The StillPure Filtration System from Franke Kitchen Systems monitors water usage via Bluetooth technology. Linked to a smartphone app, it tracks how many filtered gallons of water a household consumes and conveniently alerts users when it’s time to change the filter. The system also improves the taste, odor and color of water by removing harmful bacteria, parasites and cysts, chlorine, and lead — allowing users to enjoy naturally fresh water directly from the kitchen faucet. The system is compatible with any Franke point-of-use faucet, including single-source models and three-in-one faucets that produce hot, cold and filtered water all from one spout. 800-626-5771; www.frankeksd.com.
