By training the flexibility of your diaphragm, you can increase your vital lung capacity. This means you can inhale more oxygen into your lungs with one breath. 

Just like any other muscle group, working on your breathing muscles makes them stronger, faster and more efficient, lowering energy consumption.

Getting your muscles used to perform in an oxygenless environment ensures prolonged ability to perform at high intensities for longer periods.

Improve your oxygenation, blood circulation, and mental concentration to put your body in the right state of tension physically and mentally right before the moments that matter the most.

Frequently Asked Questions

General information about the Airofit breathing trainer

Airofit is a respiratory training solution designed to help you strengthen and improve your respiratory system, using the latest technology. Whether you are cycling, swimming or competing in other demanding sports, having more oxygen to tap into gives you a clear advantage. You will be able to train harder, recover faster – and perform better.

Airofit breathing trainer should be used according to the instructions indicated by the Airofit Sport app.

Airofit focus on total Respiratory Muscle Training (RMT), whereas other breathing devices concentrate primarily on Inspiratory Muscle Training (IMT). Other devices do not provide visual guidance, multiple training sessions and live feedback on the training. Airofit wraps all these features in the mobile application. Moreover, the training sessions are unique and developed with breathing experts to make sure you get the most of your RMT and not just breathing in and out.

AMBU International did a study on an older version of Airofit in 2013. So far, it is the only study done using our product. However, there are countless studies on respiratory training’s effect on physical performance.

We are working with several asthmatics and their feedback is great! However, there are many different types and degrees of Asthma, so we strongly recommend you to first consult with your doctor about respiratory training.

No. All ages can use the trainer, but we strongly recommend that kids under 15 use it with supervision from an adult.

We recommend that you start training 2x5 minutes every day. After a few trainings, we encourage you to train at least 2x10 minutes per day. We strongly recommend that you always take a short break after every 3 minutes of your training.

You should be relaxed and standing or sitting upright. Hold the trainer with your hand on the E-Unit (black part on the main body). Make sure that the openings near the wheels are not obstructed. Now place the trainer in your mouth so that your lips cover the outer shield of the mouthpiece to make a seal. Look straight forward, looking down can cause more salivating.

Hard respiratory training can cause dizziness, we recommend that you stay in your position after training, and breath normally and slowly for a minimum 1-2 minute before raising.

Always remove the E-unit before cleaning with water or other liquids! After each training we recommend that you wash the device in warm water, shake off excess water and dry with a clean towel. Once a week, remover the mouthpiece from the device to be able to clean it better. Use a mild disinfectant solution instead of water. The disinfectant solution used must be intended for use on equipment that comes into contact with the mouth, such as that used for baby bottles. If in doubt, ask your pharmacist. After, hold the Breathing Trainer under running water, allowing it to run through. Shake off excess water and dry with a clean towel.

Issues with the Airofit breathing trainer

You should make sure that the Bluetooth on your phone is turned ON. Then, the Airofit trainer should be connected. If your trainer still cannot connect, try to restart your Bluetooth. (Turn it on and off) If it does not help, another reason might be that the battery level of your Airofit trainer might is too low or that you have multiple Airofit breathing trainers turned on in the same room. Charge your trainer and try to connect again.

Do not push the button after the connection has happened. Do not leave the app while using the trainer. Do not move the Airofit breathing trainer more than 5 meters away from the smartphone that the trainer is connected to.

You will find the charging plug inside the removable E-unit. Insert your Micro USB cable to charge your Airofit trainer. If the light on the button is blinking green you have inserted the cable correctly and your Airofit is charging. Once fully charged, the button will light green.

Check if you have inserted your cable correctly and if your cable works with other electric devices. You should also probe if your socket works for other electric appliances.

Yes, of course. Just send us an email at and we will take care of your order.
