Kiyo is a natural, plastic-free way to filter your water to make it the best tasting drinking water. It also remineralizes water, adding the minerals we miss most like calcium, potassium, and magnesium. Beyond that Kiyo is environmentally friendly. Every part of our product can be recycled, reused, or composted. Above all, we are committed to being a carbon neutral organization and we offset all our carbon emissions by planting trees.
