I use a basic one from Home Depot. Takes out chlorine, but not much else
It has been 4 days for me right now, I feel that standing outside in the wind works better then coating myself in fluoride, pharmaceuticals, and pee pee.

I met a gal last weekend who works for a water testing operation, governmental I think.
She says they are always testing high, everywhere. The only thing they do is document it and sometimes, if it is causing noticeable problems, shuts off that pathway. The city water system is pretty gross, she assured me.
