Frequently asked questions

What is Airofit and how does it work?

Airofit is a respiratory training system. The breathing trainer provides resistance on your breathing muscles, while the mobile app gives you live feedback and guidance through exercises, as well as, the ability to track your progress.

How is Airofit different from other breathing trainers?

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.

Can multiple people use the same device?

It is not recommended that people share the device, for two reasons: 

  1. The product is designed so that one user can reach their full potential, which requires training every day, 5-10 minutes twice a day. For this reason, it may complicate training if you are trying to share one device.
  2. For sanitary reasons, we cannot recommend that you share a device, as you cannot wash the whole device (you can wash the passive unit without the electronics and the mouthpiece), we cannot assure 100% that when you clean the device, all the bacteria will be gone. 

If you, however, decide to share the device, please make sure that you use different phones and different accounts, so your results don’t mix up 🙂

Is Airofit the same as altitude training?

Airofit does not work the same as altitude training. Airofit is a respiratory training system. The breathing trainer provides resistance on your breathing muscles, while the mobile app gives you live feedback and guidance through exercises, as well as, the ability to track your progress.

Just like any other muscle group, your respiratory muscles can become stronger, faster and more efficient, which directly correlates to a better O2, therefore improving your physical performance.

What is the difference between Airofit and an elevation mask?

In essence, elevation masks simply restrict airflow to your body while you are exercising, which is not only inefficient but also a bit dangerous. By training with an elevation mask that provides you with insufficient resistance, you lower the oxygen level, and raise the CO2 level in your blood. That is not the purpose of respiratory muscle training.

Training your respiratory muscles (as with Airofit) should be done separately, in a relaxed state and this will ensure that you actually work on strengthening your muscles. Also, Airofit will allow you to adjust the resistance to different levels, so that you can build up your strength just like you would by lifting weights with any other muscle training. On top of that, the Airofit breathing device, together with the mobile app, offers you live guidance through each session, live feedback and the ability to track your progress.

Can Airofit help if I have asthma and/or COPD?

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.

Would it help me? I am not an athlete.

The beauty of Airofit is that it can and should be used by anyone – from Olympic athletes to non-athletes who just want to become better versions of their current selves.

How do I know if Airofit is for me?

If you are unsure whether Airofit is for you, feel free to book a personal pre-purchase session. Here you are able to ask all about Respiratory Muscle Training, breathing techniques, and what makes Airofit the perfect tool to boost your performance and overall well-being.

How often should I train?

We recommend you train your breathing every day. Remember that it is not about training for a long period of time. 10-15 minutes a day is more than enough but consistency is key!

If you train daily, we do recommend you split your program into two and train twice a day. The best results are obtained when you complete two training sessions at different times of the day.

Does Airofit track HRV or Sleep?

No, it does not. However, you can integrate your Apple Health data to your Airofit app. To do so, you will need to go to open the Airofit app and go to Settings – Account – 3rd Party Apps – Apple Health.

Is there an age limit for using Airofit?

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. 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.

What is the difference between the PRO 1.0 and the PRO 2.0?

 The PRO 2.0 brings great new features and refinements:

:lungs: Advanced Lung test

Take the most comprehensive lung test in the world divided into 3 steps and get a super precise measurement of your accessible lung capacity, inhale and exhale strength.

:point_right: Improved guidance

Get detailed guidance on your breath training together with more accurate feedback on your performance to understand and practice different breathing patterns.

:chart_with_upwards_trend: More accurate results

Eliminate external factors from affecting your training and test results. Our new way of measuring your breath will ensure there’s minimal deviation in your training data.

:man_and_woman_holding_hands: Better peer comparison

Comparison with your peers and their breathing training performance has never been so accurate. Get the suggestions from our app and find out where you’re ahead of your peer group and where you should improve.

:zap:️ Optimized hardware

Enjoy your breathing training with compact and durable hardware. A newly designed e-unit and magnetic charging method will secure that your Airofit is saliva & splash resistant. Moreover, a long-lasting battery (4-7 days) ensures that you can train with Airofit anytime and anywhere.

What is the difference between the Active and the PRO?

The Pro will offer Bluetooth connectivity allowing for live program guidance, feedback, and progress tracking. The Active, is exact same as the Pro in terms of design, look and feel. However, the Active will not have Bluetooth connectivity, and thus you would not receive progression tracking or live feedback on how you are performing the training sessions.

I have an Active but I want the PRO, what do I do?

If you have any inquires on how to upgrade your Active to the PRO, please send us a message on support@airofit.com.

How do I take the lung test correctly?

Try to focus not necessarily on force, but on control. Make sure that you’re utilizing your diaphragm. This means making sure that you’re breathing through your belly and using those muscles as much as possible for both inspiratory and expiratory. 

Keep in mind your test results can vary if you take the test different times/ under different condition. For instance, your lung test results may differ if you have just eaten compared to when the stomach is empty. To learn more, please watch the following video: https://www.youtube.com/watch?v=RFnj6yK5SnA

How do I track my results?

Select the “Activity” icon on the navigation panel at the bottom of your screen. Here you can find your training progress and statistics.

What parameters are used in the app?

The parameters that are measured and presented in the app are your Vital lung capacity, Maximal inspiratory pressure, and Maximal Expiratory pressure at the given resistances.

The Airofit system contains pressure sensors and translates the pressure into vital capacity and peak pressure. This indicates the inspiratory and expiratory strength. In theory, it is created by algorithms, correlating pressure and flow into volume.

Will Airofit add more programs or sessions to the app in the future?

Yes! The app and its content will constantly be under development, and new training sessions and programs will be added.
