The use of 2x carbon block filters is increasing due to the chemical treatment in municipal water supplies. The introduction of chloramine gas injection sanitation has lead to some unforseen complications both in terms of health impacts and also water filtration. Dual carbon filters are now necessary to break open the chloromine and once open, remove it from the water. The use of 2 carbon filters gives the water 2x the contact time with carbon, thus increasing the effectiveness of removing chemicals from the water, in particular chloramine. For a more detailed explanation about this new water treatment method you can follow the link below.

5 micron Pure Carbon Block Cartridge:

This high quality 100% Coconut Carbon filter is the exact filter we use as our frontline carbon filter. As a rule it is difficult to find 100% coconut carbon filters. Most lower priced filters on the market are a blend of coconut carbon and coal based carbon. The problem with coal based carbon is that it has a shorter life and often results in a less palatable flavour. We use this 100% coconut carbon filter in all of our pre-assembled kits.

These are top of the range HIGH QUALITY coconut carbon block filters are ideal for taste and odour issues, and perfect for total extraction of town water chemicals. TOP OF THE RANGE 100% coconut carbon, this particular filter is currently supplied throughout the European market as a premium drinking water filter. As the Exclusive importer to Australia, we are in a prime position to offer you this high quality filter at rock bottom prices, direct from importer to the public.

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be sweetest tasting water. The unique pore structure of this carbon is well suited for chemical absorption, including VOC's, while reducing chlorine and chemicals that contribute to taste and odour.

Contains Poly Prophylene ends and meshing rather than rubber. (Rubber has a tendancy to harbor bacteria). Poly Prophylene is designed with this in mind, resulting in long life and pure water. NO BAD SMELLS OR TASTES. This filter is truely as good as it gets!

These filters are a terrific opportunity to purchase extremely high quality filters at a VERY low price. They are best suited for gravity fed tank water supplies, or town water. 

Carbon filtration is the best form of filtration for chemical extraction due to the longer and more thorough contact time the water has with the carbon, which in turn provides an extremely comprehensive method of chemical removal. We HIGHLY recommend this method of filtration for chemical taste and odour extraction.
