The World Health Organization recommends that silver in a colloidal state produced by electrolysis of silver electrodes in water as well as colloidal silver in water filtration for removal of bacteria are effective water disinfection methods for safe drinking water which can be adopted in developing countries.

Colloidal silver (a liquid suspension of microscopic silver particles) contains very small biological particles of silver that is so small, it can pass through membranes and even skip past the digestive system in order to be absorbed by the body specially (for maximum effectiveness) taken on an empty stomach. Colloidal silver has been ingested to treat a variety of diseases for thousands of years.

There is no debate, regarding the effectiveness of silver against bacteria and microbe infections since silver and most silver compounds have an antimicrobial effect and silver metal ions are toxic for bacteria, algae, fungi, molds, spores, and viruses even in small concentrations.

In a silver tank, drinking water can be stored for extended period of time while still rendering it safe to drink. Precisely for this reason, water tanks on board cruise ships, military ships, and airplanes are very often stored in a water tank made of metallic silver.

Electrolytic-dissolved silver has been used by the International Space Station as a water disinfecting and anti-microbial agent for the drinking water supply for astronauts Silver has natural antibiotic properties, and as a result, it has been used extensively for medicinal wound dressings to treat external infections, and additionally used as an antiseptic and disinfectant in medical appliances.

SILV Guardis a colloidal silver product that disinfects water at a rate of 30 mL to 1200+ liters of water.
SILV Clean is a silver colloidal product embedded in a near nano amino acid matrix as a suspension. It is a superior disinfectant, eliminates bad odors without masking them, and inhibits the growth of all pathogens
