    5 Stages of filtration


    1. The first stage of the filtration process is a 10-inch sediment filter. This filter is made from 100% pure polypropylene and has an extra high capacity. This pre-filter will remove and reduce sediments, including rust, dirt, silt and sand.

    2. The second stage of the filtration process is a 10-inch GAC filter. This filter is made from high performance activated carbon. The second pre-filter will remove and reduce chlorine, odour, organic contaminants, pesticides and chemicals.

    3. The third stage is a 10-inch carbon block filter which is made from high-performance carbon. This final pre-filter will remove any remaining chlorine and other volatile organic contaminants and 99.95% of giardia and cryptosporidium cysts.

    4. Once the pre-filtration stages have taken place your water will pass through the 50 GPD Reverse Osmosis membrane where the main filtration will take place. This will reduce and remove between 97 – 99% of contaminants.

    5. The fifth and final stage is an inline carbon taste and odour filter.  This will improve the taste and odour of your drinking water.  This high-quality system is expertly manufactured using water safe products.

    All our reverse osmosis water filtration systems come fully tested, with filters and membranes installed.  The system will be ready for use with all the necessary components as well as an installation guide.

    The system includes filters and membranes as well as a storage tank. We recommend replacing the filters every 6-12 months to ensure uninterrupted, high quality, pure water.
