The Polyfilter will actually remove a majority of harmful metals from tap water. The main drawbacks to it's use apposed to an RO
unit is it will not remove fluorines and can end up being a costly alternative in the long run depending on the amount of use. Fluorines are quite harmful to marine animals. If your Municipal water company does not add fluorines, what you propose will work.
Make no mistake, they are an excellent means of water purification but cannot be compared to the longterm costs of an RO

Depends on the water quality you have. The higher the TDS
, the more the need for added filtrants. Without the DI
attachment you would still have the possibility of some silicates unless using a Hi-S membrane. With DI
the silicates are very greatly reduced.
