Behind WellO2 is a team of trusted doctors, professors, and elite trainers who understand how vital breathing is. They work closely with us to deliver safe, effective, and research-backed results.

Breathing Shouldn’t Get Harder With Age

As we get older, our breathing muscles naturally become less active if they aren't regularly exercised. For many, everyday activities like climbing stairs, walking uphill, or even having a conversation can begin to feel more demanding than they used to.

The good news is that breathing muscles can be trained. Regular breathing exercises can help you maintain breathing muscle strength as part of an active, healthy lifestyle.

Many people include WellO2 in their daily routine for:

  • Maintaining breathing muscle strength
  • Daily breathing exercises
  • Warm steam during breathing exercises
  • Use in dry indoor environments
  • Voice training and speaking professionals
  • Trouble falling asleep or snoring

Build stronger breathing habits at any age.

Immediately easier to breathe and +20% more breathing power in just one month!

    Warm steam helps open and moisturise the airways during breathing exercises.

  • Exhale with resistance

    Gentle expiratory resistance helps open the airways while strengthening the expiratory muscles.

Breathe Better. Train Smarter. Feel the Difference.

The WellO2 Steam Breathing Trainer includes three coloured mouthpieces for comfortable steam inhalation through the mouth. A nasal mask is also included for effective steam breathing through the nose.

Why use a Nasal Mask?

Breathing through the nose naturally filters, warms, and humidifies the air. The WellO2 nasal mask is designed to direct warm steam through the nasal passages during breathing exercises.

Using the nasal mask helps you:

  • Supports Nasal Breathing – Directs warm steam through the nasal passages during breathing exercises.
  • Helps Open the Nasal Passages – Exhaling through the nose with gentle resistance helps open the nasal passages as part of your breathing exercises.
  • Strengthens the Upper Airway – Regular training helps tone and support the nasopharyngeal muscles.
  • Encourages Regular Nasal Breathing – Supports incorporating nasal breathing into your daily breathing exercise routine.
