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.
