Perth’s Water Filtration Specialists

Nothing tastes better than fresh home filtered water.

Did you know, for less than 5c per litre your entire family can enjoy crystal clear and chemical free water right out of your own taps?

Over the last 20 years we have noticed that the quality of Perth drinking water has declined. There have never been more chemicals than there are today, including chlorine and fluoride, plus many hidden dangers the general public is unaware of. Just think about all that water sitting in pipes that are 50+ years old. It travels through all those pipes and connections from the source to your home. This very long journey degrades the initial quality and causes your water to pick up other toxins like ammonia, copper, and barium.

How can you change this?

This is where a water filtration system from WestOz Water Filters will clean your water, removing toxins and other contaminants before it reaches your glass. Our water filtration systems are industry leading and can be used at home, in the office, as well as on the farm.

We have been installing water filter systems all over Perth and Western Australia for many years.  Our wide range of filters meets the needs for any size home or business. We have also developed a range of camping,  motorhome & caravan water filters to ensure safe drinking water for when you are travelling.

What our clients say…

The only thing I have purchased off WestOZ water filters is a two-bob water valve for my existing under sink water filter system which I purchased from another company, I called the other company for assistance but after three days I needed an answer as it was leaking. Sent Westoz a message from their website, Mavis called me within the house, Rob had the part ready for me, Showed me how to fit it, problem fixed in no time at all. Still haven’t heard from the other company, despite emails and phone call.

Great service – thanks heaps for your time.
