The Health Factory First Aid Silver Spray / Nano Silver 15ml Spray
The small size of the silver particles is important because smaller particles provide a greater surface area per volume which in turn allows the silver to exert a greater effect.
The particles are typically 0.01 to 0.001 of a micron in diameter (about four hundred thousandths to four millionths of an inch), with a positive electrical charge place on each silver particle.
Ingredients: 100% nanosilver particles, and nothing else. How to use? Purified water with 15mg / l (15ppm) ultra-fine particles of pure, 99.99 non-compound silver.
