Germicidal UV Lamp. The most effective way to destroy micro-organisms, such as germs, viruses, fungi (such as mold) and bacteria. Also destroys micro-organisms including those that are trapped by the HEPA air filter, preventing them from reproducing and recirculating through the room. UV lamps are recommended by the U.S. Centers of Disease Control.

Ion/UV Light Indicator -
Now you can know the ionizer and UV lamp are working properly.

This sensor verifies the ionizer and UV lamp are working properly. Without these sensors, it is very difficult to know if UV lamps and ionizers are fully operational, since there are few visual or audio signs to verify this. When they are both working properly, the blue light under "Ion/UV Indicator" will go back and forth between dim and bright. The UV light and negative ion indicators let you know when the UV lamp needs to be replaced.

UV Wavelength: 254 nm (germicidal wavelength)
