Can't seem to find online how Singha drinking water is prepared... I'm wondering how purified it is (I.e., reverse osmosis, uv, ozone...). I inhaled some of it by mistake (choked while drinking and it poured down my nose) and I'm concerned of getting and infection (some nasty amoebas can be really dangerous). Anyone with info or similar experiences? Please help! thanks a ton!
