We put a filter in front of our apartment room for drinking water,
but the filter get dirty really quick.
It goes brown and we have to change it within 3 weeks.
Also, we have to boil the water before drinking it.
I really miss drinking a clean water in Japan.
I was drinking underground water when I was a little boy.
I hope the time will come soon when everyone can drink
the pure water without worrying about contamination.
