AirPhysio reviewQuestions to ask before buying an OPEP device

How OPEP works

OPEP stands for oscillating positive expiratory pressure. It combines resistance as you breathe out with oscillations that can help move mucus from the airways. Kent Community Health NHS Foundation Trust recommends using a device with advice from a respiratory physiotherapist and the manufacturer's instructions.

That guidance explains the purpose of OPEP. It isn't an endorsement of AirPhysio or proof of every claim on the product's sales page. Choosing a particular model still calls for advice about your needs.

Check suitability before buying

Read the manufacturer's user guide and discuss it with your clinician. Its warnings include untreated pneumothorax, tuberculosis, oesophageal surgery, right-sided heart failure and middle-ear problems. Read the complete current instructions for the model you receive; this list isn't a personal screening checklist.

AirPhysio should not replace prescribed medication or an inhaler. A drug-free design doesn't make a device suitable for everyone, and an advertisement can't tell you which resistance level you need.

Ask your respiratory physiotherapist which model they recommend and whether they can demonstrate the technique. It's also worth asking how you'll judge whether it's helping. Those answers matter more than the discount on the order page.

Cleaning is part of the routine

The manufacturer calls for cleaning after each session. Use the instructions supplied with your device for taking it apart, cleaning it and putting it back together. Instructions for another OPEP model may differ. Keep small removable parts away from unsupervised children.

Portability is convenient, but think about the daily routine too. You'll need to handle the device comfortably and have time and space to clean it. If taking it apart looks difficult, raise that with your clinician before ordering.

How to compare your options

Ask about devices available through your care provider as well as retail options. Consider how easy each is to handle and clean, whether replacement parts are available, and what help you'll get with the technique.

General OPEP guidance doesn't establish that AirPhysio is better than other devices or that benefits will arrive on the timetable in an advertisement. The right choice should fit the plan you've discussed with your clinician.

Ordering and returns

The merchant advertises a 45-day money-back guarantee. The complete return conditions and final delivered price still need checking. In particular, confirm whether an opened device can be returned.

Check the model and shipping country before paying. Availability varies by country, so an English-language page doesn't guarantee delivery to your address.

Our verdict

AirPhysio is worth discussing with a respiratory physiotherapist if you're considering an OPEP device. Its portable, battery-free format is convenient, and the manufacturer provides use and cleaning guidance.

Our editorial rating is 4/5. It assesses the buying information, not clinical effectiveness: general OPEP evidence alone can't establish what this model will do for you. Buy only after confirming that the model and routine fit your care plan.
