UV Water Filter Systems
for Rainwater Tanks
If your household relies on rainwater, you probably know it’s not as clean as it looks. Leaves, dust, bird droppings, and microbes can all end up in your tank, even if your water looks clear. The result? Contaminated water that could be unsafe to drink, cook with, or even shower in.
At PureFlow, we specialise in UV water filter systems designed specifically for Australian rainwater tanks. Our 3-stage rainwater tank filtration setup combines sediment removal and powerful ultraviolet light treatment, delivering safe, clean water without chemicals or complexity.
Benefits of Rainwater Filtration
Filtering your rainwater before it enters the home is a simple step that makes every tap safer.
Health
Rainwater isn’t treated like mains water, so without proper filtration, it may contain pathogens, sediment, and contaminants from bird droppings, leaves, or rust. A multi-stage rainwater filter helps make tank water safer to drink, cook with, and bathe in.
Home Protection
Unfiltered tank water can cause sediment buildup, pipe corrosion, and damage to washing machines, dishwashers, and kettles. A filtration system keeps your home’s infrastructure clean and running efficiently.
Sustainability
Filtered rainwater reduces your environmental footprint and gives you greater water security, especially in rural or off-grid properties. Use it confidently for your family, garden, or even emergency supply.
What is a UV Water Filter System?
A UV water filter is a disinfection system that uses ultraviolet light to neutralise bacteria, viruses, and other pathogens in water. It doesn’t use chlorine, salt, or chemicals, just light.
UV systems are commonly installed at the point where tank water enters your home, ensuring all water used in the kitchen, bathroom and laundry is treated.
For UV to work properly, the water needs to be free from sediment or cloudiness, which is why we pair it with multi-stage pre-filtration as standard.
Why Filtration Before UV Matters
One of the most common misconceptions is that UV alone is enough. In reality, ultraviolet light can only treat clear water. If there’s debris, dirt or organic matter floating in the water, the UV light can’t reach and deactivate the microorganisms properly.
That’s why we use a three-stage approach:
- 20-micron sediment filter – captures larger particles like rust, leaves, and sand
- 5-micron polyspun filter – removes fine dirt, silt and remaining sediment
- UV light disinfection – neutralises bacteria, viruses and parasites without affecting water taste or pH
This process ensures that water is not only clean, but safe, all without relying on chlorine or additives.
For added chemical reduction, you can replace either sediment stage with an optional carbon cartridge.

How PureFlow’s 3-stage UV Water Filter Works
Our 3-stage UV water filer uses a combination of physical filtration and UV disinfection to treat tank water effectively:
Stage 1
20-Micron Pleated Sediment Filter
Removes larger particles such as rust flakes, suspended solids, leaves, and sand. The pleated design increases surface area for better performance and lifespan.
Stage 2
5-Micron Polyspun Filter
Captures finer debris missed in stage one - including silt, fine dirt, and smaller rust particles - ensuring high-clarity water before UV treatment.
Stage 3
Advanced UV Disinfection
Neutralises bacteria, viruses, and pathogens like E. coli using ultraviolet light. This non-chemical disinfection step makes your tank water safe for drinking and cooking.
Our domestic UV water filter system is made in Italy and built for the unique demands of Aussie tank setups. It can handle up to 70 litres per minute, making it suitable for small to medium-sized households.
- Certified to Australian standards
- Can be installed before or after your pump
