Indoor Air Quality

One of the things that people seem to take for granted these days is the indoor air quality. When people look for a house, apartment or office space, IAQ is the least of their concerns. It is only when they start to get sick when they consider the importance of air quality. Polluted air can lead to irritation of the nose, throat, and eyes. Eyes will be irritated, and people tend to cough, wheeze, or have difficulty in breathing. Existing heart and lung problems will worsen, and allergies will be developed.

Biological Pollutants Mould spores (microscopic particles) are found everywhere. They are released into the atmosphere by damp spots on walls, window frames or even decaying food. They can be common in houses which have little or no ventilation. Pollen can be a pollutant factor in your home, usually brought in from outside either by leaving your windows open in high pollen seasons or even by walking around the house in shoes you have worn outside. Dander is tiny particles, which come from feathers, skin, or hair, that may cause allergies.
