Pure Water, Perfectly Balanced
The ÌON II is a tankless undersink reverse osmosis filter that removes up to 99% of chemicals, heavy metals, and bacteria. A Vortex stage spins the water in the same natural swirling motion found in rivers and springs, and a final stage remineralizes every drop with calcium and magnesium for fresh tasting water.
Vortex System
Water in nature never stands still. It tumbles over rocks, winds through rivers, and spirals down waterfalls, always moving.
The final stage of the ÌON II brings that motion back.
Its Vortex chamber spins your water in the same swirling flow found in natural springs and streams, the way water is meant to move. What makes every glass taste noticeably cleaner, softer, and more alive.

Frequently asked questions
Here are some common questions about our product.
The ÍON II is a compact, tankless under-sink reverse osmosis system that delivers exceptionally pure drinking water. It removes up to 99% of contaminants through reverse osmosis, while the integrated Vortex system recreates the natural swirling movement of water. As the final stage, the water is remineralized with calcium and magnesium before being dispensed through a dedicated tap, providing clean, fresh-tasting drinking water.
The ÍON II incorporates Vortex water technology after the purification and remineralization stages. The water passes through a specially designed chamber that creates a natural swirling flow, similar to the movement of water in nature. This process is intended to restore the water's natural flow characteristics before it reaches your tap, complementing the system's reverse osmosis filtration and remineralization. Together, it delivers water that is exceptionally pure, enriched with essential minerals such as calcium and magnesium, and fresh-tasting.
