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.

Hats off to Marlon and the team at Sentry Water Filters for their assistance with selecting the best system for my needs. Very easy process of recommendation, professional, prompt response to enquiry and delivery.
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.
