Bunbury & Perth Metro REVERSE OSMOSIS SYSTEM
Standard Filters Cannot Remove Everything
Carbon filtration handles chlorine, sediment, and heavy metals well. But it has limits. Fluoride, PFAS, microplastics, dissolved salts, pharmaceuticals, and trace contaminants require a different level of treatment entirely.
Reverse osmosis is the only system we offer capable of targeting these ultra-fine dissolved contaminants, removing up to 98-99% of what carbon filtration leaves behind.

What Our Customers Say
Outstanding install and remarkable water improvement
We recently had a whole-house water filtration system installed by West Coast Water Filter Man, at our home in Melville and the entire experience has been outstanding. Dan, the plumber who completed the installation, was an absolute legend—professional, efficient, and clearly knowledgeable. Richard was honest and reliable throughout the process, making everything straightforward and stress-free. After three weeks of use, the difference in our water quality is remarkable. The system works perfectly, and we couldn’t be happier with the result. Highly recommended to anyone looking for great service and even better water

Clean water benefits proven at home
I’ve recently stepped into the family business, opening the regional branch of West Coast Water Filter Man, while Dad continues to run the Perth Metro branch. After 25+ years of WCWFM looking after WA homes, I couldn’t be prouder to now play a bigger role in keeping that tradition alive. And I don’t just sell our systems — I stand behind them myself. At home, I’ve got a Whole of House Triple Filtration System with a Delta Diamond Water Conditioner and a Twin Under-Sink Filtration System. The difference it’s made in my own home has been massive: ✅ My partner has noticed softer skin, less dry hair, and reduced eczema symptoms ✅ Showers feel cleaner and fresher without that chlorine sting ✅ Drinking water no longer smells or tastes like dirt or chlorine — it actually tastes clean ✅ Appliances and glassware stay clearer, with far less staining and scale. It’s one thing to hear feedback from customers every day, but it’s another to live the results myself. That’s why I can honestly say our products and service aren’t just “good for business” — they’re good for families, health, and homes all across WA. — Syd Scholes

Knowledgeable, punctual, softer water results
We are thrilled with the quality and softness of the water since having had the water filters installed. The service from Richard and his team was amazing. Richard was really great to deal with. His knowledge of the products was really helpful but most importantly he kept us informed as to when the installers would be arriving and they were always on time. No hesitation in recommending West Coast Water Filter Man. You can’t stay in business for 25 years unless you are doing something right and Richard certainly is proof of that. Gina and Richard Gale

Clear install and noticeably better water
We are extremely happy with the service from Richard and his team. From the very first request everything was clear, straightforward and easy to understand. On the installation day, they arrived on time and worked efficiently and professionally. The whole process was smooth, stress free and clean. They did an excellent job! Most importantly we absolutely love the water quality now! Feels and tastes way, way better and smooth. We are very satisfied from start to finish and would highly recommend West Coast Water Filter Man!
Arcadia
Noticeable water quality within days
Amazed at the difference in water quality, even though it’s only been a few days since install. The guys, Richard and Dan, not only completed the install in a timely manner, but left the area clean and tidy. The actual unit blends in perfectly within the area. From initial contact to install was less than a week, our choice otherwise it could have been a lot sooner. The water quality is very noticeable, from drinking to clothes washing. From our family, sincere thanks to all at West Coast Water Filter Man for making the experience so easy. If you are thinking of home water filtration, we can highly recommend without reservation West Coast Water Filter Man. Sincere regards, Kim & Lana

Fast booking, harsh water now gone
A great job and well done!!! Thank you Richard and team for installing the Whole House Triple Filtration System and Delta Diamond Magnetic Water Conditioner for mum and I. From the initial contact organised through a family referral to complete install Richard gave me 100% genuine and professional service. Installation was booked fast and efficient as I was eager to have it done ASAP. Even after install I was responded to quickly. I can confidently say I will be sending out recommendations for the good deeds provided by Richard… so happy. Water tastes amazing and feels so much better… no more harsh, smelly water!!!

Thorough workmanship with no follow-up needed
I had an excellent experience with West Coast Water Filter Man having my whole-house water filter installed at my home in Clarkson. Richard and Dan took the time to complete the job properly and did not rush any part of the installation. Their workmanship was extremely thorough, and they ensured everything was done correctly the first time, with no need for follow-up checks. Their attention to detail, professionalism, and commitment to quality truly stood out. I highly recommend them to anyone looking for reliable and high-standard water filtration services.

Whole-house system, softer water, great install
We love our new Whole of House Triple Filtration System and Delta Diamond Magnetic Water Conditioner, the service from Sydney in the beginning was fabulous and the installation by Dan and Richard was excellent, they took the time to work out the best position and explained everything in detail. The whole family have noticed the difference in water quality, mainly a much softer feel and better tasting. I’m also looking forward to the benefit of lower maintenance to tapware, shower screens, grouting etc. Highly recommend the West Coast Filter Man team. I’m also in the process of having the same unit installed at my rental property in Jurien Bay.

Best investment for my forever home
The best investment for my forever home – whole house and under sink filtration. The water is just awful in my area, hard, smelly and full of nasties that stain and clog up showers, and appliances, including my hot water system and air-conditioner. After looking around I was fortunate to have ended up with the amazing, no pressure advice on the best system I could get for my home, from West Coast Water Filter Man. I believe I now have the best quality water I could possibly wish for, and at an affordable price. I am now looking forwards to reaping both the health and financial benefits of my filtration systems. I highly recommend the Waterfilterman team.

FAQs About Reverse Osmosis Water Filters
A reverse osmosis water filter in Perth removes up to 99% of dissolved solids, heavy metals, chlorine, fluoride, chemicals and microplastics from your drinking water. The multi-stage process targets contaminants that standard carbon filters cannot catch. This makes it the most thorough form of drinking water purification available for residential use. We can explain exactly what each stage removes when we provide your quote.
Most Perth reverse osmosis system installations are completed in a single visit, typically within a couple of hours. We fit the unit beneath your kitchen sink and install a dedicated filtered water tap on your benchtop. There is no major plumbing work required and we leave the area clean and tidy. You will have purified drinking water the same day.
The pre-filters and post-filters in your reverse osmosis filtration Perth system typically need replacing every 6 to 12 months, while the RO membrane lasts around 2 to 3 years depending on usage. We schedule routine servicing and contact you when replacements are due so nothing gets missed. We use industry-standard components with no proprietary lock-in. You are free to source your own or let us handle it during a service visit.
Yes, in most cases. Our Perth RO water filter systems are compact and designed to fit under standard kitchen sinks found in the majority of Perth homes. We ask you to send through a photo of your undersink space before quoting so we can confirm the best configuration for your kitchen. If space is tight, we can recommend alternative setups that still deliver the same water quality.

We can help you decide which system suits your needs and budget during the quoting process.
