Whirlpool Wpro Inline Water Filter Cartridge for Use with Side By Side American Style Refrigerators 484000008553

This Wpro Inline water filter purifies the tap water coming from your Side by Side dispenser to reduce the taste of chlorine, sediment, dirt, rust and odours, providing better tasting water and ice. It protects your ice maker and water valve?s life to deliver you the best performance from your Side by Side refrigerator. It is designed to filter 1500 litres of water, lasting 6 months, in addition to including quick fittings and connectors, making it is easy to install. What is contained in the tap water in the UK? Tap water is treated with a large number of chemicals in order to kill bacteria and other microorganisms. In addition, it may contain other undesirable contaminants like toxic metal salts, hormones and pesticides, or it may become contaminated by chemicals or microbes within pipes (e.g. lead, bacteria, protozoa). Knowing that, it is important to filter the tap water properly. Activated carbon filters remove or reduce many volatile organic chemicals (VOC), pesticides and herbicides, as well as benzene, chlorine (including cancer-causing by-product trihalomethanes), radon, solvents and hundreds of other man-made chemicals found in tap water. Activated carbon filters are usually rated by the size of the particles they are able to remove, measured in microns, and generally range from 50 microns (least effective) down to 0.5 microns (most effective). How does the filter work? What is inside the filter: Carbon is the primary substance used in the water filter because activated carbon has the potential to adsorb many of the chemicals found in water. The most common carbon types used in water filtration are bituminous, wood and coconut shell carbons. How it Works There are two principal mechanisms by which activated carbon remove contaminants from water: adsorption and catalytic reduction. Adsorption: involves the accumulation of molecules on the surface of the activated carbon (organic compounds). Catalytic reduction: involves the attraction of negatively-charged contaminant ions to the positively-charged activated carbon (residual disinfectants such as chlorine). These tiny holes allow liquids or gases to pass through the charcoal and interact with the exposed carbon. Because adsorption works by chemically binding the impurities to the carbon, the active sites in the charcoal eventually become filled. Activated charcoal filters become less effective with use and have to be replaced. What are the main advantages of Filtered water vs. Bottled water ? Always having freshly filtered cold water and ice Space saving over bottled water No waste from plastic bottles Avoiding allergies and knowing what type of contaminants your water filter removes Why is it important to change the filter every 6 months? The two most important factors affecting the efficiency of activated carbon filtration are the amount of carbon in the unit and the amount of time the contaminant spends in contact with it. Particle size also affects removal rates. Thus, filtration
