"feels like acid hitting my skin", exactly! It's horrible. I had a bit of luck when I found a filter that is so strong it takes even the chlorine out of the water. Another post on this sub mentioned it and I figured I had nothing to lose. It's night and day the difference using this filter. Found it on Amazon https://smile.amazon.com/gp/product/B08ND7NL3C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
The one that I was originally recommended was on US Amazon, so hopefully this works for you: https://www.amazon.com/gp/product/B08ND7NL3C/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&th=1&pldnSite=1
