Humans on average breathe over 11,000 litres of air each day. We spend 90 per cent of our time indoors; be it in our homes, places of work, schools, or health and fitness centres, where the levels of pollutants and allergens can be 100 times higher than already dangerously polluted outdoor air. Breathing polluted air makes us sick and is a root cause of many fatal diseases. Protect yourself and your family with Therapy Air® iOn - the leading five level air purification system for healthy air.
