Disclosed is a chemical and biological air purifier. The air purifier has a housing having an inlet and an outlet both aligned on a longitudinal axis, a turbulence generator, one or more vacuum ultraviolet (UV) sources achieving a chemical purification and one or more germicidal ultraviolet (UV) sources achieving the biological purification. The turbulence generator is mounted within the housing downstream of the inlet and promotes a dispersion and mixing of air received through the inlet. The vacuum UV source is mounted within the housing downstream of the turbulence generator and breaks oxygen molecules into mono-atomic oxygen which then reacts with chemical contaminants present in the air and degrades them by successive oxidation to odorless and inoffensive byproducts. The turbulence generator reduces the production of ozone by increasing the contact between the mono-atomic oxygen and the chemical contaminants. The germicidal UV-C source is mounted within the housing parallel to the longitudinal axis of the housing downstream of the vacuum UV source. The germicidal UV-C source, in use, kills biological contaminants present in the air by irradiation and degrades residual ozone produced by the vacuum UV sources into molecular oxygen, thereby purifying air from the biological contaminants and residual ozone.
