A disinfection and deodorization equipment using ultraviolet light (UV-A) as energy source in the Photo-catalytic process for cleaning environments where Microbial pathogens or Volatile organic compounds are present causing HAl (Hospital Acquired Infections) or malodours are disclosed. In one embodiment, a disinfection and deodorizing equipment is disclosed which includes a Reaction Chamber having an inlet for receiving air and an outlet for discharging clean air by Photo-catalysis process which in turn accelerates the oxidization process in the atmosphere and decomposes any airborne toxic or volatile organic matter. The reaction chamber further includes a plurality of segmented baffles with various sizes, shapes and designs.
