Outdoor pollution is an issue recognized by
most people. But how often do we consider the quality of the air
we breathe in our own homes. Indoor air can contain high levels
of carbon dioxide or be permeated by offensive body and food odours.
Due to security and heating considerations often doors and windows
are kept closed, so natural ventilation may not be adequate. Concerns
about unhealthy homes are very prevalent these days.
Fresh air is essential for our wellbeing. Allergies,
headaches and general discomforts are all associated with, if not
primarily caused by inadequate ventilation. Furthermore, interior
condensation causes long term damage to building materials.
