Choosing the right water filter for your Townsville home
The right water filtration system depends on where your water comes from:
- Town water: a whole-house filter improves taste and odour and removes sediment at every tap.
- Bore water: often needs a water softener for hardness, and sometimes reverse osmosis for salty or high-mineral water.
- Rainwater: a whole-house filter removes sediment and debris from tanks and roofs.

Home water treatment
What your filter catches
Pick where your water comes from, then switch treatment stages on and off. Watch what gets caught in each cartridge, what goes down the drain, and what ends up in your glass.

In your glass
Faint bar: before. Solid: after. Tap a row for details and to track it.
The five stages
Who catches what
Levels shown for each source are typical patterns, not a test of your water. Bores and dams in particular vary a lot between properties, so get a lab test before buying equipment.
Removal depends on the product. Carbon results assume a good-quality carbon block; chloramine needs catalytic carbon. Sediment only catches parasites at 1 micron absolute rating. RO removes most germs but is not relied on as a disinfection step. Look for WaterMark and AS/NZS 4348 certified products.
Maintenance intervals are typical ranges; follow the manufacturer’s schedule.

Replacement water filters and cartridges
We supply replacement water filter cartridges in Townsville for home filters, under-sink units and reverse osmosis systems, including systems we did not install. Changing cartridges on time keeps your water tasting right and stops a blocked or spent filter letting contaminants through.
- Sediment cartridges: catch dirt, rust and silt. Standard and large (big blue) housings.
- Carbon cartridges: remove chlorine, taste and smell.
- Reverse osmosis membranes and pre-filters: for cabinet, under-sink and whole-house RO units.
- UV lamps and quartz sleeves: for UV disinfection on tank and bore water.
Not sure which cartridge you need? Send us a photo of your old cartridge and the filter housing, or the brand and model of your system, and we will match it. Ask for replacement filters using the form below and tick “Replacement filters and cartridges”.

Why choose a local Townsville water filter supplier
Buying from a local supplier means advice from people who know North Queensland water, and someone nearby when a cartridge needs changing or a system needs a service. Our team works with town water, rainwater tanks and bore water every day, from homes to mine sites, and we test the water, with analysis by a NATA-accredited laboratory, before we recommend a filter.

Water filter FAQs
How much does a water filter cost in Townsville?
A whole-of-house filtration system starts from $2,255 inc GST (supply only). Prices correct as at October 2026 and may change. Every home is different, so we quote after checking your water. Request a quote for a price for your home.
What type of home reverse osmosis system do you supply?
A cabinet reverse osmosis unit that supplies filtered drinking water to a dedicated tap. We supply and install them across Townsville, and also supply replacement cartridges and membranes for under-sink filters and RO units, including ones we did not install.
What is the difference between a water softener and reverse osmosis?
A softener removes hardness minerals from all the water in the house to stop scale. Reverse osmosis treats a single tap, usually the kitchen, and removes most dissolved salts and contaminants for drinking. Many homes on hard water use both.
Can bore water be made drinkable?
Often, yes, with the right filtration and reverse osmosis. It depends on what is in your bore, so a water test comes first.
How often do the filters need changing?
It depends on your water and the system. As a guide, sediment and carbon cartridges are changed every 6 to 12 months, reverse osmosis membranes every 2 to 3 years, and UV lamps every 12 months. We will give you a schedule for your system and can supply the replacement cartridges.
Do you sell replacement water filter cartridges?
Yes. We supply replacement sediment and carbon cartridges, reverse osmosis membranes and pre-filters, and UV lamps for home systems in Townsville, including systems we did not install. Send us a photo of your old cartridge or the brand and model of your system and we will match it.

What is the difference between a water filter and a water softener?
A water filter removes particles, sediment, and taste and odour from your water. A water softener removes the hardness minerals that cause scale on taps, showers and hot water systems. Many homes on bore water use both.
