Upgrade your kitchen with our range of high-performance undersink water filters, specifically selected for Australian tap and tank water conditions. From space-saving multi-acting systems to twin-stage systems and advanced Reverse Osmosis (RO) filtration, our units remove chlorine, fluoride, heavy metals, PFAS and sediment without cluttering your benchtop.
Our systems are designed for durability and feature WaterMark certified components to ensure compliance with Australian plumbing standards. Whether you’re looking for a dedicated filtered tap or a high-flow integrated solution, enjoy pure, great-tasting water directly from the source.

Choosing the Right Undersink Water Filter for Your Home
Selecting a water filtration system in Australia depends largely on your water source—whether you are on treated town water in Sydney, or relying on rainwater tanks and bore water in regional areas. While municipal water is safe, it often contains chlorine and fluoride that affect taste and smell. Our undersink systems provide a “final polish,” ensuring your drinking water is of the highest possible quality.
Twin-Stage vs. Three-Stage vs. Reverse Osmosis
When browsing our range, you’ll notice different levels of filtration:
-
Twin-Stage Systems: Usually consist of a sediment filter and a high-quality carbon block. These are ideal for removing dirt, rust, and the heavy taste of chlorine.
-
Three-Stage Systems: Add an extra layer of “polishing” or a specialized filter for specific issues like heavy metals or extra-fine sediment.
-
Reverse Osmosis (RO): The gold standard for purity. RO systems use a semi-permeable membrane to remove up to 99% of all contaminants, including fluoride, nitrates, and “forever chemicals” (PFAS).
Frequently Asked Questions
Do I need a plumber to install an undersink water filter?
While many of our systems feature “quick-connect” fittings that are DIY-friendly, we recommend professional installation by a licensed plumber to ensure compliance with Australian plumbing standards. This also ensures your system is fitted with a pressure-limiting valve to protect against water pressure spikes.
How often should I change my filter cartridges?
For most Australian households, we recommend replacing your undersink cartridges every 6 to 12 months. This ensures the carbon remains effective at absorbing chemicals and prevents bacteria build-up within the housing.
What is WaterMark Certification and why does it matter?
The WaterMark Certification Scheme is a mandatory certification for plumbing and drainage products in Australia. All our undersink systems utilize WaterMark-certified components, giving you peace of mind that the system is safe, durable, and legal to install in your home.
Why are NSF/ANSI international standards important?
While WaterMark confirms a system is safe to connect to your plumbing, NSF Certification is what verifies the actual filtration performance. When a filter is NSF certified, it has undergone rigorous independent testing to prove it removes the specific contaminants claimed on the label.
