Trysafe filters are only intended for single-use.

The body is Polypropylene and inside the filter paper is an electrostatic filter material.

POWERbreathe doesn’t increase VO2 but a result of inspiratory muscle training is that it enables greater blood flow to your other working muscles (legs and arms) so that you can exercise for longer without feeling so fatigued. When your breathing muscles get tired, they can ‘steal’ blood from other exercising limbs to supplement their work, so improving the efficiency of the lungs has the knock-on effect of increasing the performance of your other working muscle groups.

PVC (Not made with natural rubber latex or and phthalates). All the mouthpieces for the POWERbreathe units are BPA (Bisphenol-A) free. Please see detail below: 

  • POWERbreathe K-Series mouthpiece: – Material Name: NonP650 (no Pthalate or Bisphenol-A plasticisers)
  • POWERbreathe Classic/Plus mouthpiece: – Material Name: Colorite 6811G-015 (uses DOP plasticiser, no Bisphenol-A)

Please note: Other parts of the POWERbreathe products do contain Bispehnol-A but these parts are not in direct contact with the mouth.

The mechanical POWERbreathe Classic and Plus breathing muscle trainers create the resistance to breathing by using a calibrated spring loaded valve. The training is very similar to lifting weights in the gym. The resistance to breathing in, (weight you are lifting), is created using the spring loaded valve, so when you generate enough power with your inspiratory muscles, the valve opens at the “pressure threshold”, hence the scientific term, ‘pressure threshold’ trainer. This means that your breath in will ‘cut-off’ as you reach that threshold.

The K-Series is an electronically controlled ‘tapered flow’ resistance breathing muscle training device that uses a computer controlled rotary valve to create the resistance to breathing.

This means that the resistance to breathing is not fixed at the same level throughout the breath (like a pressure threshold device), because it automatically reduces the resistance as you progress through your breath, to match your declining muscle strength.

Basically, you will be able to perform a longer inspiration and use a wider range of breathing muscles, because you can breathe in after the point where the fixed resistance of a pressure threshold valve would have closed.

The result? Higher flow and higher tidal volumes can be achieved which will maximise your training. Basically, it makes the training feel easier but you’re actually working harder and will therefore achieve better results.

We would strongly recommend you consult with your GP or medical practitioner as you have a medical condition, as we would with anyone that has a medical condition. As the POWERbreathe Medic is available for prescription in the UK, your medical practitioner should be familiar with POWERbreathe inspiratory muscle training and be best to advise you.

We’d recommend speaking to your GP about this because a hernia may be exacerbated by POWERbreathe training.

There are no safety reasons for preventing young children (above 7 years of age) from using POWERbreathe. However the following factors may affect their ability to use the device effectively: 

  • They must be able to fit the mouthpiece in their mouth. The POWERbreathe Plus mouthpiece is smaller and therefore more suited to children 
  • They must be old enough to understand how to effectively perform the breathing exercises 
  • They must have the motivation themselves or the parental encouragement to ensure that they continue to perform the exercises 
  • They should only use POWERbreathe under the supervision of an adult

Inspiratory muscle training has been most widely used in patients with COPD. The rationale is particularly strong in this patient group, as they have primary weakness of their inspiratory muscles. 

Neck problems are very rare when using POWERbreathe but have been known to occur when breathing against very heavy loads and in people with a history of neck injury e.g. whiplash. Our advice is as follows: 

  • In order to warm-up before training with POWERbreathe, perform a warm-up session mode; alternatively perform 10 breaths set the load to 80% of you normal resistance (e.g. if you normally train at level 5, set the POWERbreathe to level 4). Perform a set of 30 breaths at this level prior to training at your normal intensity. This should help warm-up the muscles in the neck and chest 
  • Now perform your normal set of 30 breaths – try to breathe from the chest and diaphragm, keeping your neck as relaxed as possible. If you are still experiencing discomfort, reduce the load slightly – it is important to take controlled breath as well as pushing yourself. Remember that the same principles apply to POWERbreathe as with any other resistance training 
  • If you perform uncontrolled movements at high intensities then you may be increasing the risk of muscle strain. If the pain continues, we would advise that you consult your doctor or chiropractor as the problem is likely to be due a slight displacement of a vertebrae (of the kind experienced when one gets a ‘crick’ in the neck’) rather than to a muscle strain The load results on the POWERbreathe unit and pressure value on the Breathe-Link IMT suite do not correlate.

Simply remove the mouthpiece and handle cover and then drop the 3 pieces (mouthpiece, handle cover and body) into water with cleansing solution. You could always just drop the whole thing in complete, but it would clean the POWERbreathe more thoroughly if you dismantled it into these 3 parts.

Cold water sterilisation only.

Not suitable for sterilisation by boiling, steam, microwave or oven.


POWERbreathe Cleansing tablets are recommended. You can also use a solution that is intended for use on equipment that comes into contact with the mouth, such as that used for babies’ bottles. If in doubt, ask your pharmacist.

No, do not attempt to clean your POWERbreathe in any way other than instructed in your User Manual.

Definitely not because vinegar is a corrosive acid. We recommend using either POWERbreathe Cleansing Tablets, or a solution designed for cleansing infant feeding bottles.

No, do not attempt to clean your POWERbreathe in any way other than instructed in your User Manual.
