First of all, what’s the difference between a salt based water softener and a salt free water softener? Salt based water softeners use a process called ion exchange which is basically exchanging hard ions (hardness minerals which are calcium and magnesium) for soft ions which are in this case sodium. Salt free water softeners use a more complex process where hardness minerals are not removed but they are retained, turning them into hardness crystals which will not adhere to your pipes and you will be avoiding this build-up in your plumbing. Salt based water softeners are more effective in softening water and salt free water softeners are actually water conditioners. But I want a water softener that’s not using salt. Which are the best salt free water softeners? We have gone through the top rated salt free water softeners and here are the top 5!
