Is it necessary for each household to use a water filter? What kind of filter is needed?

For obvious reasons, a water filter is needed for each household. A fact that we all need to accept, is that the springs and the boreholes do not provide the same water quality as they used to provide few decades ago (environment pollution, fertilizers, industrial piping).

Therefore, the water filter use is reliable. The water filter needs to be selected by an expert who has to come and measure (via a chemical analysis) the water network and have a thorough discussion regarding the problem and the solution. Every six (6) months, the Veluda company performs a (chemical) analysis in all areas of operation, thus becoming aware of the problem.
