According to hundreds of studies around the world, tap water that meets the drinking water standards set by the EU, US EPA and World Health Organization is as good as bottled water. If your water tastes bad or you don't trust the local tap water then use a high quality water filter. With a certified water filter by Tappwater you can be confident that your water is safe to drink.
Furthermore, tap water costs less than 0.16 cents / litre. That compares with bottled water, which costs 20 cents / litre or more, making it 200 times expensive (or even more, depending on the brand).
In blind taste tests, 9 out of 10 people could not taste the difference between AquiStream purified water and bottled water.
