NanoPak Biological Electropositive Filter
The NanoPak Biological Electropositive Filter delivers advanced, sustainable water purification using Ahlstrom Disruptor® electropositive media—a technology originally developed for NASA’s space program. Designed for residential, commercial, and emergency water treatment, NanoPak combines powerful microbiological protection with high flow rates and easy maintenance.

Unmatched Microbiological Protection
99.9999% (6-log) bacteria reduction
99.99% (4-log) virus reduction
99.9% (3-log) cyst reduction
Independently tested to exceed EPA microbiological purifier standards.
Broad Contaminant Reduction
Removes heavy metals such as lead.
Reduces chlorine, PFAS (“forever chemicals”), VOCs, and other chemical pollutants when paired with carbon filtration.
Electroadsorption Technology
Uses electropositive charge to capture submicron contaminants that pass through ordinary filters.
Eco-Friendly Design
No chemicals, no electricity, and zero wastewater.
Preserves beneficial minerals in your water.
High Flow, Low Pressure Drop
Performs even in gravity-fed or low-pressure systems.
