It's basically a water purifier. That will make no difference to COPD or any other condition. The water will taste good and probably not have all the chemicals they put in it to make it drinkable, but it won't fix any chronic conditions like COPD. The things that will make a difference in breathing, energy, fatigue, etc. are things like quitting smoking, getting your weight as close to normal as possible and exercise, exercise, exercise.
