Can a Pur filter turn salt water into drinking water?

Most water filtration-type devices will not be certified to reduce sodium. Check the label to see if the product is certified to reduce Total Dissolved Solids or TDS.

A filter can separate an insoluble solid from a solvent.Salt is a soluble solid in water and therefore it cannot be removed from drinking water by using filters.To remove salt from water,the water has to be evaporated out of the solution and condensed back into water into another container leaving the salt at the base of the container which is heated to crystallize and cooled.
