All 3 carbonation levels are less carbonated than a soft drink out of a can or bottle.
Which Carbonation Level Should I Choose On The RF31F French Door Refrigerator?
Choosing the level of carbonation is something you will have to decide on based on what tastes best to you. Just to give a general comparison, Level 3 is similar to Perrier. Levels 1 and 2 are more similar to San Pellegrino.
