Acapella Vibratory PEP Therapy Devices

The Acapella is a handheld vibratory positive expiratory pressure (PEP) device used to loosen and move mucus out of the airways. As the patient exhales through the device, it combines back-pressure with airflow oscillation — the two mechanisms that help mobilize secretions and keep small airways open. It's a common part of airway clearance routines for people managing COPD, bronchiectasis, cystic fibrosis, and post-surgical recovery, and it works in any position, which makes it far more practical than gravity-dependent postural drainage.

One of the most common questions is which color to choose. Acapella models are differentiated by expiratory flow capability: the DH (blue) is designed for patients who can sustain higher expiratory flow — 15 LPM or greater for three seconds — while the DM (green) suits lower flow rates below that threshold. Both use a dial to adjust frequency and resistance, letting a clinician or therapist tailor the therapy to the patient's lung capacity over time.

This collection carries genuine Amsino International Acapella devices, including the Acapella DH Vibratory PEP System (21-1530) and DM Vibratory PEP System (21-1015), both single-patient-use units supplied with a mouthpiece. For clinicians who want to combine PEP therapy with aerosolized medication delivery, the Acapella Duet Kit (27-9000) bundles the Duet device with a mouthpiece, ten Portex small-volume nebulizers, oxygen tubing, and collapsible flex tubing in one package.

The devices are easy to clean and disassemble for home use, and the adjustable resistance means one unit can serve a patient through changing lung function. If you're comparing options, the Acapella Choice line offers a version that fully disassembles for cleaning and is dishwasher-safe — worth considering for long-term home therapy.
