The Airofit PRO 2.0 is the sweet spot for respiratory training. It provides the data-driven feedback loop of the Elite model at a more accessible price point. A must-have for serious swimmers.
Breathing is as crucial to your life as water is to your swimming.
You draw a breath thousands of times per day, yet how often do you actually stop and examine your vital breathing pattern?
Similarly, when training, you more than likely tend to focus on endurance and muscular strength. If you are a bit more seasoned athlete, you also hopefully include technique training and perhaps some mindset coaching.
But what about breathing?
If the end goal is to improve performance, then it stands to reason: the more efficiently you can breathe, the better you will perform.
This being a swimming advice blog, let's focus on breathing in terms of swim training.

It is no secret that having your head below the surface of the water for most of a swim practice or race causes huge oxygen efficiency issues. This is drastically detrimental to your performance.
Therefore, if you can be more efficient and effective with your breath, it will directly influence the way you swim and how you enjoy swimming in general.
Good news is that, like with everything else these days, there is an app for that :). So read on to learn more.
In the past, I have already mentioned that there are some useful breathing swim sets you can incorporate into your workouts to strengthen your lung skill set.
There is also the simple device called PowerBreathe which does a fine job. But to be honest, since there is no feedback loop, it gets a bit boring to use after a while.
Let me introduce you to the new kid on the block which brings breath training into the 21st century.
Meet the Airofit PRO 2.0.

The Airofit breathing device is simple in design, yet sophisticated enough to do what it was designed to do. In essence, it will become your training partner on your way to healthier and stronger lungs.
I got my hands on the PRO 2.0 model and have been giving it a whirl to check if the marketing claims are up to par with the actual performance gains.
To get rid of the suspense... I like it.
It does exactly as promised. After just a few sessions, I could feel more aware of my breathing and learned to utilize my diaphragm better.
It feels as if the device helps you open up your lungs to absorb more air, as well as strengthens the diaphragm muscles to help you inhale and exhale.
When you order the actual breathing device, it will come in a professional-looking box with plenty of instructions.

In addition to the basic Airofit setup, you will also receive an extra mouthpiece and a magnetic charging cable to keep your tech running. The new PRO 2.0 is splash-resistant, making it much more durable for a swimmer's lifestyle than the previous generation.

After you have installed the Airofit app from the app store of your choice and your device is connected to your phone via Bluetooth, you are prompted to choose whether your focus area is Sport or General Wellbeing.
The next step is to select your preferred sport. Swimming, right? :)
At this stage you are presented with a generalized program which lasts 28 days. I suggest you start here to get familiar with how the device works and what it can do for you.

Before you begin, you will be asked to perform a Lung Test to establish your base. This is unique to the PRO models.
Don't worry if your stats are not what you expected them to be. You will perform similar lung tests throughout your training, so there are plenty of opportunities to see your progress.
There are 3 key metrics you will receive from the lung test:

For some reason, I did really well on the lung capacity and inspiratory pressure, but my expiratory pressure was initially lousy.
The Results: After just 2 months of training, I was able to increase my lung capacity from 6 Liters to over 8 Liters.

Airofit is very easy to use and the Danish team behind it put together an intuitive mobile application.
After you connect the device, you are prompted to choose your focus. I suggest starting with the generalized 28-day program to get familiar with how the device works.
After setting your baseline, you will perform 2 routine breathing exercises every day.

All it takes is just a few minutes per day.
From my experience, it is better to perform your breath training at the same time every day (e.g., morning). Your focus varies throughout the day, so sticking to a schedule ensures consistent data.

When you are done with the 28-day training program or if you need more training, the Airofit app comes with plenty of other programs to select from, so you can breathe your way to success as much as you wish.


As much as I like the device, I did run into a few issues.
1. Motivation: After the initial excitement wore off, it was hard to keep my motivation up. Even though it's only 10 minutes, breathing into a device is an "odd" exercise. The Premium subscription helps here by letting you compare results with peers, which adds a competitive element.

2. App Focus: You have to keep the app open on your screen. If you put it in the background to check an email, the voice guidance stops. It would be nice to be able to multitask during the easier sessions.
3. Cleaning: While breathing, there is naturally saliva build-up in the device. Luckily, cleaning the PRO 2.0 is simple. Just pop the E-Unit (electronics) off and wash the rest under running water.
Airofit now offers four different models. Which one is right for you?
1. Airofit ELITE ($349) - The "Most Advanced" The new top-tier model for data obsessives.
2. Airofit PRO 2.0 ($199) - The "Sweet Spot" This is the model I reviewed and arguably the best value for most swimmers.
3. Airofit Essential ($174) - "Great Value" A simplified connected version.
4. Airofit Active ($129) - The Analog Option

If the price of the Airofit ecosystem is a dealbreaker, or if you just want simple mechanical resistance without the app data and feedback, there are analog options available.
These devices won't track your progress, guide your sessions, or measure your lung capacity, but they do provide the basic mechanical resistance needed to strengthen your breathing muscles for a fraction of the cost.

Finally, as I mentioned earlier, there is an app that is used with the Airofit breathing device, and you can either use it as a free user or try the Premium membership for 30 days free.
If you decide to go the membership route, here is what you get:

No matter who you are or how you train, improving your lungs should be incorporated into your daily life. Do not neglect it.
I am lazy by nature. If someone tells me "train harder and you will improve," I can already feel my brain complaining.
That is why I like to train smarter, by improving technique and focusing on often forgotten aspects like breathing.
Airofit PRO 2.0 provides the data and the structure to make that happen. If you can stick to the routine, the results are undeniable.
So go out there, learn to breathe better, and swim smarter, not harder :).
Airofit is a smart breathing trainer that measures your lung function and provides resistance training for your respiratory muscles via a mobile app.
Yes. By strengthening the diaphragm and intercostal muscles, Airofit allows you to access more of your 'accessible lung capacity.' In my testing, I went from 6L to over 8L in two months.
The ELITE is the top-tier model with a 14-day battery life, a positional sensor to correct posture, and more training data. The PRO 2.0 has a 7-day battery and tracks all essential metrics but lacks the posture sensor.
The recommended protocol is just 5-10 minutes a day. The app guides you through specific programs (like Anaerobic Threshold or Vitality) to ensure consistency.
Yes. The PRO 2.0 is splash-resistant. You simply pop off the electronic unit (E-Unit) and wash the mouthpiece and resistance unit under warm water.
