Gather and add your fresh basil and prepared lemon and cucumber to your carafe.
Fill carafe with filtered water.
Place in fridge overnight (this allows ingredients to steep).
Pro tip: You can keep refilling your carafe with filtered water for about a week or so. Use your best judgement, of course.
Pro, pro tip: toss used fruit, veggies and herbs into your compost bin, rather than the trash or garbage disposal.
