Yea, forgot to mention, the allergic reaction on my face, scalp and body start subside when i removed the filter. Within a week without any filter my skin back to normal.

can say solved la, but i x paham why using filtered water cause my skin react, and I tried many filtering method, each of them cause me react and skin back to normal after I unfiltered it. But I confirmed the water quality is poor and high chlorine before filter
