Which features require UV water purification?

• A. Microbe & Mould Control (UV light on cooling coils & water pan)
• B. Water Treatment
• C. Biophilia II - Quantitative (in the required water features)
• D. All of the above

Answer: (D)

UV water purification is used wherever microbial control is needed in water systems that occupants interact with. In Microbe & Mould Control, applying UV light to cooling coils and the water pan directly reduces microbial growth, suppresses mold, and prevents biofilm formation, helping maintain indoor air quality and system cleanliness. For Water Treatment, UV purification is a common step to inactivate microbes in the water supply, complementing filtration and chemical treatments to ensure safe, high-quality water. In Biophilia II - Quantitative, UV helps keep required water features clean and visually clear, supporting occupant comfort and the naturalistic water experience without relying on chemical additives. Because each of these areas relies on effective microbial control through UV disinfection, all of the above features require UV water purification.
