i am drinking normal water for ages. now got big external intact outdoor filter and cheap coway rm200 filter in kitchen. boil water and drink. very alive and healthy

I'm surrounded by family and friends that is full of doctors, pharmacist, nurses...never seen their house install any fancy water purifier pun.
Also like I reply in my post above...oversea people drink from tap directly...all doing fine
