How to choose a coffee maker water filter?

As we all know, water is the most important ingredient in a cup of coffee, accounting for 98% of the coffee, so there is no delicious coffee without good water.

When choosing a coffee maker water filter, you should consider three key functions:

1. Reduce sediment (Sediment reduction)-the filter must remove algae spores and small particles of dirt, sand and sand to protect the water flow of the coffee machine and prevent the boiler from accumulating sediment to form scale. Because there is a certain amount of Hardness in the water, calcium carbonate and magnesium carbonate will precipitate and scale will be formed. Scale is definitely a headache for coffee makers, because too much scale deposits can shape pipes and boil flavor, just as people's blood vessels are blocked by fat and burst blood vessels. However, it is impossible to use soft water completely, because the water with too low pH value will cause Corrosion of the pipeline. Especially under high temperature and high pressure, pipeline corrosion not only shortens the service life of the machine.

two。 Reduce chemicals (Chemical reduction)-reduce chemicals such as chlorine, which has a negative effect on the taste of coffee

3. Reduce the total hardness (Total hardness (TH) reduction): this refers to the presence of magnesium and calcium salts in water. Some of these salts can precipitate and form scale, affecting the cover boiler surface components, valves, solenoids, rubber wheels and flow paths in the coffee machine. Scale can adversely affect water temperature, pressure, steam performance, water flow rate and taste. Although the scale can be removed by a chemical "descaling" machine, the rate of scale accumulation can be significantly slowed down by using a proper filter.
