POWERbreathe TrySafe Filter POWERbreathe TrySafe filters are single use filters for use with all POWERbreathe series’ models and should be used when more than one POWERbreathe user wishes to use the same POWERbreathe device, for example when testing the breathing strength of clients on a K-Series model. The filters have been designed to be used with all POWERbreathe models including POWERbreathe Inspiratory Muscle Training (IMT) (Classic, Plus and K-Series) devices and POWERbreathe Shaker (Classic, Plus and Deluxe) devices. If using this filter with a K-Series model, then the POWERbreathe Spacer is also required.
