Exemplary embodiments are directed to an air purifier system. The air purifier system includes a housing, a light source disposed within the housing, and an air guide positioned around the light source. The housing includes at least one intake opening and at least one outlet opening. The light source defines a light source length and is configured to emit light of a wavelength capable of killing pathogens in air passing the light source. The air guide redirects flow of air around the light source in a pathway having a length longer than the light source length.
