A few things about OptySun

About our startup

The founders of the startup, Roman and Bohdan, have been dealing with disinfection problems for a long time, but realizing the problem of the lack of drinking water, they added to the team and focused their efforts on R&D, so that in two months we have a working and tested laboratory prototype.

What is new in our idea?

Our idea is innovative, which is confirmed by a patent and consists in the combined use of several cleaning and disinfection agents: membrane filter, UV, ozone. Unique design solutions and cyclic processing make it possible to obtain a synergistic effect, which significantly reduces energy consumption and increases the efficiency of disinfection.

What is our motivation?

There is a war in Ukraine now! Our team is from Kharkiv, a city in the immediate vicinity of the front line, partly in huge destruction. And one of the most important problems is the lack of free access to safe drinking water. We are scientists and volunteers, we want to provide an adequate solution to this problem first in Ukraine, and then throughout the world!

The mass introduction and use of our product reduces logistics costs by up to 40%

Our solution is a portable drinking water purifier that kills 99% of bacteria. That is, our product in no way affects the environment of any climate zone or ecological status and can solve the problem of access to clean drinking water for 9M people (UA market).

Our vision also includes helping to solve a global problem by creating online statistics on the consumption and quality of drinking water in all locations where our product is used.

Our product solves the problem of stable and free access to clean
