During our first year in Korea, we were buying drinking water because we were worried that the water in the base will harm us especially the kids. Then afterwards, we decided to just bought a fluoride water filters so we could use the water supply there. It was more economical than buying bottled water all the time. Now that we're back, we have to replace the water filter for our refrigerator so we could use water from it. Before we bought our refrigerator, we used to have a pitcher with filter on it but we no longer use it since we have the fridge. I found a water filter superstore online that sell different kinds of water filtration products.
