About water, yes Newyorker advised me long ago - to only drink bottled water. Having moved to rented house since Feb '15, I am using the OSIM uPure filter since then. We (and friends) drink/drinking straight from tap. And all were alright. Hence thought I might put info here for value sharing.
The filter apparatus is free and has adaptors to fit many kinds of *round* kitchen faucets.
There is a window on the side to check the cartridge filter. If it turns *very* dark/red brown, then to change the cartridge , which is easy too. It's been more than 4 months now and the cartridge still looks new. (lucky perhaps that the estate I'm in had laid good pipes ? not sure).
The replacement cartridge itself is made in Japan. It costs S$39.90. (Reading the package now) - (A) The Granular Activated Carbon removes chlorine disinfectant, mould smell and other odours. (B) The Filament Membrane removes bacteria, rust, mould, turbidity, very fine particles. (C) The Filter removes microscopic stains, red rust, coliform bacilli, general bacilli and protozoa.
Has saved me alot of trouble buying/stocking-up bottled water - drinking, making coffee, cooking. And none so far, including myself having a truly sensitive stomach, has any stomach or bodily problems from drinking water straight from my tap (yep I dun even boil the water). 4 months now and still counting.
Just to share. Cheers.
