Filter 1: KDF and Granulated Activated Carbon.
The KDF will filter out heavy metals, chemicals including chlorine, and other toxins and extend the life of the carbon. The carbon will improve taste colour and odour of the water.
Filter 2: Carbon Block
Will filter out solid dirt particles down to 5 micron and provide extra carbon to allow for higher flow rates.
Filter 3: ultra filter
Ultra Filters are membranes which filter down to 0.2 micron which will mean that it will filter out very fine contaminants including bacteria.
