I drink a lot of tap water, but always put it through a filter of some sort.
- groby_b 7y agoI honestly don't know. IIRC, you need an ion exchange filter (but they're bad for other reasons) or a reverse osmosis one certified for Cr(VI). https://www.ewg.org/tapwater/ https://www.ewg.org/tapwater/ has a pretty decent guide.
- _0ffh 7y agoIf you don't mind a bit of work (weekly rinsing) and discarding part of the water, I'd recommend a reverse osmosis filter. They're reasonably cheap and beat the crap out of all the alternatives for non-professional users. You'll essentially have to add back some salts after the filtration process to turn it into something that won't demineralise you.
- mdorazio 7y agoTook some poking around to piece together a real answer, but the ion exchange component in a standard Brita filter (or similar pour-through) isn't the right kind to trap chromium (mostly just zinc, copper, and cadmium). You either need a higher-grade ion exchange filter (you can search for "Chromium 6 Water Filter" on Amazon) or a reverse osmosis system.
- 4ntonius8lock 7y agoThanks. Reverse osmosis removes minerals, which isn't something I want. Personally (this is just my perspective) I operate under the theory we don't fully understand the human body, so don't mess with things too much, removing minerals and then selectively adding some back in is not something I think we are well informed enough to do without possible negative consequences. I looked for Chromium 6 Water Filter and found plenty of good options. Truly thank you for the recommendation.
