I feel fantastic!

I was reluctant to try something as simple as steam for my breathing issues, having had 43 years of poor breathing. But from the first use, I knew I had made the right choice with WellO2.

Thank you for a brilliant product!

As a professional vocalist, having had a couple bouts of sinusitis and doing some dusty house renovations for the past few months, I feel Wello2 not only cleanses my respiratory system, but is also strengthening it.

This resistance training strengthens the respiratory muscles, and the warm steam helps open and moisturise the airways.
