Is under counter water filter worth to buy?
Date back to about a decade ago, Americans don’t pay
much attention on water pollution issue. So the under counter water filter isn’t that necessary
in the US households. Because they believe that the US municipal tap water has been treated and
tested under vigorous procedures, which ensures drinking water safety.
It’s supposed to be so. However, non-stop water safety
crisis occurs that suggested otherwise. Recently, drinking water in Flint, Michigan was found to
contain high level of lead, poisoning the residents, especially children.
It turned out that, though the water was certified to
be safe out of the factory, it traveled to your home with various contaminants along the way. In
this case, it carried lead from the old pipes to the homes of over 100,000 residents.
Thus, the sole reliance on factory’s treatment to our
drinking water is not enough. There is a very high chance that your drinking water comes with
lead, chlorine, bacteria, and a bunch of other contaminants that can lead to serious health
problems.
In all, to meet your household daily water needs for
drinking and cooking, the countertop and under-sink filters are your best solution.
