The StillPure under-sink filtration system from Franke Kitchen Systems is equipped with Bluetooth technology to monitor water usage from a smartphone. It improves the taste, odor and color of water by removing harmful bacteria, parasites, cysts, chlorine, and lead, allowing users to enjoy naturally fresh water directly from the kitchen faucet. The app works with the FM100 module, a Bluetooth monitor that easily attaches to the filtration system and tracks how many filtered gallons of water a household consumes, which translates into fewer plastic bottles in landfills and household money saved. It also sends alerts based on actual water usage when it is time to change the filter. 800/626-5771; www.franke.us.
