4N1 Gradual Sediment Filtration

Multi-Sectional Filtration for Pure Protection, Down to 1-Micron 

Our 1-micron 4N1 Sediment Filter is no ordinary filter. By engineering four sequential pore gradients linked through a proprietary density transition process, we have eliminated the pressure drop and filter life inconsistencies common in all conventional single and dual‑layer filters to best protect a home’s water and the people who rely on it. 

To ensure the best filtration performance, we have specifically chosen based on research and testing, four precise gradient filtration zones that water flows radially through. Our advanced four stage graduated filtration not only clears out ultra-fine municipal particles but also tank-based treatment carbon fines when used as a polish filter.

The proprietary 1-micron 4N1 Sediment Filter will reduce parasites and cysts that may be present in a water supply, when the more porous standard sediment filters do not. We do this with a relatively longer-lasting filter while maintaining a strong water flow. Helping keep your customers’ appliances, filtration and family, happy and healthy. 

Proven Performance Where It Matters Most - Our Children’s Schools 

In real-world testing across hundreds of public schools, our 1-micron 4N1 Sediment Filters delivered healthier, cleaner water while lasting significantly longer than the industry-standard 5-micron sediment filters.  

Typically, schools using 5-micron filters required service visits every 2-3 months. But in schools equipped with our 1-micron 4N1 filters, systems ran smoothly all year- right up to the recommended annual filter change. That’s 4-6 times longer-lasting protection, thanks to our proprietary design. 

Each system using a 1-micron 4N1 filter saved the water treatment company hundreds of dollars in service costs every year. The extended filter life did not just reduce company costs; it also provided a happier, more satisfying customer experience for improved peace of mind.
