The AffloVest difference

The Clear Choice in Airway Clearance Therapy


AffloVest is a proven high frequency chest wall oscillation (HFCWO) therapy designed to provide patients the freedom and mobility to customize and enhance airway clearance therapy, help mobilize lung secretions, and promote treatment adherence for patients struggling with chronic respiratory conditions. AffloVest is the first fully mobile during use HFCWO vest, and does not utilize bulky generators or air bladder technology.

With treatments often being prescribed for daily sessions, it’s important to have a therapy that fits into a patient’s daily life – not the other way around.

In a recent HFCWO vest preference study, 30 participants wore the AffloVest and an air bladder style vest for 15 minutes each at equivalent settings. AffloVest was preferred for adherence, comfort, fit with lifestyle, and overall preference.


Our patented Direct Dynamic Oscillation™ technology utilizes eight oscillating motors to create individual pressure waves that target all lobes of the lungs. This technology was designed to mobilize secretions by mimicking manual chest physical therapy (CPT).

AffloVest has three levels of intensity to accommodate patient’s individualized needs and three unique modes designed to mimic hand CPT:

Percussion – All motors operate in a pulsed fashion using a regular rhythm.

Vibration – All motors are continuously on, providing deep oscillation of the thoracic cavity.

Drainage – Individual zones activated in succession as therapy progresses up and down to mobilize secretions upward.




With eight sizes to choose from and no age restrictions, AffloVest is the most inclusive portable HFCWO vest available for patients. You can be sure that regardless of size, shape, or body type, AffloVest delivers targeted therapy that fits.

Adjustments can be made with the AffloVest Size Exchange Program, which allows patients to go up or down in AffloVest size as needed, to provide tailored and targeted airway clearance therapy. See Terms and Conditions for program details.


The AffloVest requires a prescription for treatment by HFCWO. Once your healthcare team has decided AffloVest is the airway clearance therapy for you, they can fill out the AffloVest Order form, provide all necessary insurance and medical documentation, and contact a Durable Medical Equipment (DME) distributor to place the AffloVest order.

The AffloVest has received the FDA’s 510k clearance for U.S. market availability, and is approved for Medicare, Medicaid, and private health insurance reimbursement under the Healthcare Common Procedure Coding System (HCPCS) code E0483 – High Frequency Chest Wall Oscillation. The AffloVest is available through the U.S. Department of Veterans Affairs/Tricare. Patients must qualify for coverage and meet their individual insurance’s eligibility requirements.

Coverage criteria and documentation requirements can vary from patient to patient, largely depending on their medical condition, and their health insurance carrier and plan. Work with your healthcare team to decide if AffloVest airway clearance therapy is right for you.
