Frequently asked questionsCategories All About Bluewater Cleone PRO Spirit Water purification & TDS Bluewater Spirit How long will my Bluewater Spirit last? The Bluewater Spirit has been engineered to deliver cleaner, healthier water that you can trust for drinking and washing fruit and vegetables for a great many years. Is it difficult to change a filter? Changing a filter in a Bluewater Spirit has been designed to be as easy as possible. The Spirit manual explains the simple steps required to change a filter or, alternatively, look at our filter change video, which will talk you through the process. How often do I need to change a filter? The frequency of filter change depends naturally on the quality of the water being purified by your Bluewater Spirit. We generally advise filters should be changed at least every six months. However, the Bluewater Spirit is equipped with a ‘water quality monitor’ to supervise the quality of feed and filtered water – should the water deteriorate, a lamp will light up to advise you a filter change is required. What exactly is SuperiorOsmosis™ technology? Innovated in Sweden, SuperiorOsmosis™ delivers such benefits as superior purification efficiency, operating capacity and service life. Slashing the water waste traditionally associated with reverse osmosis systems by up to 79% with a recovery of 61%, the Bluewater Spirit’s SuperiorOsmosis™ technology removes the need for a tank to deliver direct flowing water and can deliver a stunning 3380 liters per day. Does the Bluewater Spirit purify all kinds of water? Bluewater Spirit is designed to purify water being delivered from a municipal water utility. It harnesses Bluewater’s unique second-generation SuperiorOsmosis™ technology to remove impurities and contaminants that may be found in municipal water.
