I actually bought this by mistake when I was buying the descaling kit for my San’s water purifier, but after doing some research on this water bottle that was kind of expensive to be honest, but it’s nice to know that I’m not drinking as much bacteria cause I hate to admit, but I do not clean my water bottle on the daily anyhow I love the water bottle. It does what I need it to do and in the future if San ever decides to make a hydrogen water bottle, I would definitely purchase that one as well.
