Everyone knows it's important to stay hydrated, but not every source of drinking water is clean enough to put in your body — make sure your daily dose of hydration is healthful with the Soma Water Filter ($50). The blown-glass container holds 48 ounces of filtered water, and the filters are made of environmentally-friendly materials like coconut-shell carbon, silk, and a plant-based casing. They're biodegradable and don't result in nasty bits of black charcoal in your water. Get fresh filters delivered to your door every two months with an available subscription service. Best yet, every filter sold helps provide clean drinking water through charity: water.
