We can't pretend to fully understand how the technology works exactly (something about using ultraviolet light to wreak havoc on a microbe's DNA, which sounds pretty awesome) but we do know that clean drinking water is incredibly important — and that up until now, purifiers have been relatively slow, and you couldn't run hot water through them. According to the company, the new system is small enough to be embedded in household appliances, and it works independently of water temperature </quote>
