27 September 2011 – Allergic reactions such as hay fever are claimed to be reduced by a new home ventilation design system developed by Ventis.

Designed and manufactured in Australia, the heating and cooling system takes air out of the roof space of a house, propels it through hospital grade filters, eliminating dust, pollens and other allergens, and pushes the fresh, clean air through the home.

On average, the system halves the energy bills of its customers with running costs about $5 a month, according to a statement from Ventis.
