first off if salt free systems actually worked every company would sell them. Second of every company that sells a salt free system still sells a salt based system. Why? Because there’s a market for it those of us who actually care will only sell what they know truly works. The reason you have a salt based System is inside your water there are inorganic minerals that are negatively charged ions. When the salt binds to the Resin to create a positively charged ion, these resin beads prevent these minerals from ever passing through every week to two weeks, it goes to a regeneration called an ion exchange where it recoats the resin beads thus process will happen over and over again. Now we’re not actually pumping sodium into your home so if you’re worried about health issues you’ll be fine.
The answer is NO! The minerals in water are called inorganic minerals, which means they are not the same as organic minerals which is found in red meat, fruit vegetable, milk etc. Inorganic mineral have not gone through the process of photosynthesis and absorb the carbon cycle which changes it to a organic mineral. If it’s not organic then the inorganic minerals can not be used as a source of nutrients in our cell wall like organic mineral. But, this mineral has to go somewhere, so it gets deposited elsewhere in our bodies. Water has a job; it’s to regulate body temperature, moistness tissue in the eyes, nose and mouth, protects body and organs and tissues, carries oxygen and nutrients to cells, lubricates joints, and lessens burden on the kidneys and liver by flushing out waste products. So getting minerals is the role of food not water.
There is more sodium on a single slice of bread than what we will put into your water in a two week period. The city already adds sodium into your water to preserve the chemicals. With the reverse osmosis at you sink there main job is to remove sodium.
