With a varied diet this probably does not matter. Another challenge is when the filters unintentionally make the tap water worse over time. A recent study of PoU Point of Use reverse osmosis water filters revealed widespread bacterial contamination in the treatment devices.
Other studies have come to similar conclusions. The use of reverse osmosis filters is only advisable if the devices are constantly and carefully maintained. Assessment of the extent of bacterial growth in reverse osmosis system for improving drinking water quality. This also applies to activated carbon filters that trap, but do not kill bacteria. Because the filter cannot kill bacteria, it may actually becomes a breeding ground for the microorganisms if not changed regularly.
An old, unchanged PoU filter can be dangerous because its use may add bacteria, which had been killed in the tap by chlorine, back into water.
As long as the filters are changed as per instructions this risk is minimal. Similar tests by a laboratory in Germany concluded that 24 out 34 filters tested increased the amount of bacteria. University of Berkeley on December 6, Microbiological contamination of drinking water in a commercial household water filter system. Verdict: A fit for purpose quality water filter will vastly reduce the risk of contaminants in tap water and therefore probably be healthier than tap and bottled water.
The wrong water filter or a poorly maintained one could however increase risk. All three types of water including bottled mineral water, tap water and filtered water are generally safe to drink in Europe. Therefore the choice is really about eliminating risk and thus improving long term health prospects. Fully eliminating risk is impossible, and because gauging risk is so difficult, safety is really a matter of managing risk to a reasonable degree, not trying to eliminate them altogether.
Safe and risk-free are different things. In conclusion, filtered water is healthier. A quality water filter independently tested for the type of tap water in your household will reduce risk and thus likely have long term health benefits. Comments, questions or feedback.

We proved our problems, my underactive and my husbands stopped working were down to fl;uoride in the water as we had never lived with tap water fluoride anywhere else and are elderl;y. We stopped using tap water for cooking or making up and food or drinkling whether hot or cold.
To begin with we took one sea kelp tablet, for iodine each evening after our meal and within a year my husbands thyroid was fully working and mine up to normal. We stopped the kelp but stayed off tap water and have been fine ever since. Medical science admits fluoride can be harmful to the thyroid.

And the AQ faucet is available in three finishes brushed nickel, polished chrome, and oiled bronze , whereas some competitors give you no choice.
That means the AQ takes up significantly less room in the sink cabinet, can fit in cramped spaces where larger systems would not, and leaves more room for under-sink storage.
