Firewall™ Technology is at the heart of the Waterlogic WL-350™ Tower treatment process. Firewall™ Technology with ultraviolet light purifies the water to 99.9999% bacteria free. It acts as a final barrier to pathogens right at the point of dispensing. The design allows for higher UV exposure which reduces bacteria, viruses and parasites that may be in the water, purifying the water up to 99.9999% of any bacteria 100% of the time.
Point of dispense purification keeps the dispense nozzle free from external contamination as well as purifying the water as it fills your cup, making the freshest water possible. The Firewall™ technology has been tested and certified by the Water Quality Association to NSF/ANSI-55 Class A UV and NSF/P231 US EPA standard for microbiological water.
