Think about it: Water is among the most important things for humans, only second to oxygen. Without it, we can’t live for more than a few days. Needless to say, it’s an important part of your everyday life, so why not invest in good drinking water?Sure, you can buy purified water, but it gets expensive over time, not to mention the time and trips to the store. Then, there are the complicated filtration systems that can be installed under the sink, but those are also mighty pricey, hard to install, and often not even a viable option for renters.
