Quite often there are wells available at holiday homes. They could bring ease to the living if they could be used as drinking water and there would be no need to carry the water with you. However, those wells often contain some unwanted substances that should be filtered.
In our Pikkuvihreä web shop we have a selection of light drinking water purifiers that can be used to filter the water. If possible, it would be a good idea to test the water first. Thus, it would be known what kind of filter would suit your need the best.
