Maybe you cooking skill just improved lah. Unless you use muddy water vs clean water - water is water mah, it's not like milo and tea, different taste.

I say this is just bullshit scam. Like selling fresh air from a can crap.

You've installed filter isst? Haha, even I dun dare to drink our tap water without boiling it 1st but then again, when we eat or drink outside we dunno if they really used boiled water or not oso.
