First Water purification systems combine advanced filtration and disinfection technologies to produce microbiologically safe drinking water from a wide range of compromised freshwater sources. Whether drawing water through an integrated pump or utilizing an existing pressurized supply, every system employs a multi-stage treatment process designed to deliver reliable performance in the most demanding environments.

Our purification process includes multiple layers of treatment, each engineered to remove specific contaminants:

• Sediment Filtration removes dirt, sand, rust, and suspended debris.

• Activated Carbon Filtration improves water quality by reducing taste, odor, chlorine, and organic compounds.

• Proprietary Zeonic® Virus Filtration removes viruses, bacteria, cysts, and other harmful microorganisms.

• Class A Ultraviolet (UV) Disinfection provides redundant microbiological protection by inactivating any remaining organisms.

At the core of every First Water system is our proprietary Zeonic® filtration technology, derived from innovations originally developed through NASA-supported research. This advanced filtration media achieves exceptional removal of microbiological contaminants while maintaining high water production rates. Following mechanical filtration, water passes through a Class A ultraviolet disinfection chamber, providing an additional layer of protection and redundancy to ensure consistently safe drinking water.

First Water’s treatment system has been independently tested per NSF Protocols P231 and P248, the protocols for microbiological water purifiers used in civilian emergency response and military operations. Both are derived from the U.S. EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers, and P248 was developed with the U.S. Army Public Health Command. In independent laboratory challenge testing, the system met the P231/P248 pass criteria for bacteria, viruses and Cryptosporidium oocysts in both general and challenge test waters. The full laboratory reports are available on our Resources page.

The same proven purification technology is incorporated throughout the First Water product family. Each system is built on a purpose-designed chassis engineered for its intended application, whether portable field deployment, mobile emergency response, or permanent facility installation. Filtration components are then scaled to match the required flow rate and operational capacity, ensuring dependable performance across every product in the First Water lineup.
