Isn't that taste chlorine from the sanitation process?
Either way I actually do assume water filter companies lobby to keep public water as subpar an option as possible, there's certainly no incentive not to.
It doesn't bother me for drinking, but I've gotten in the habit of keeping an open (loosely covered would probably work too) pitcher of water in the fridge for making coffee, so it sits at least overnight before use, and dissipates some (having already served its purpose.)
Somehow I doubt “Big Filter” has the kind of money and clout they would need to pull that off. I’d accept being proven wrong, but I just doubt it in the absence of seeing proof.
Most of the taste problem that’s in our water “on purpose” is chlorine and it’s not added out of spite, it’s added for sanitary reasons.
Apart from me mixing up chlorine and fluoride, my comment was a bit hyperbolic - of course, there's no Big Filter industrial complex :)
I haven't done a lot of research on how to clean water, but e.g. in Germany, tap water isn't chlorinated and thus has a much more neutral taste. And it's very much regulated to a high standard.
