It is not. Breathing at altitude is strenuous because of the partial pressure of oxygen, not because three plastic sieves on your face make drawing a breath more laborious. You want to improve your cardiovascular ability, do regular cardio. You want altitude training, go to high altitudes. Don't waste your money on this snake oil. Too lazy to format or sage.
