The popularity of bottled water has surged over the past decade or so due to a variety of reasons. While bottled water offers you the convenience of being able to grab a bottle and go, there are many downsides to this as well. Firstly, the cost factor is a major issue as it can become a very expensive habit especially if you buy multiple bottles in one day. Secondly, when you buy these bottles that is more plastic that is used, which is definitely not a good thing, environmentally speaking. There is also the fact that many of the bottled waters you buy are sourced from public drinking water supplies, so the quality is similar to what you would get out of the tap. One of the best alternatives to buying bottled water is to look at the many advantages of water filters for drinking water. These are available in a multitude of shapes, sizes, and configurations. There are drinking water filter system models that hook onto the faucet in your sink to provide you with pure water, while there are portable water filters for tap water that fit into a small bottle you can easily carry around.
