Laundry is not such a big deal, because while chlorine is very dangerous, it is also very volatile. Meaning it evaporates at a very low temperature (much lower than water.) The best thing to do with laundry is to simply expose it to the sun, although the high heat of the dryer will take care of most of the chlorine anyway. If you need water for something, and can’t filter it, the easiest way to get rid of chlorine is to just set the open container of water out where the sun can get to it for a few hours, or just boil it.

That won’t get rid of fluoride though. And fluoride WILL get into your skin through clothes, and direct water contact. Filters that take out fluoride are VERY expensive, and really bulky. For most of us living on a tight budget or in rented spaces, fluoride is just a fact of life, unless you can get your city to stop adding it to the water.
