Reverse Osmosis Water Filter Cartridge Replacement Kit Replacing other makes of Reverse Osmosis If you have more than 2 Housing Chambers Installing your new Cartridges Replacing the Filters in the Future Changing Revese Osmosis Membranes But do you really need the fuss of Reverse Osmosis? If you bought your reverse osmosis system from us then you can Order a New Membrane Now Replacing Other Makes of Reverse Osmosis If you already have a Reverse Osmosis type water filter - that is a water filter with two or more housing units lying beneath a main system - see pictures - and you cannot replace your filters with your usual supplier we might be able to help We probably won't sell the original cartridges but we might be able to supply you with high quality, compatible cartridges. Firstly almost all reverse osmosis water filters on the market are basically the same. Anyone can buy a generic reverse osmosis unit from a factory in China and stick on a glossy looking label with their "brand name". Unfortunately many people who do this and then sell the filter to unsuspecting customers at a vastly over inflated price of £400 plus, often tend not to worry too much about the simple matter of supplying the required replacement filters. The problem is that you usually need to change your cartridges every 6 months to ensure your water filter operates properly. The good news is that most water filter cartridges are basically plastic tubes filled with carbon. This carbon is simply burnt coconut shell. Changing one make of cartridge for another is not unlike changing one light bulb for another. They all do the same job. It is simply a question of getting the size right. Our reverse osmosis replacement kits comprises 2 high quality 10 inch 5 micron type carbon block pre filters plus a post filter. One of the original filters you probably have is a lower quality sediment type filter. Please rest assured that our better one does the same job but much more effectively. More than 2 housing chambers? If you have three or more "lower housing chambers" under your main RO unit then you can leave the surplus ones empty. It is simply not necessary to have them all occupied. Our 2 high quality ones will suffice. (It seems that some RO manufacturers simply fit more than 2 housings in order to increase their renewal income). Place our cartridges in the chambers nearest the RO filter. (ie leave the chambers nearest to the water supply empty). This means the empty chambers will be kept "sterilised" by the chlorine in normal mains water To make sure our cartridges will fit you simply need to measure the filters that are in the lower housing chambers and make sure they are - like ours ie: They are 9 and 3/4 inches (250mm) high Their diameter is approx 66mm. They have a 1 inch hole at either end, in the middle, to slot into the housing unit. Installing The New cartridges Everything you need is in the pack. The filters are very easy to install. No plumber is necessary. Replacing will take a few minutes at most. But if you need our help, no problem; we've got friendly (and free) customer support span available. Replacing the filters in the future Like all water filters, you will need to replace the filters on the system periodically to ensure maximum performance. You need to change the three filters every 6 months. We send you a reminder. Changing Reverse Osmosis membranes Every 3 years or so you will need to change the membrane. You will know when to do this by the change in the taste of the water. The current cost of a new membrane is £79. If you need to change your membrane the best thing to do is to remove it from its housing, take a photo of it with your mobile phone and email it to us. We will be able to see if we can replace it.
