The Aqualith SolutionPremium Three-Stage Filtration for Your Whole Property.
Sediment & Fine Particles
The first stage traps sand, silt, and rust particles before they ever reach your household plumbing, so every stage after it starts with cleaner water.
Scale & Mineral Build-Up
The second stage helps control scale, iron and hydrogen sulfide, protecting fixtures and extending the life of anything that handles water daily.
Chlorine, Taste & Odour
Coconut shell activated carbon holds roughly 50% more micropores than standard carbon, giving it more surface area to remove chlorine, taste and odour.
Whole-Home Water Protection
Installed at the point water enters the property, the system treats every tap, bathroom and appliance downstream in one pass.
One Filtration System.
Whole-Home Coverage
Most households only think about water quality at the kitchen tap. But the same sediment, chlorine, and mineral content affecting your drinking water is also passing through your shower, your washing machine, and every appliance connected to the mains.
Because the Aqualith Triple Stage system is installed at the main water entry point, filtration happens once, upstream of your entire plumbing network, rather than at each individual tap.
It’s the difference between treating a symptom at one outlet and addressing the water itself before it ever reaches a fixture.

Frequently Asked Questions
A whole house water filtration system is installed on the main water supply line before water enters your property. This allows filtered water to reach every tap, shower, bathroom and laundry outlet throughout the home, rather than treating water at a single point of use.
Yes. The Triple Stages Big Blue Water Filtration System is designed for Australian homes, apartments, offices, lodges and restaurants. Its high-flow 20″ x 4.5″ cartridges are suitable for properties where multiple taps, showers and appliances may be used at the same time.
Australian tap water is treated to meet strict standards, but factors such as chlorine treatment, ageing infrastructure, local plumbing and regional water conditions can still affect taste, odour and overall water quality. Many homeowners install whole house water filtration systems to improve water quality throughout the property.
The system uses a three-stage filtration process designed to help reduce sediment, sand, dirt, rust particles, chlorine-related taste and odour, and other unwanted particles commonly found in residential water supplies. Filtration performance may vary depending on source water quality.
Filter replacement depends on water quality, household usage and operating conditions. For 20″ x 4.5″ whole house filter cartridges, replacement is commonly recommended every 12–18 months, although actual service intervals may vary. Regular maintenance helps ensure optimal filtration performance and water flow.
Big Blue systems use larger filter housings and high-capacity cartridges compared to standard residential filters. This allows higher flow rates, greater filtration capacity, and longer service life, making them a popular choice for whole-house water filtration applications in Australia.
