This technique eliminates the need for filters and instead uses an electrical field to separate contaminants.

This seems like a nice thing to have stored away in a remote area in case of emergency. Part of a comprehensive pepper kit. But it sounds over engineered and expensive. For example a reverse osmosis can desalinate water and all you need is a filter and some way to pressurize one side. You can fit enough filters to desalinate thousands of gallons if water in one suitcase.

They are trying to hype up the new technology, but it is not yet developed enough to be more impressive than what we already have.
