Feature X08 requires projects to implement air treatment systems that reduce the concentration of contaminants in the air. Ultraviolet air treatment is one of the options that can be used to meet this feature.
However, the project must also provide evidence that the required components of the UV system, such as lamps, ballasts, and filters, have been replaced or maintained according to the manufacturer's recommendation. This ensures that the UV system is functioning properly and effectively. The other options are not directly related to the UV system maintenance and inspection.
