businesses.

Maintenance and Servicing UV Water Filters
UV systems need proper annual servicing to stay effective. Lamps lose strength long before they look dim, and quartz sleeves quickly build up deposits that reduce UV performance. Correct flow rates and clean pre-filters are essential. Aqua Works provides expert servicing for all major brands — including Sterilight, Viqua and Puretec — to ensure your system continues to deliver safe, reliable disinfection.
How UV Water Filtration Works
A UV lamp is housed inside a stainless-steel chamber. As water passes through, ultraviolet light penetrates the cells of bacteria and viruses, rendering them harmless.
The process takes just seconds and doesn’t affect water pressure, colour, or flavour. UV purification is a continuous safeguard that works automatically whenever you turn on the tap.
FAQ about UV Water Filters
What does a UV water filter remove?
UV water filters kill microorganisms such as bacteria, viruses, and parasites. They don’t remove sediment or chemicals, so a pre-filter is recommended for best results.
Water is our most important food. Microorganisms such as algae, protozoa, bacteria and viruses, nitrates, heavy metals, copper, hormones, fluorides, pesticides and herbicides in your drinking water will damage your health even in small quantities.
Aqua Works offers you the perfect solution for providing your body with safe, healthy drinking water now and in the future. Our UV filter systems kill 99.99% of viruses and bacteria without using chemicals.
Does a UV water filter work with rainwater tanks or bores?
Absolutely. UV systems are ideal for rainwater, bore, and rural water supplies, providing constant disinfection at the point water enters your home.
If you are building a new house or have bought a rural lifestyle block and want to enjoy healthy water from every tap, a UV Water Filter is required for safe drinking.
Can you upgrade the system we have in an existing house?
Yes, we can. Aqua Works can retrofit your household water filter system. When you choose UV purification, drinking water will be safe from every tap in your home.
Do UV water filters affect water pressure?
No. When properly sized for your water flow, UV systems maintain normal household water pressure.
What happens if we have a power cut?
UV systems require power to operate. During a power cut, untreated water should not be used until the UV system is back on.
How often should the UV lamp be replaced?
The UV lamp should be replaced every 12 months. Even if the light still appears to work, its UV intensity decreases over time.
Why do I need UV water purification?
Water is our most important food, and it naturally contains bacteria. Much of it is harmless, but some microorganisms multiply rapidly under certain conditions and become a severe problem for your health. If you are on rainwater, groundwater, tank water or service water, you will be likely exposed to an increased level of bacteria, germs and viruses.
The rain washes faeces of birds and occasionally possums, insects, snails, dust, pollen, moss, lichens, mould and debris from the roof of your house into the water tank. Bacteria such as E.Coli and protozoa like Giardia thus enter your water system and pose a serious risk. From our long experience, we know that 70% of rainwater tanks are contaminated.
How does UV water disinfection work?
UVC or UV disinfection means killing or inactivating pathogenic microorganisms (bacteria like E.Coli). This chemical process uses UV radiation in the wavelength range of 254 nM. UV radiation works quickly and safely and is an effective, economical process that has been on the market for a long time. UV-C light is used for UV disinfection to treat domestic water for drinking water, well water, ponds and swimming pools.
UV light kills viruses, bacteria & germs
Ultra Violet (UV) disinfection sterilises water up to 99.99%. This way, UV disinfection is a reliable and harmless way of killing viruses, bacteria and germs of all kinds. And entirely without the addition of chlorine or other chemicals To enjoy healthy, fresh drinking water every day, a professional should service the entire water system at least once a year.
