The H1-46CRC is the pinnacle of filtration system when it comes to mains water filtration under the sink for drinking water. The advanced technology cartridges ensure that hazardous chemicals such as Chlorine and Chloramine are removed from your drinking water, along with a monumental amount of other VOC’s and DBP’s (By-products of Chlorination. Chloramine is fast becoming the most important topic when it comes to municipal mains water. Free chlorine has long been the choice of water companies and councils until the use of Monochloramine has yielded significant improvements to expenditure for water sanitation. Unfortunately for the consumer, chloramine poses several health and aesthetic effects from skin & Respiratory issues to heavy metal leaching (from old pluming). Aesthetically monochloramine gives a strong Chemical Smell in the water and when mixed with the fluoride additive in water can also increase the corrosiveness and has been known to dissolve copper and lead from plumbing. A primary 20uM Low Pressure Carbon Block (LPD 2510-20) removes all traces of VOC’s and free Chlorine while maintaining good water pressure & Flow rate, followed by the 0.5uM Catalytic Chloramine Removal Carbon (CRC 2510-P5) that denatures and neutralises the Monochloramine molecule, breaking it down to simple elements such as water, hydrogen, nitrogen and a small amount of chlorine which is absorbed during the final contact with the carbon.
