Soft and lightweight, Salter 16SOFT Nasal Cannulas provide a higher level of comfort and softness to oxygen therapy users. 16SOFT’s nasal prongs and faceplate are made of an extra soft material that gently curves to conform naturally to your nostrils and upper lip. The cannula’s tubing is also exceptionally soft and pliable, stretching as you move to reduce dragging and pressure on the tender areas around your nose, face and ears.
