The Airofit PRO is the most advanced consumer breathing trainer available. It measures RMV (respiratory minute volume), inhalation flow rate, exhalation flow rate, and breath hold capacity in real-time, allowing precise tracking of respiratory function improvements over time. The companion app provides structured COPD-specific training programs developed in collaboration with pulmonologists, with progressive resistance adjustment. The data it generates is clinical enough to share with your respiratory therapist or pulmonologist.
