Abstract
A portable or handhold air cleaning system, whose air flow pipeline made of highly reflective and low absorptive material for UVC or UVB light acts also as a UV light waveguide, is invented. The system features a TEC cooled LED light source; air flow warm up mechanism; and UV light absorption/air cleaning enhancement device. The system is useful for travellers and office workers during flu and hay-fever seasons.
