The first step of the filtration process works with what is referred to as size exclusion. At this stage, all particles bigger than 0.4 micrometer as well as most bacteria are filtered out by a ceramic membrane block filter. This ceramic membrane block candle forms the core of every Nazava water filter.
Active bacteria removal
In a second step, the bacteria trapped in the ceramic membrane candle is eliminated by nano-silver. Nano-silver has been widely used in medical treatments for more than 100 years and has proven to be a powerful anti-microbial agent. By attaching to bacteria and fungus, positively charged silver ions (Ag+) disrupt the cell metabolism and hinder cell growth. Cell multiplication is inhibited by the nano-silver by suppressing the bacteria’s basic functions like membrane permeability and the cell respiratory system.
Improved odour and taste
The last step includes the absorption of chemicals and organics by ultra-high-grade activated carbon to improve odour and taste.
