Reverse osmosis is an amazing technological innovation that provides fresh water from seawater in areas around the world where there are water shortages, and is very effective for industrial cleaning of contaminated wastewater. It can also be a good solution for household water when conditions require it (e.g. kidney failure). However, in most cases municipal water is safe to drink and a quality activated carbon tap filter will provide fresh, tasty drinking water at a lower cost and with less water wastage.
Bacteria have historically been a major problem in activated carbon and reverse osmosis (RO) filters. In fact, many tests have shown that there are more bacteria in filtered water than in unfiltered water for RO filters and RO jugs. The solution to this is to use silver impregnated activated carbon, but this is bad for the environment and can also cause some health problems.
TAPP Water has chosen to use the highest quality activated carbon (Jacobi's Aquasorb HS) without silver. We have weighed up the pros and cons of including bacterial inhibitors and, based on tests, have found that this is not necessary. Tap filters have an advantage, as the water passing through has a relatively high pressure.
