Drink responsibly

In the western world, and in Sweden in particular, tapwater is so healthy and tastes so good there is really no reason to drink bottled water.

Sodastream is the largest worldwide company to provide products for carbonating water.
The soda maker is not very expensive (the cheapest one costs about the same as 50 liters of bottled water). One carbonator costs about 15USD and can be used to make 60-130 liters of carbonated water (depending on the size) and when it's empty you leave it to a retailer so it can be refilled and reused. The bottles used for the soda makers are either glass or plastic, depending on which soda maker you choose. The plastic bottles are high-pressure resistant, can be re-used for up to three years and the plastic is free fom Bisphenol A and does not give away any phtalates or PCB.

You save money, you save the environment and you're never out of fresh carbonated water.
