I never thought I’d use a water bottle to filter my water at home until I tried Water-to-Go, but now can’t drink London tap water without it! You can really taste the difference, it is so much better! I also now use it at work, and my children use them for school. Cycling to work or 5 aside, it’s great to know that you are getting clean chemical-free water, and can fill up from the washroom, so I’m saving a bundle on bottled water, and reducing plastic waste. Great idea, great product!
