Hydro Homies

I want to get better at consuming water and I think my biggest downfall is water quality currently. The water where I live is very hard (and constantly getting polluted thanks 3M) and while I can usually trust what we do at home, there's no way I can trust my work to properly filter the water they provide us. I remember using a filtered water bottle back in high school but I lost that at some point. While I've done some research into what's available results were inconclusive. Any homies got any recommendations for me?
