The "salt-free" systems don't actually soften the water because they don't remove the calcium and magnesium ions that cause hardness. You need a ion exchange system (which is how a salt-based water softener works) or a reverse osmosis filter to remove hardness. If you measured the hardness before and after your system you would find that it is unchanged. These systems are sometimes referred to as "water conditioners". They attempt to "crystallize" the hardness to reduce scale build-up. I don't believe they provide the same feel as softened water. However, if you are happy with the system then that is all that really matters.
