Frequently asked questions about water filters

Dutch tap water complies with legal standards, but that does not mean it is completely free of unwanted substances. Research shows that tap water can contain traces of PFAS, microplastics and heavy metals, especially via outdated pipes. Read more about the quality of tap water in the Netherlands. A home water filter offers extra assurance on top of the purification by the drinking water company. For the PureFilter Mineral+ the following was measured: all 40 tested chemicals reduced, from 75% to 99.97%. 83% to 85% less PFAS, including PFOA and PFOS. Lead, mercury, arsenic and cadmium brought below the detection limit.

Safe and optimal are two different things. Tap water is legally allowed to contain small amounts of chlorine, limescale and other substances that affect taste and smell. No chlorine taste, no chlorine smell: 99.97% less chlorine. Swedish Mineral Rock™ adds calcium, magnesium and potassium in the final filter step and gives your water a soft, fresh taste.

That's an understandable question. The government guarantees safe tap water, but safe means that substances are below legal limit values, not that they are completely absent. Independent research shows that Dutch tap water can contain measurable amounts of PFAS and microplastics. Moreover, legal standards for some substances such as PFAS have only recently been tightened.

Swedish Mineral Rock™ adds calcium, magnesium and potassium.

A water softener removes limescale and replaces it with sodium, useful for appliances but less suitable for drinking water. A water filter works differently.

Lead, mercury, arsenic and cadmium brought below the detection limit. Swedish Mineral Rock™ adds calcium, magnesium and potassium.
