Comparing POWERbreathe Classic, Plus and K-Series

POWERbreathe mechanical and electronic IMT devices.

We’re often asked what the difference is between the various series of POWERbreathe models, so we thought we’d help by writing a quick overview of each series.

Mechanical Classic and Plus vs Electronic K-Series

The models in the two mechanical series’ of POWERbreathe require their variable load training to be adjusted mechanically.
The models in the electronic series of POWERbreathe feature an electronically controlled resistance valve which automatically provides the appropriate training load.

The Mechanical Series

POWERbreathe Classic was the first mechanical POWERbreathe series to be developed. It is an entry level series and ideal for those new to breathing training.

POWERbreathe Plus was the second mechanical POWERbreathe series to be developed. It has a more contemporary and ergonomic design than the Classic which results in a 65% improvement in airflow dynamic and therefore a more comfortable and efficient user experience.

Mechanical Series Models

Each series (POWERbreathe Classic and POWERbreathe Plus) has three models available within it, so there is a model to suit everyone, whatever level of fitness or breathing strength.

  • Level 1 (LR) – Entry level for new users and those with breathing problems (e.g. asthma).
  • Level 2 (MR) – For those who are moderate to very fit.
  • Level 3 (HR) – Only for those who have reached the maximum loading on Level 2.

What do the different colours signify?

When the first three POWERbreathe Classic units were manufactured colours were used for ease of identification: green for Level 1 (LR); blue for Level 2 (MR); red for Level 3 (HR).

The same three colours were then used for the second POWERbreathe series: POWERbreathe Plus. Later in the development of the POWERbreathe Plus series limited edition colours were introduced (e.g. Amethyst) then later still special edition colours: Special Edition Black and Special Edition Pink.

The Electronic K-Series

The POWERbreathe K-Series is the third POWERbreathe series to be developed and is the world’s first intelligent digital breathing training device. It is the only advanced electronic series with training feedback. Because it uses auto-optimising Inspiratory Muscle Training technology, it takes the guesswork out of training. Unlike the mechanical series’, the electronic K-Series offers advanced, adaptable and personalised respiratory coaching.

Electronic Series Models

  • POWERbreathe K1 – Entry level with basic essential features.
  • POWERbreathe K2 – Intermediate model with more advanced features. 
  • POWERbreathe K3 – Advanced model with yet more advanced features plus graphical history and warm-up/cool-down modes. 
  • POWERbreathe K4 with Breathe-Link Software – Elite training, testing and monitoring for individuals.
  • POWERbreathe K5 with Breathe-Link Software – Elite training, testing and monitoring for individuals, personal trainers, groups and team coaching environment as the K5 Breathe-Link software offers personalised breathing training sessions.

  1. Good evening
    Is PowerBreathe Plus 2 the same as PowerBreathe Plus or they differ somehow / how ?
    I would like to buy one for fitness / free diving / swimming
    Do you also know if it could provide the same benefits as iQORO ( good for acid reflux ) ?

    Many thanks

    • Hello Claudio and thank you for your enquiry. Regarding the use of inspiratory muscle training for acid reflux, I can point in the direction of a research paper that found IMT decreased heartburn and regurgitation scores and “improved esophagogastric junction pressure, reduced gastroesophageal reflux proximal progression, and reduced gastroesophageal reflux disease symptoms.” In regard to the Plus models, I’m afraid I’m uncertain as to what you mean here, as we only have one Plus series. I’m wondering if you mean the Classic series (which was developed first) and then the Plus (which was developed later from subsequent research and development). The precision calibrated spring is the same in the light resistance Classic model, as it is the light resistance Plus model. The precision calibrated spring is the same in the medium resistance Classic model as it is in the medium resistance Plus model (and ditto for the heavy resistance Classic and Plus). The Plus is made from a different material, has a better design to allow more airflow, and as it was developed later than the Classic, has a higher price. So it may be that you just decide on your budget: £29.99 for a Classic or £49.99 for a Plus. Next, is which model to choose from. If you’re already quite fit (and it sounds as though you are), we would suggest the Medium Resistance model (in the Classic or Plus), with one proviso…. Because you have a medical condition we always recommend you speak to your GP first before trying any new form of exercise. Hope that helps Claudio.
