    Advanced Bronze RO Replacement Filter Set

    The Bronze RO advanced replacement filter set has two main advantages over the standard Bronze Replacement Filter Set:

    • The first stage filter is a 1-Micron Anti-bacterial Melted Spray cartridge, rather than the normal 5-micron Melted Spray cartridge. This filter will filter finer than the 5-micron cartridge, but more importantly, the Anti-Bacterial Melted Spray cartridges have a bacteriostatic function which helps to inhibit the growth of bacteria on the surface of the filter, helping to ensure healthier product water and a longer life span of the filter. 


    • The Activated Carbon Filters in this set (GAC, CTO, & T33) all have an iodine rating of 1000mg/g, the standard filter set's carbon filters only have an iodine rating of 300mg/g. Essentially what this means is that these carbon filters are 3 times more effective at absorbing chlorine and organic molecules from the water at the same flow rate. This means greater protection of the RO membrane against potential damage due to chlorine getting through from the pre-filters. 


    Filter Description:

    Stage 1: 1um (Micron) Anti-Bacterial Sediment Filter:
    This removes particles from the water down to 1 micron, the anti-bacterial cartridge also inhibits the growth of organisms on its surface giving it a longer life span.

    Stage 2: Premium Coconut Granular Activated Carbon (GAC) Filter (Iodine Rating - 1000mg/g):
    This filter contains granular activated carbon, which absorbs chlorine and organic molecules, reducing bad odors. 

    Stage 3: Premium Activated Carbon Block Filter (Iodine Rating - 1000mg/g):
    This filter contains an activated carbon block, which absorbs chlorine and organic molecules, reducing bad odors. It also includes a 5um (micron) filter to catch any carbon particles which may break off during filtration.

    Stage 4: RO Membrane (Optional)
    Removes Bacteria, Viruses, Heavy Metals, Pesticides, Herbicides, and Reduces the Mineral Content (TDS) by up to 96%. This filter has a life span of 2-3 years. This is an optional extra.

    Stage 5: Coconut T33 / post Filter (1000mg/g) 
    Removes any smells or tastes left in the filtered water. It will also absorb the preservatives found in the RO membrane after new installs.


    How To Install The Filters


    Flushing the system:

    This is done by running water through the system until the preservative cannot be detected in a sample glass of water. The preservative leaves a film on the water and also has a bitter taste. If you are seeing this in your water after a new installation, flush and test until no hints of the preservative can be detected. Please note if there is a white color to the water that settles out towards the top of the glass, this is most likely caused by tiny air bubbles in the water. This should subside over time as excess air in the system is removed. The air bubbles in the water will not affect the quality of your drinking water.

    How to remove/replace your filter:

    Start by unscrewing the filter housing from the filtration unit. This is done by rotating the filter housing in a clockwise direction (see diagram below). The filter housing will separate from the filtration unit, and you are now free to remove the filter cartridge from the filter housing. To replace your filter: insert the new filter into the filter housing. Be sure to remove any protective plastic wrapping from the filter cartridge before placing them into the filter housing. Check that the black rubber O-rings are in place and fit well on the filter housing. If they seem perished or loose you may want to purchase new O-rings to ensure a good seal. As an option you can add a little bit of Vaseline on the O-rings to make them seal better, this will make it easier to open next time. Take note of the single rubber seal on one side of the Granular Activated Carbon Filter (GAC). This will need to face upwards to connect and seal at the top of the filter housing. It is important that this is done correctly as the system will not work optimally if the filters are installed incorrectly. Now that your filter is in the housing, bring the housing to the filtration unit and begin to screw the two together. This is done by rotating the filter housing in an anti-clockwise direction. We recommend you tighten by hand as this is usually sufficient to maintain a good seal. If however, leaks are detected, the housing spanner can be used to tighten the filter housings until a good seal is achieved. (Check O-rings are correctly in position before tightening with the spanner) Please take care not to over-tighten the filter housings. This could strip the housing thread and cause your system to fail. It will also make it more difficult to replace filters in the future if they are over-tightened.


    How to Change the T33 Cartridge:

    With these cartridges you will have one of two connectors used; the Jaco Connectors, which unscrew, much like your standard hose pipe fittings. And the Quick Connectors, use a small blue safety clip to keep the pipe in place. The cartridge connector may vary from time to time due to product availability at different suppliers. So you may find yourself with a cartridge that has different connectors to your current setup. Do not fret, they are both compatible with the flex-hose used on the RO Systems. If you have a different connector on your new cartridge, you may remove the old connector from the old cartridge, and fit them to the new cartridge. This is a simple process of unscrewing the old connector and screwing it onto the new cartridge. Thread Sealing tape is a must when refitting connectors. This tape is available at most hardware stores. Once you have your desired connectors installed you can now assemble the system. With Jaco fittings the “Nut” is placed over the hose, the hose is inserted into the connector, then the “nut” is pulled towards the connector over the hose and screwed tightly. With the quick connectors, the blue clip is removed to allow the hose to be inserted or removed. Once the clip is off, you can push the hose into the connector. You should feel the hose slide in slightly at first, this is only halfway, more pressure must be applied to the hose to nest it fully in the connector. Once the hose is pushed into the connector tightly, the blue safety clip can be replaced. Please take note of the blue safety clips' position on the connector. It must sit behind the movable part of the connector. This will secure your hose. If you have trouble fitting the hose into the connectors, this could be caused by previous connectors having damaged the hose. Simply cut the hose so that the end does not display any signs of use. This should aid in installation.


    When to change your filters:

    Filter life span is determined by the quality of the source water that runs through them. So if your source water is of very bad quality, your filters will be doing more “work” to clean the water that is flowing through them. Thus depleting sooner than filters running under good water conditions. So in short each end-users filter requirements will be different as their source waters are different. We advise you to check your filters on a monthly basis after the initial installation to get a feel for the quality of the water in your area. You will see for example, that the stage 1 filter (1um Sediment) is turning brown from the outside towards the center over a period of 12 months. If this is the case your water quality is exceptionally good as these filters generally only have a life span of 4 - 12 months filtering average South African water. If your water quality is very poor you may be replacing the 1um sediment filter every 2 months. So visual inspection of your filters is the best way to determine when to change your filters. For the Carbon filters, the “symptoms” are a little different. These filters are depleted once bacteria have colonized them completely. So in testing, you will want to see if any traces of bacteria can be detected. This is done by physically inspecting the filter cartridges. You want to check for a “slime” on the filters. This is a slippery substance and will feel similar to a mucus of sorts. If this is present on your filter cartridge then bacteria have colonized the filter and a replacement cartridge is required. 


    Adding a Housing Spanner

    Over time the housing can become tight, and difficult to open by hand. If you do not already have one available to open the housing, we would recommend adding a housing spanner. 

    The Housing Spanner will allow you to gain more "purchases" on the housing, allowing you to open it more easily.
