Our locally assembled reverse osmosis units are designed to provide the purest possible drinking water at a reasonable price. All of our locally assembled units are leak tested overnight under pressure and checked to ensure that they are operating optimally and producing water of a standard that meets our quality guidelines.

Reverse osmosis technology is known for its ability to produce pure water of a consistent quality, typically reducing the total contaminant in the feed water by +/- 96% on average. Our systems are effective in removing / reducing various contaminants from your drinking water, including fluoride, chlorine, cysts, bacteria and heavy metals among many other contaminants as indicated in the table below.

Exceptional Service and Quality Product

I am extremely pleased with both the product and the communication process with the owner, Marlon. Marlon was exceptionally helpful and patient in responding to all my product-related inquiries and provided thoughtful recommendations tailored to my specific needs. He also kindly recommended local plumbers in the Sunshine Coast area with extensive experience installing water filter systems. This was such a relief, as it removed the burden of having to search for a qualified plumber myself.

In terms of the product, I purchased the 8-litre system, which fits perfectly in my under-sink space. I believe this size is well-suited for 1–2 people. The water pressure is reasonably strong and has been entirely satisfactory for my personal use.

So Min,
Thank you for your kind words and for taking the time to share your experience with our Under Sink Reverse Osmosis RON 4 + 5 Stage Membrane Filter. We are happy to hear that our product and customer service met your expectations. We value your feedback and are glad that our owner, Marlon, was able to provide you with excellent service and helpful recommendations. We hope that our product continues to meet your needs and we appreciate your support. Cheers!
