The Metropolis Silver Nano Ionic Paddle Brush purifies and removes odors from the hair. Silver Nano Technology is a recently discovered process that uses nanotechnology to micronize particles of silver. This makes it now possible to reap the scientifically recognized benefits of silver. For centuries silver (Ag) has been revered for its amazing therapeutic properties and effectiveness. The nano silver eliminates 99% of bacteria, fungi and hundreds of other disease causing microorganisms by inhibiting multiplication and growth and preventing transfer. Having these silver ions of nano size emitting from the bristles in a colorless anti-bacteria armor, Metropolis brushes are able to benefit from the safe and sanitizing power of the sophisticated silver nanotechnology. Bacteria are blocked from contaminating and "odorizing", providing a safer and cleaner environment in the home or workplace.
