IIRC Ro is passed thru a series of membranes/filters where as distilled is heated to steam and steam is collected and cooled hence distilled.
If at walmart they have water labled distilled, drinking and spring. drinking and spring are both RO processed.
Also at walmart the gal jugs are in the "water aisle" which is next to the soda aisle
