Under Sink RO vs Whole House Water Filter Australia
Understanding The Difference Between These Two Systems
One of the most common questions homeowners ask is whether they should install an under sink reverse osmosis system or a whole house water filter.
The answer depends on what you want to improve. While both systems filter water, they solve very different problems.
An under sink reverse osmosis system focuses on producing high purity drinking water from a single tap. A whole house water filter improves water quality throughout the entire home, including showers, bathrooms, laundry, and kitchen taps.
Understanding the role of each system makes choosing the right setup much easier.

What An Under Sink Reverse Osmosis System Does
A reverse osmosis system is installed beneath the kitchen sink and filters water at the point where you drink and cook.
The ES3 Reverse Osmosis System uses multiple filtration stages and a specialised membrane to remove contaminants such as chlorine, fluoride, dissolved solids, heavy metals, and other impurities.
This level of filtration produces cleaner tasting and higher purity drinking water than standard carbon filters.
Many homeowners choose reverse osmosis because they want more control over the quality of the water they consume every day.
What A Whole House Water Filter Does
A whole house system works differently. Instead of filtering one tap, it filters water before it enters the home.
This means every tap, shower, and appliance receives filtered water.
A Whole House Water Filter is designed to reduce chlorine, sediment, dirt, and build up while improving overall water quality throughout the home.
The benefits extend far beyond drinking water. Homeowners often notice softer feeling water, reduced chlorine smell, cleaner showers, and less stress on plumbing and appliances.
Which System Is Better For Your Home
If your main concern is drinking water quality, reverse osmosis is the better choice. It provides deeper filtration and is specifically designed for high purity water used for drinking and cooking.
If your priority is improving water quality across the entire home, whole house filtration is more suitable.
Many Australian households eventually combine both systems because they solve different problems together.
A whole house filter improves the water you shower and wash in, while reverse osmosis provides the highest quality drinking water at your kitchen tap.
Why Many Homeowners Combine Both Systems
Using both systems together gives homeowners complete coverage.
A whole house system filters water entering the property, reducing chlorine and sediment before it reaches your taps. Reverse osmosis then provides an additional layer of deep purification for drinking water.
This setup delivers:
- Clean water at every tap
- Better tasting drinking water
- Reduced chlorine exposure
- Protection for plumbing and appliances
- Long term convenience and value
