Rainwater can be relatively clean but by the time it travels across your roof, gutters into your water tank, it can pick up nasties that are not always visible to the eye.
Along this journey, the water can pick up sediment, bacteria, bird droppings, tannins and other contaminants such as:
- Sediment and dirt — dust, sand, and debris washed from your roof
- Bacteria — including E. coli and Salmonella from bird and animal droppings
- Tannins — from decaying leaves in gutters, causing a yellow or tea-like colour
- Fine particles — that affect taste and clarity
This doesn't mean your tank water is dangerous as many Australians drink rainwater safely every day. But a proper filtration system gives you peace of mind and protects your family, your appliances and your plumbing.
How to get started with water filtration
There are two main approaches depending on how much of your water you want treated and your budget.
-
Whole House Filtration
Installed where your main water line enters your home — every tap, shower, and appliance receives filtered water, not just your kitchen tap. -
Under Sink Filtration
Installed beneath your kitchen sink, treating water at a single dedicated drinking tap. A more affordable entry point into rainwater filtration.
View the guide below to help you make a decision:
| 🏠 Whole House Filtration | 🚰 Under Sink Filtration | |
|---|---|---|
| What it does | Filters all water entering your home — every tap, shower, appliance, and hot water unit. | Filters water at a single point — usually a dedicated drinking water tap at your kitchen sink. |
| Best for | Homes on rainwater as their primary supply who want complete protection throughout the home. | Homeowners primarily focused on drinking water quality, or those looking for a cost-effective starting point. |
| Benefits | Protects pipes and appliances from sediment, improves shower water, and ensures every outlet delivers clean safe water. | More affordable upfront, easy to install, and delivers clean filtered drinking water on demand. |
| Ideal if... | Your family relies entirely on tank water day to day and you want whole-of-home peace of mind. | You maintain your tank well and mainly want safer, better tasting drinking water at the tap. |
