One of the benefits I noticed right now….today….using the Elevantion Training Mask… .is my lack pr urge to breathe through my mouth, strong odors are not making me cough at a first whiff (so I noticed-using sensitive to gas exhaust fumes, trash odors….)….so can breathe soooo comfortably with my nose in and out….kind of relaxing to be honest..After my first day of using it!!!!!! Awesome!
