Active Ionisation air cleaning technology combined with advance airflow engineering. This technology is far more efficient than traditional air filters such as HEPA as these impede airflow. Evergen’s technology does not impede air flow, so are very low power consumption and there are no filters to change. PureAire systems can remove a variety of pollutants and odours

Developed at : Evergen Systems

Evergen : Worldwide license Evergen Trade mark
Patented : In process
Status : In production now, Systems built to ISO 16890 standards (the very latest standard for air quality)


This is a highly innovative method for cleaning a polluted airstream using a reactive species of ozone. Adding ozone to a reaction surface above 40°C counters the pollution. In contrast to current technologies, the reaction surface is not a catalyst. It is therefore possible to use materials already known in the ventilation and construction industries.
