How do I pick the best home water filtration unit for me?

In an effort to reduce the exposure to toxic compounds such as PCBs, pesticide residues, nitrates, and heavy metals such as lead, mercury, and cadmium in the normal home water supply, roughly two million home water filtration units are purchased annually. The best home filtration unit depends on the predominant toxin. For example, if the primary toxin is lead, a carbon filter provides very little benefit.

This is significant since carbon filters are the most popular water purification units sold. To determine the safety of your tap or well water, contact your local water company.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
