System for purifying and removing contaminants from gaseous fluids

A method of enhancing purification of a gaseous fluid utilizing a system including a housing, a removable hollow cartridge disposed within the housing and including an elongated UV chamber disposed within the hollow cartridge, a UV radiation source disposed longitudinally within the UV chamber of the hollow cartridge, at least one baffle structure disposed at an upstream location within the housing, and a fan, the method comprising the steps of:

• providing electrical power to the UV radiation source to facilitate generation of UV radiation within the UV chamber;
• flowing fluid through the housing and the UV chamber via the fan;
• facilitating the generation of turbulence and mixing of fluid flowing into the UV chamber via the baffle structure;
• restricting fluid flow through the UV chamber to increase exposure time of the fluid to the UV radiation;
• and
• removing the cartridge from the housing to facilitate at least one of providing a new cartridge within the housing and replacing the UV source within the cartridge.
