A UV light must strike the contaminants directly in order to penetrate the microorganism and render them ineffective. The reflective coating within each Sonicare sanitizer distributes UV light around the top of the brush head and right down to the bristles, making sure to touch the entire brush head surface and offending germs.
The Philips Sonicare UV sanitizers use a small, special UVC generating lamp. UVC is a proven sanitization and purification technology. The range of light classified as UVC is called the germicidal bandwidth. Germicidal UV has been used safely and effectively in hospitals, clinics and laboratories for more than 60 years to sterilize surgical instruments, water, and the air in operating rooms. Many food and drug companies also use germicidal lamps to disinfect various types of product containers.
Ultra violet (UV) light is generated by the sun. It is naturally occurring, and is part of the light spectrum. The full spectrum includes radio waves, infrared, visible light, ultraviolet, x-rays, gamma rays and cosmic rays. Most other sources of light, such as light bulbs, also generate some UV light.
UVC light is a proven technology currently used in a variety of purification and sanitizing applications. Direct and prolonged exposure to UVC causes temporary skin redness and eye irritation. However, our products are designed to shut off when the door is open, thus eliminating any direct exposure. The electric power should always be turned off when replacing or cleaning the UV lamp in your Philips Sonicare unit.
