Frequently Asked Questions

Product Information

Airofit is a respiratory training system that improves athletes’ performance through tested breathing exercises. Whether you’re running, cycling, swimming or simply want overall better wellbeing; an improved respiratory system will benefit you. The best part – it will only take 10 minutes a day as Airofit is designed to be used separately from other physical activity.

The Airofit Breathing Trainer contains resistance wheels that provide adjustable restricted airflow. This resistance causes fatigue in your breathing muscles which is then compensated by muscle tissue growth, making your respiratory muscles stronger, faster and more efficient.

Airofit pairs with your smartphone, which gives you live feedback, guidance and the ability to track your progress. The mobile app consists of various training programs that target different areas of your breathing like Respiratory strength, Vital capacity, and Anaerobic threshold.

Airofit is designed to be used separately from any other physical activity. This means that you can use Airofit in any free moment – before bed, at work, after a gym session or whatever suits you best.

Training is done with your smartphone in front of you, as the app will guide you through every exercise via live feedback and data visualization.

Airofit is the first and only truly smart breathing trainer on the market. We know that one size does not fit all, therefore all Airofit training programs are tailored to YOU – we take into consideration your age, size, gender, and preference. Airofit also measures your vital lung capacity and breathing muscle strength. We take all that data as a baseline for your training and enable you to start and progress through your training correctly.

Airofit is also the only breathing trainer that goes beyond simple respiratory muscle training (RMT). We also address other aspects of breathing, like Respiratory strength, Vital capacity, Anaerobic threshold, and relaxation. We ensure that you can train harder, recover faster and most importantly – perform better.

Airofit is based on countless research within the respiratory training area. Refer to our Sciencesection to see the most relevant research papers.

Airofit has also been tested by an international Medtech company AMBU. After testing Airofit on 68 healthy individuals, the group training on the highest resistance settings showed an average performance improvement of 15% in a standard Cooper running test.

The price includes an Airofit Breathing Trainer and the mobile application with all future updates, which consists of training programs and sessions developed by experts. There are no hidden or additional monthly costs!

Airofit packaging also includes a quick guide and a charging cable.

When developed by AMBU, Airofit was originally designed as an asthma and COPD aid. Respiratory training is known to help with asthma symptoms.

In asthmatics, variety in tidal volumes is very common – their breathing muscles are working far from the optimal capacity. This makes them inactive and results in dyspnea/shortness of breath. This becomes most obvious during exercise, so you waste even more energy on breathing alone.

We are working with several asthmatics and their feedback is great – from easier asthma medication inhalation to lack of symptoms altogether. However, there are many different types and degrees of Asthma, so we strongly recommend you first consult with your doctor about respiratory training.

There is no age limitation to using Airofit. However, the mobile app does not let you register if you are under 13. This is because your results are measured compared to an average of an individual the same age – there is simply no quantitative respiratory data on children below 13. That being said, you can still use Airofit and all its features if you’re younger, but the data will be compared to a 13-year-old.

If you are under 15, we strongly advise training with adult supervision.

We recommend that you start training 2×5 minutes every day. We have found that 2×10 minutes per day is the optimal training schedule, but you should gradually work your way up to it.

Your breathing muscles are just another muscle group. You should always ‘listen’ to your body. If the training gets too intense, take a break.

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 blow through the device to remove water that might still be inside the device. Dry fully with a clean towel.

Once a week, remover the mouthpiece from the device to be able to clean it better. You can 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, dry through, and dry with a clean towel.

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.

Respiratory training is like all other forms of training, you need to train it all, but some training sessions are more specific. Therefore, we have put them into programs. You don’t need to finish a program to start another, but you can switch between them. Also, it is a good idea to mix your program training with single sessions from the single exercises’ menu.

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.
