EUROPEAN RESEARCH AND DESIGN

A Superior Water Filter System

At Osmosis Water Filters Perth, we believe that superior water quality should be the standard, not the exception, in every Perth home.

Our approach is different: we don’t rely on generic, one size fits all solutions. We partner exclusively with BWT (Best Water Technology), Europe’s leading water treatment innovator, to bring their world class filtration and anti scale technology directly to Western Australia. This synergy allows us to combine BWT’s decades of global R&D excellence and proven engineering with our own meticulous, Perth specific water analysis, ensuring the system installed in your home is perfectly calibrated to tackle our unique challenges from local hard water and mineral content to chlorine taste and sediment.

With Osmosis Water Filters, you get a system that delivers guaranteed quality, backed by the best in the world, and installed by the best in the west.

The hidden dangers in Perths Water

The Facts Behind Perth’s Tap Water

High Hardness Levels:
Perth registers some of the highest water hardness in Australia, often ranging from 120 mg/L to over 200 mg/L in some suburbs (classified as “hard” to “very hard”). This mineral rich water is the primary cause of limescale and appliance damage.

The Chlorine Compromise:
A higher reliance on long-distance pipe networks requires more aggressive disinfection. The resulting chlorine taste and odour are not just unpleasant for drinking, but the vapours released during hot showers can irritate skin and lungs.

Financial Impact:
Hard water scale buildup inside appliances like hot water systems can reduce their efficiency by up to 30%, leading to higher quarterly energy bills and significantly shortening their lifespan.

Aesthetic Residue:
The mineral content leaves unsightly chalky white spots and film on shower screens, tapware, kettles, and glassware, demanding constant, aggressive cleaning.

How Safe Is Your Homes Drinking Water?

CLEAN PURE WATER FROM EVERY TAP

Whole Home Filtration Systems

We didn’t simply import a generic filter; we worked closely with BWT to help engineer a system proven to tackle Perth’s specific contaminants.

Our comprehensive Whole House Filtration System is built on a high flow, two-stage process that targets the core issues without compromising your water pressure:

Chlorine, Chemical and Sediment Removal:
Water passes through our industrial grade, multi-layer carbon filter. This advanced media provides a large surface area to adsorb up to 99% of chlorine, sediments, rust, and other organic compounds.

Odour Free & Beautiful Tasting
The result is truly pure, soft water from every tap, perfect for drinking, cooking, and ensuring healthier skin and hair for your entire family.

Purezone Premium

Say goodbye to messy filtration setups.

The PureZone Filter is a premium dual-stage filtration system, combining sediment protection and activated carbon in one sleek enclosed housing. It helps reduce dirt, rust, chlorine taste, odour and discolouration before the water reaches your household taps.

With its fully contained cover, you get a clean, modern installation — no exposed pipes or messy housings.

Automated Purezone

Say goodbye to cartridges.

The Automated PureZone delivers whole-home filtration using a long-life carbon media bed that automatically refreshes itself.

It helps reduce chlorine, odour, organic compounds and discolouration — all without ever swapping filter cartridges.

Pearl Water Softener

Say goodbye to scale stained showers

The Pearl Water Softener treats hardness minerals, helping protect your hot water system, fixtures and appliances.

Enjoy softer skin and hair, streak-free glass, brighter tiles and longer-lasting plumbing.

Cleaner bathrooms, softer water, and less scrubbing—every day.

Water Tank Filtration Systems

For homes relying on rainwater tanks, bore water, or other private sources, filtration alone is not enough—you need guaranteed microbiological safety. That’s why Osmosis Water Filters offers the advanced BWT Ultraviolet (UV) Disinfection System, engineered to provide a crucial line of defence against unseen biological threats.

Chemical-Free Sterilisation:
The BWT UV lamp instantly neutralises 99.9% of harmful pathogens, including E. coli and Giardia, without altering the water’s taste, colour, or odour.

Essential Health Protection:
This system is critical for ensuring that all water used inside your home—for drinking, washing produce, or brushing teeth—is microbiologically safe for the entire family.

Compact & Reliable:
Designed for residential applications, the BWT unit is compact, energy-efficient, and features an integrated monitoring system to ensure the lamp is always operating effectively.

The Regional Solution:
Perfect for homes in Regional WA or outer suburbs where scheme water is unavailable or where tank water purity is a continuous concern.

Purezone UV

Say goodbye to bacteria and unsafe household water.

Harnessing the power of ultraviolet light, this unit acts as a natural and chemical free solution to disinfecting mains water and provides an enhanced water experience.

Servcing Perth and Regional WA

As a family owned and operated Perth business we take immense pride in helping one Perth family at time experience the benefits of pure filtered water. It is with this joy that we now also offer a regional WA supply service.

Perth Metropolitan  (Scheme Water Focus)

Osmosis provides a complete installation service

For Perth homeowners, our system provides relief from the common aesthetic issues like harsh chlorine taste and limescale buildup caused by the city’s reliance on hard groundwater and desalinated sources. We focus on protecting your appliances and delivering better-tasting water from every tap.

Regional WA & Bore Water Service (Contaminant Focus)

Osmosis provides a supply statewide so you can organise your local plumber

We understand that regional WA often faces different, more complex water challenges, including higher levels of sediment, iron, and bore water contaminants. We offer specialised BWT-powered configurations tailored for:

Bore Water: Advanced filtration to handle high mineral and metal content.

Tank Water: UV options to ensure microbiological safety and purity.

Scheme Water: Solutions that address localised issues not seen in the metro area.

Frequently Asked Questions

Our philosophy is to provide the most efficient and effective solution, specifically engineered for Perth’s mains water. Through our research and partnership with BWT, we found that two high-quality stages are all that is needed: Stage 1: Limescale & Hardness Control and Stage 2: Carbon Block for Chlorine & Sediment Removal. More stages often mean unnecessary complexity, restrictive flow rates, and higher replacement costs without providing any extra benefit for the contaminants found in Perth’s scheme water. We focus on premium quality, not stage quantity.

BWT stands for Best Water Technology, and they are the leading water treatment specialists in Europe. By white-labelling their systems, Osmosis Water Filters brings you globally-proven engineering and premium, patented filter media.
