Carbon is a natural substance, known for its amazing property of extracting/removing/reducing impurities and contamination either organic or inorganic. Carbon is probably the most powerful absorbing agent discovered by man. A less than half kilogram carbon has a surface area of approximately 125 acres and capable of absorbing thousands of different contamination present in water.
The most common carbon types used in water filtration are black coal, wood, and coconut shell carbons. Though coconut shell carbon typically costs 20% more than the others, it is generally regarded as the most effective of the three. All of our activated carbon filters use coconut shell carbon.A normal counter-top or under-the-counter filter system has from 0.34 to 0. 68 kilogram of activated carbon.
Carbon filters are intended to remove chlorine, chloramine, chlorine disinfection by-products (trihalomethanes – THMs), general bad tastes & odors, volatile organic compounds, and a broad range of other common water contaminants to ensure the best water possible for usage.
Granular activated carbon and carbon block pre-filters both are active carbon -being called activated because it has positive charged ions added to it and capable to extract negative charged ions from water such as ozone, chlorine, fluorides and dissolved organic solute when water is passed through it.
Activated carbon filters size and contamination removal rate is measured in microns, generally range from 50 microns down (lowest efficiency) to 0.5 microns (maximum efficiency).
