Best OPEP Device for Airway Clearance – A Non-Invasive, Unmedicated Path to Better Breathing

Are you ready to breathe a sigh of relief? OPEP devices, or Oscillating Positive Expiratory Pressure, give people with asthma, COPD (Chronic Obstructive Pulmonary Disease), and cystic fibrosis a chance to breathe a little easier. We’ve discussed how effective lung exercisers are like the Airofit and Airphysio. If you haven’t checked out the best lung exercisers, click here now. 

Now we want to showcase some of the best OPEP devices for people who suffer from one of these conditions or have a loved one who does. These revolutionary, non-invasive tools might mean the difference between staying healthier longer with fewer breathing issues. We’ll explain what an OPEP is and how it works. Then, we’ll describe the different types of OPEP devices and show you some we recommend.

What are we waiting for? Let’s get started!

What is an OPEP Device?

OPEP stands for Oscillating Positive Expiratory Pressure. These devices create oscillations or back-and-forth movements throughout the airway, allowing airway clearance when exhaling. These movements also help disperse and remove lung mucus, resulting in better airflow. Reducing mucus and promoting better airflow lowers the risk of lung infections and increases lung function.

People are excited about OPEP devices because they are a drug-free, non-invasive way to treat lung conditions. 

How They Work

When you exhale into an OPEP device, it increases pressure in your airways. The increase in pressure allows your airways to maintain their shape, staying open as air leaves your lungs. This process helps to prevent airways from collapsing, which happens for people with asthma, COPD, or cystic fibrosis.

In addition to helping keep airways open, the oscillating effect of OPEP devices maintains movement throughout the lungs, decreasing mucus build-up. It’s a natural process of expelling lung mucus without hard steroids or other medications.

Types of OPEP Devices

There are two different types of OPEP devices, so let’s look closely at each.


Gravity-dependent OPEP devices use gravity to support the oscillation when you exhale. Because of this, it is necessary to have the OPEP device positioned in a certain way relative to the ground to work correctly. It looks like a pipe with a ball or disc placed inside. When a person exhales into the gravity-dependent OPEP device, the ball or disc moves, creating an oscillation that adds pressure to your airways. This process keeps airways open for better airflow while loosening mucus inside the lungs. 

Gravity Independent

As you may have guessed, gravity-independent OPEP devices do not rely on gravity to function. Instead, they use counterweighted plugs or magnets to deliver pressure during exhaling. These OPEP devices are great in any position, making them more convenient for people with mobility issues.

Best Gravity-Dependent OPEP Devices

Breather Fit

We like the Breather Fit device for athletes or people who want to increase their lung capacity. With the help of gravity, this device requires no battery, refills, or liquids to function. Exhale through the Breather Fit device and let the adjustable pressure settings build up your lung capacity and increase airflow. Instructions for use come with the product and are available online. It fits in your pocket for use anywhere.
