How ElectroPure™

Water Purification Technology Works:

Imagine a revolutionary approach to water purification that goes beyond traditional methods. Enter ElectroPure™, a game-changing technology that sets new standards in the industry. Here’s how it works:

Electroadsorptive Innovation:

ElectroPure™ is not your typical water purification media. Unlike mechanical filter media, it operates on the principle of electroadsorption. This means it doesn’t just mechanically filter out contaminants; it actively attracts and captures them.

The Power of Positive Charge:

At the heart of ElectroPure™ is its unique crystal structure, which naturally generates a robust positive charge. This charge acts as a magnetic force field, drawing in submicron contaminants that carry a negative charge.

Microscopic Precision:

ElectroPure™ features an electro-positive wet-laid nonwoven design with pores measuring just 1.2 – 1.5 microns. This level of precision allows it to capture even the tiniest particles and pathogens, mechanically removing larger particles along the way.

pH-Responsive Enhancement:

When exposed to water within a pH range of 5 – 9, ElectroPure™ comes to life. It taps into the natural crystal structure of its fibers to generate a charge potential that extends deep into the fiber pore structure, enhancing its purification capabilities.

Structured, Energized Water On-The-Go:

The Vortexer by Greenfield Water Solutions is an indispensable tool for RV enthusiasts, harnessing the power of structured water to elevate your on-the-road water experience. Structured water isn’t just a chemical compound; it embodies the essence of life, reflecting its surroundings and retaining a record of the energies it encounters. Through a meticulous process that mimics nature’s principles, the Vortexer restructures water, allowing it to maintain its natural balance and purity, free from excessive contaminants.

The Vortexer incorporates a harmonizing chamber with proprietary technology for broadband energization. It creates a toroidal vortex, mirroring the natural movements and formations found in pristine water sources. This process revitalizes and restructures the water at a fundamental level, ensuring that every drop you use enhances your RV journey.

Greenfield Water Solutions has conducted extensive global trials over the course of a decade, consistently showcasing the remarkable benefits of structured water. Whether you’re on the road, exploring remote landscapes, or setting up camp in scenic spots, the Vortexer contributes to the creation of a harmonious and revitalizing water ecosystem, ensuring you have access to the best water quality throughout your RV adventures.
