Many people confuse water softeners and drinking water filters as being they same thing, although they are very different they can be used together. Lets take a look at the basic differences:
Drinking Water Filters:
Depending on the problem that is trying to be solved depends on which is most suitable, but they can be used together. If you have a water softener installed to prevent limescale build up you can also have a drinking water filter to improve the waters taste, if neccessary. This can be either filtering softened water or having a hard water tap that is filtered. Alternatively filtering either hard of soft water is not compulsory if you are already happy with the taste, but are having a water softener installed. It is personal preference.
If you are unsure what is best for your needs we are always happy to discuss the options with you fully.
