There are a wide range
of water filters, purifiers, and methods of water purification
available on the market today. In reality, there is no single filter
or treatment that will eliminate 100% of every contaminant from your
water. Many technologies target only a specific type of contaminant
and may be completely ineffective against others. Typically, most
higher-end systems use a combination of filter technologies to
achieve the best results. It is nevertheless important to choose a
system that specifically targets the known or potential contaminants
in your personal water supply.
To
help you gain a better understanding of each major home water
purification technology, please consult the Comparison Chart
