Light is an amazing source of energy. It is the power behind virtually everything that happens on Earth. Light from the Sun brightens the dark depths of space, makes plants leap to life, and powers our bodies. But did you know it can help to clean things as well?
In air purifiers that work using a method called photocatalysis, light energy kick starts a process that destroys all kinds of nasty air pollutants and turns them into harmless substances instead. Light-powered LumeeLamps are effective devices in the fight for cleaner air and better health.
