Instructions for re-filling silver carbon filter:
1/ Remove the filter from its mounted position.
2/ Screw off the end cap and tip out the old carbon.
3/ Rinse then soak the housing and cap in a mild sanitiser for an adequate period of time.
4/ Rinse well, then pour in the new carbon, being sure to remove any loose carbon from around the cap.
5/ Re-install the filter ready for use.
So, how does Silver Impregnation inhibit the growth of bacteria in a carbon filter? When bacteria come into contact with silver, the silver ions puncture the bacteria's cell membrane and wreak havoc by binding to and denaturing the bacteria's DNA. The sulphydryl group already within the bacterial cell also reacts with the silver, producing a silver sulphur complex that immobilises the respiratory and reproductive activity of the bacterial cell. Interestingly, Silver Impregnation has an incredibly long-lasting effect, as the dead bacteria then leach the silver molecules back into their environment, effectively killing neighbouring live bacteria as they die.
Dead bacteria store the microscopic silver particles within their cells (see above image of dead bacteria with silver nanoparticles (white spots), making them deadly to live bacteria. (Source: "Antibacterial Activity of Silver-Killed Bacteria: The "Zombie" Effect" (2015), https://pubmed.ncbi.nlm.nih.gov/25906433/).
For sanitation against common water-borne bacteria/viruses in rainwater and potable bore water (i.e. *bore water that has been tested to the Australian Drinking Water Guidelines and deemed suitable for drinking purposes per the Guidelines’ aesthetic, health and safety recommendations), we recommend dosing your water source with a product such as Hydrosil Ultra 7.5% Water Sanitiser. Dosing with a disinfectant will ensure residual protection against microbiological contamination/biofouling in your pipework and/or filter system. Alternatively, for a full-time point-of-use sanitation solution, consider Ultraviolet (UV) Water Sanitation.
