Zero-carbon Manufacturing

Our ceramic filtration units are environmentally friendly and benefit from an exceptionally low carbon footprint. Our factory is powered entirely by green energy, making use of our own solar farm and wind turbine. We constantly strive to make our manufacturing techniques as energy efficient as possible.

Scientific Testing & Verification

To ensure our products meet the highest standards, stringent testing and quality control procedures are followed throughout the manufacturing process.

Performance is regularly tested and verified to the applicable standards for point-of-use drinking water filters and purifiers by an independent, third-party test laboratory, where effluent water is tested to guarantee that all contaminants have been removed.

For a detailed breakdown of our testing procedures, please see our performance data sheets for the Sentry ceramic water filter, CTO Plus ceramic water filter and the Max ceramic water filter.
