You filter in, and you filter out. It seems like such a simple process, and yet it is. To think that this is about all it takes to purify your health if you will is astounding when you think of it. For many years now, mankind has been ignoring the basic laws of nature and subsequently, of survival. Speaking of which, there is suspicion among many thinkers that it is the philosophy of the survival of the fittest that has driven many of the modern technologies of today that we are being forced to embrace.
The feeling goes that if you do not embrace them, you will simply be left behind, and the world carries on without you. All so untrue. In case you have not noticed, many progressive thinkers, and with a conscience to boot, are returning to their roots. They are returning to nature, taking a back to basics approach, and implementing what has always worked before. The consequences of modern technologies and rapid industrialization have left its perilous mark.

As was said, the consequences of heavy polluting have seen the need to create workable checks and balances that are good for everyone. To clean rivers, dams and lakes is not an overnight exercise. Even more so when you think about all the piping installations that carry your everyday basic needs water.
But you have the power in your hands. It is within you to ensure that your own installed water filters are able to take good care of your health and that of your surrounding communities.
