Reverse Osmosis Water Filter Systems for Sydney Homes
For households seeking the highest possible standard of water purity, a reverse osmosis (RO) system is the most advanced filtration solution available. At Full House Water Filtration, we specialise in supplying and installing premium RO systems designed for Sydney families, units, and residential homes.
Reverse osmosis removes up to 99.8% of contaminants, including fluoride, PFAS, dissolved solids, salts, chemicals, micro-contaminants, and heavy metals, delivering clean, safe, and incredibly pure water straight from your tap.
Why Choose a Reverse Osmosis Water Filter?
A professionally installed RO system forces water through an ultra-fine membrane that filters down to 0.0001 microns, removing contaminants that standard filters cannot.
RO is ideal for:
- Units & apartments (the only filtration option when whole-house systems cannot be installed)
- Families wanting ultra-pure drinking water
- Cooking, teas, coffee, baby formula, and washing fresh produce
- Homes concerned about fluoride, PFAS, and chemical exposure
- Health-conscious households that prefer alkaline, mineral-rich water
Reverse osmosis is considered the gold standard for drinking water quality.
How Our Reverse Osmosis Systems Work
A residential RO system includes multiple filtration stages:
1
Sediment Filtration
Removes dirt, rust, sand, and large particles.
2
Carbon Filtration
Reduces chlorine, chemicals, and odour.
3
RO Membrane (0.0001 microns)
Removes fluoride, PFAS, heavy metals, dissolved solids, nitrates, micro-contaminants, salts and fine impurities.
4
Remineralisation & Alkaline Filter
Adds essential minerals back into the water. Raises pH to 8–9.5 for healthier, smoother-tasting drinking water.
5
Oxygenation/Polishing Filter
The final stage that enhances oxygen content and taste freshness.
The Hidden Heavy Metals in Tap Water (and Why Only RO Removes Them)
Most people turn on their tap every day without realising what’s actually in their water. Even clear, clean-looking tap water can contain heavy metals such as:
- Lead
- Copper
- Chromium
- Arsenic
- Aluminium
- Cadmium
- Traces of mercury
You can’t see, smell, or taste these metals, but your body absorbs them every single day.
These metals don’t just sit quietly in your system. They affect your mood, energy, cognition, skin, and long-term health.
- Lead and mercury can cause irritability, anxiety, and behavioural changes.
- Aluminium and copper contribute to brain fog and poor concentration.
- Arsenic, cadmium, and chromium accelerate ageing by damaging your cells and organs.
A standard whole-house filter cannot remove these metals — it only reduces chlorine, sediment, and some PFAS.
But the good news:
Reverse Osmosis is the only filtration method that removes heavy metals almost completely before they reach you or your family.
If you want cleaner, safer, healthier water — RO is the system that protects your family at the deepest level.
RO Systems in Units & Apartments: Important Note
RO is the only suitable filtration option for:
- Units
- Apartments
- Townhouses with shared water meters
- Rental properties
Whole-house systems cannot be installed in units because they require a private water meter.
RO installs neatly under the kitchen sink and is perfect for smaller living spaces.
