Best Answer

There is variable here. It depends on what water your filtering and what filter you're using. Depending on your location the mineral density of water will vary. Hard water being rich in mineral and soft water being poor. The harder the water the weaker your extraction will be. Extremely soft water like distilled or reverse osmosis water will leave you with a over extracted cup of coffee.

In general it is good practice to use a carbon filter system which removes impurities but retains minerals. However if you believe your water is too hard and you're under-extracting, try using a home filtering system that removes (some) minerals.

When it comes to making coffee, hard water is inferior because its high mineral content mutes the flavours of coffee. (Note that hard water is also worse for your coffee machine because it causes greater limescale build-up.) Soft water makes better coffee due to its lower concentrations of minerals.

Which types of filters are used in brewing coffee?

In all the fuss over finding your favorite coffee beans and brewing method, there may be an aspect you've forgotten: filters. They don't get a lot of glory, but filters are indispensable to the coffee brewing process. There are three main types of coffee filters: paper, metal, and cloth.

How do you prepare water for coffee?

First, bring cold water to a boil in a kettle. If using whole beans, grind the beans to a uniform consistency similar to granulated table salt. Meanwhile, put a filter in the brewer and rinse with hot water. This removes the papery residue on the filter and warms up the brewer, keeping your coffee hot for longer.

Answer 2

In addition to Charlotte's cook answer I'd note that heating / boiling water removes most of the common volatile compounds such as chlorine (not minerals) that may affect taste. So your boiled water would be more neutral in flavour than the same water straight from the tap.

So depending on your water supply, there is often less need to filter for making coffee than cold beverages.
