Does reverse osmosis remove calcium, potassium, and sodium?

Yes. RO removes 95+% of everything.

Thank you,

Well, yes, but calcium is hydrophobic and potassium and sodium are hydrophilic. In other words, membranes love sodium and potassium because they are water soluable and wash away very well in the concentrate (waste) flow.

Calcium is insoluable and forms crustations. 'Calcification' means to become rock. Even though the permeate water is calcium free, the membranes will quicky fail from high calcium form influent water.

Get a softener....
