As someone who lives at the other end of Asia, I can attest to tap water being undrinkable and bottled water the norm. I would also add all these comments saying “get a filter” are just setting themsleves up for problems down the road. UV flashed, RO, carbon filtered water is clean AF but has been stripped of essential trace minerals and micronutrients. In order to have efficient hydration, we need to reacquire those somewhere… so unless commenters are planning on gorging down salty snacks and chugging sports drinks behind their water, I would refer people to ConcenTrace products in order to do that. I’m not shilling for the company but I am a happy customer. There are probably other ways to go about this, but I’m not aware of them; a simple scoop or drip into my water mug is easier than sourcing various and combining them on my own.
