Choosing the best water filter for your espresso machine is an important thing that you have to do to keep your espresso machine’s performance and prevent you from making a bad coffee. There are three key performances of espresso machine water filter that should be considered. They are sediment reduction, total hardness (TH) reduction, and chemical reduction.
Tips to Choose The Right Espresso Machine Water Filter
Every time you make your coffee, there is always dirt left in your coffee machine. The dirt comes from the oil extraction from coffee beans you brewed oil that retained in your espresso machine water filter. If it is allowed in a long time, it can form scale in the wall and the pipe of your coffee machine. In the end, you will find your espresso machine full of sediment and hard to be cleaned. One of the key performance of espresso machine water filter is the sediment reduction.
The sediment reduction is the ability of a filter to remove small particles of dirt, algae spores, sand, and rust in order to protect the flow path of your coffee machine. The filter with good sediment reduction ability will also prevent the boiler from precipitation. If you wrongly choose the espresso machine water filter with the weak performance of sediment reduction, you need to use a softening medium in a water filter to reduce scale formed by accumulating sediment.
Total Hardness (TH) Reduction
The other important performance of espresso machine water filter is total hardness reduction. Total hardness (TH) is a measure of magnesium and calcium salts in the water. It is important because these salts can precipitate in the boiler surfaces, valves, elements, solenoids, and water flow paths to form scale. This scale can adversely affect water flow rate, pressure, water temperature, steam performance, and your coffee taste.
Although you can remove scale by chemically descaling the espresso machine, using an appropriate filter with a good total hardness reduction ability will minimize the accumulation of scale. Routine descaling is not recommended because descaling requires the use of acid that can ultimately degrade the thin copper tube of your machine. So, it is better for you to choose the right espresso machine water filter with high TH reduction performance.
If total hardness reduction refers to the ability of the espresso machine water filter to reduce the presence of salts dissolved in water, the chemical reduction is referred to the ability of the filter to reduce the chemical compounds such as chlorine that can negatively affect the taste of your espresso. Similar with total hardness reduction, actually you can clean up the chemicals by descaling the espresso machine but again it is should be avoided to prevent your machine from unexpected damage. Choosing the right espresso machine water filter is the best option.
Espresso Machine Water Filter Specifications
Mostly, the espresso machine water filter available in the market is working properly in the environments where TDS is less than 300 ppm and TH is less than 160 ppm.
Making a cup of good coffee is a long process. You shouldn’t let the wrong choice of the espresso machine water filter affect your coffee taste.
