What is the difference with this and the inspiratory muscle trainer?

The primary difference is that The Breather is both an inspiratory and expiratory muscle trainer. The combination of both IMT and EMT has been demonstrated to be more effective than just one alone. The Breather is also highly customizable. With 6 inhalation and 5 exhalation settings, The Breather can be finely attuned to each patient's needs. See a whitepaper on the subject here:
