Suggestion - Psoriasis and Water

Hi, I've psoriasis since I was 12, I'm now 26. I moved from Ireland to London in my 20s for a few years and when I lived there I had few problems. I moved back to Ireland a few months ago and noticed my psorasis became much worse. I quickly noticed the problem was the water I was washing myself with - it was drying out my skin - obviously due to the some chemical make up. I went on Amazon and bought a shower head filter and an additional water filter (it was called YISSVIC) I'll link both below. I wish you the best and hope it helps you. https://www.amazon.co.uk/DigHealth-Increases-Pressure-Installation-Chlorine/dp/B07PD27T8M/ref=sr_1_6?keywords=shower+filter+head&qid=1578593388&sr=8-6 https://www.amazon.co.uk/gp/product/B07DWPHZBD/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
