Franke’s 3-in-1 filter faucets produce hot, cold and filtered water all from one faucet — reducing the expense and eliminating the waste associated with purchasing bottled water. The faucets pair with the company’s filtration app, which monitors usage of filtered water and reminds users when it’s time to replace filters. The faucets use a multistage filtration process that kills bacteria and rids tap water of chlorine, chloramine and other chemicals.
