How good is the water quality of my tap water?

You should ask yourself this question especially if you live in a larger city, near industrial areas or maybe even in an old building. Although it is often said that the drinking water quality in Central Europe is a good to very good quality, many consumers do not know that these measurements are based only on the waterworks and the public lines. The quality controls thus end at the water meter in the house.

A recent report from consumer advocates in 2018 has shown that drinking water in cities such as Münster, Bonn, Berlin, Dortmund and Essen is the most polluted. Obsolete pipes in the old building can get copper and lead into the tap water. According to the Drinking Water Ordinance, the lead content must be less than 0.01 milligram, the copper content less than two milligrams per liter.




Why should I filter my drinking water?

As lime-containing tap water leads to the calcification of machines, regular decalcification must be carried out. Lime water will damage your coffee machines, refrigerators, washing machines, dishwashers and all other household appliances that heat tap water. Especially coffee lovers should know how important lime-free and unloaded water is when making coffee. Pollutants such as metals, pesticides, gadolinium and antibiotics have an influence on the taste of your coffee. Various coffee associations in Europe recommend an overall hardness between 7-12 dH and a carbonate hardness between 3-4 dH and a pH of 6.5 to 7.5 for optimum coffee aroma.

Many coffee machines have a holder for filter cartridges in their water tank. For a long time these cartridges could only be obtained from the manufacturers of the coffee machines and often had to pay an excessive price. However, there are now compatible filter cartridges on the market, which are produced by various other companies. As a result, customers can save up to 40% of their costs and receive filter cartridges of equivalent quality. A good example of this would be the Jura Claris Blue. One of the big providers in German-speaking countries is Giratec GmbH.




How do I test my water quality myself?

To test contaminants and contaminants in tap water, they may have a sample examined by their local water supplier. In addition, it makes sense not to let the water stand in the line for a long time, but to drain it fresh. The cheaper and easier way to do it yourself at home is the quick water test with a test kit from AquaNatura. This measures the top ten contaminants and components in the water. These include, for example, the pH value, the bacteria, the chlorine content and the water hardness.



How do I filter my drinking water for my household appliances?

In coffee machines by inserting filter cartridges, which are available for the most diverse types of machines, such as fully automatic coffee machines, espresso machines (sieve carrier machines), pad machines and even for filter coffee machines, various manufacturers offer models with built-in water filter. One of the best-selling filter cartridges is the Jura Claris Blue and Jura Claris White, a good substitute for these are the filter cartridges from Aquatec. Like the Jura Claris Blue, these filters have a high-quality filter granulate, good workmanship and can filter up to 50 liters of coffee water. Other well-known brands are DeLonghi, Siemens, Nivona, Krups and Miele.

Refrigerators use special long-term filters that can be used for up to 6 months. These are often two-layer filters, which in addition to activated carbon also have a sediment filter that can also filter out particles such as rust or sand.
