bumping this thread asking for some personal review

I might be paranoid or am not.

So my parents house, they have this Coway water filter, love the function as i can easily dispense cold or hot water on the go. But i noticed this

1) I tend to drink lot more cold water if dispense from the machine.
2) drink 5-6 glass still felt, not satisfied/ drink more then bloated
3) making hot drinks using 3-in-1 the usually milo,hoc choc, nescaffe, taste abit tad different. Pale i would say.

at home, i boil water from filtered source, im using panasonic water filter.. it cost less more. Plus i always have stash of spritzer 1.5L carton box, at least 1-2 carton.

to my personal preference, Spritzer > filtered boiled water > coway filtered water

im not sure about other, but i guess drinking those coway filtered water, i tend to not satisfied and drink more till bloated. still doesnt quiche my thirst . Read about it, it uses RO method of filtration, does RO makes a difference? i do however dislike buying "drinking water/RO water" bottled, and always opt for mineral water when buying outside.
