How to select the right filter cartridges for my water problems?

When choosing appropriate filter cartridges for your filtration system installed at home, apartment or office the following criteria need to be considered:

a) the origin and level of water pollution
b) the use of water (ie, for immediate consumption, for bathing or washing)
c) the location of the installation of a filter or filtration system, i.e. the water at the point of entry (POE) and point of utility (POU).

These factors should be taken into consideration whenever you buy filters or filtration systems.
