Carbon water filters remove chlorine + other chemicals
Carbon Block filters - How they work
Carbon filters remove harmful chemicals from your water by absorbing them into the filter. The slower you run water through a carbon filter, the more efficiently it will remove the chemicals. Carbon Block filters are made from Granular Activated Carbon (GAC) and formed into a solid block filter. This brilliant design gives them over 14 times more internal surface area (within the matrix of pores), than normal granular GAC filters, to absorb harmful chemicals. They also do not suffer from water channelling which reduces the efficiency of traditional loose-fill granular GAC filters.

What does a Carbon Block filter remove? Full list here: See what System 1 Filters remove (click the BACK button to return to this spot)
The filter can remove Chlorine plus Herbicides, Pesticides, Trihalomethanes, Chloroform, Benzene, Hydrogen Sulphide (odour), Discolouration, Sand, Silt, Rust and other particulates plus many other chemicals found in your drinking water, leaving it crystal clear and fresh - like mineral water. The filter does not remove the essential minerals that are necessary for good health and good flavour.

Why remove Chlorine?
A growing body of researchers worldwide have stated that Chlorine in our drinking water is a cause of Cancer in many forms. Chlorine is also reported to be a serious cause of Miscarriage / Stillbirth and many other serious medical problems. more >>
