So our water at work is pretty clean from the bad stuff, but it does tend to have a lot of calcium. Lots of the small filters like this...

Seem to be just for removing chlorine and other bad stuff, but I don't see anything about removing calcium. We currently use a unit like this for our coffee machine, and helps a bit but all the valves on the inside tend to still clog up after a month or so due to the calcium buildup.
Is there something similar to the above that I could purchase to just remove the calcium? Thanks.
