▎ 摘　　要

NOVELTY - The system comprises one high efficiency particulate air filtration unit (HEPA filtration unit) (102). First HEPA filter bed extracts air from external atmosphere and performs a HEPA filtration. One disinfection unit (104) is coupled to HEPA filtration unit and provides multiple ultraviolet (UV) lamps (306A-N) which is arranged in a criss cross arrangement. First pollutant removal unit (106) is coupled to disinfection unit and is used to remove harmful gaseous pollutants from the disinfected air and for releasing purified air to an indoor environment. Pollutant removal unit provides one graphene-material based active bed for filtering harmful gaseous pollutants. USE - Air-purification system for ultraviolet light-based air purifier. ADVANTAGE - Air purification system eliminates pollutants and microorganisms and provides a comprehensive air purification efficiently. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of air purification. DESCRIPTION OF DRAWING(S) - The drawing shows an isometric view of an ultra-violet radiation-based air-purifier system.
