Our Technology
By pioneering ground-breaking ERM filtration technology, we aim to provide access to clean drinking water to all.
Our promise
Restoring hope through innovation
It is through our deep and personal understanding of the challenges so many face that we strive to make the world a better place. Fully immersed in the very problem we are solving, PAKVITAE is committed to providing clean water for those who have no access to it.
With a team of leading scientists, we have developed a technology that brings the promise of guaranteed purity and reliability to everyone, everywhere.

A life-saving innovation
Thousands of fibres, one powerful filter
The team’s relentless pursuit of a solution that could fulfil the promise of clean water for every person resulted in a ground-breaking new development. Created using innovative ERM (Esoteric Resistive Membrane) technology, thousands of intrinsically anti-microbial hollow-fibre membranes work together to make one highly effective filter that delivers the purity everyone deserves.
- 0.1-micron pores block bacteria, parasites, cysts and plastic particles.
- Huge surface area gives a high flux rate — up to 60 L/hour at low pressure.
- Minerals and dissolved salts pass through, so taste stays natural.
The magic of ERM
Why our membrane stays strong
Kills on contact
As soon as microbes in contaminated water touch our membrane surface, they are killed by zinc — the element built into our intrinsically anti-microbial membranes — and the dead microbes are washed away, ensuring no bio-fouling.
Nothing leaches
Most chemically treated membranes rely on compounds that break away and leach into the water, leaving open pores and making them weak within days. Ours is made with the anti-microbial compound, so it stays effective for extended periods.
Self-renewing backwash
Thanks to ERM technology, a simple backwash removes all dirt and clogging — essentially renewing your membrane every time you clean it, with no extra effort.
