Simply inhale deeply through your nose and exhale slowly and steadily through the AirZa mouthpiece. As you breathe out, the LED lights will illuminate from bottom to top — the higher the lights climb, the more effective your training session. Aim for a full, controlled exhale to reach the upper LED levels for best results.

Yes. AirZa features a modern USB-C charging port. Simply connect it to any USB-C cable (included in the box) to recharge. There are no disposable batteries required, making it environmentally friendly and always ready when you need it.

AirZa is designed to be suitable for a wide range of users, including seniors and those looking to support their respiratory wellness. The resistance-based breathing training is gentle and progressive. However, if you have a diagnosed respiratory condition, we recommend speaking with your healthcare provider before starting any new breathing exercise program.

The mouthpiece disassembles easily from the main body — no tools required. Remove it, rinse it under warm water, and allow it to dry fully before reassembling. Regular cleaning after each session is recommended to maintain hygiene.
