"Structured Matrix" - How the Structured Matrix PURIFIES your water without using chemicals! 1) >Ultrafine Microstraining - Physically removes disease bacteria, pathogenic cysts like Giardia, Cryptosporidia, and other specific parasites and debris down to 0.1 microns (0.4 absolute). Removing the pathogens also removes the disease toxins they contain and is far more superior to "poisoning" organisms with pesticides and allowing the pathogen residue, toxins and pesticides to remain in the water to be consumed. 2) Broad Spectrum Molecular Capture - Traps and captures specific organic and other chemicals such as pesticides, herbicides and solvents, as well as chlorine and other trace contaminates that can be toxic and/or carcinogenic, along with foul taste, odour and colour. 3) Electrostatic Removal - Uses specially charge space-aged surfaces, essentially as magnets to remove minute particles, molecules and colloids suspended in the water. All of these purification mechanisms work together to REMOVE viruses, disease bacteria and other contaminants far smaller than submicron microfiltration alone can remove.
