Indoor Air Quality

Clean air is essential for good health, and this is especially true when it comes to indoor air. We spend close to 90% of our time inside – at home, at work, and in recreational environments. Most people, however, are unaware of the effects that poor indoor air quality can have on their health.

Concern over indoor air quality has come about as a result of rising pollution, tighter and more energy efficient homes, increases in personal sensitivities, and people spending more time at home, especially if an individual has a home office. Studies have shown that the air we breathe indoors is often many times more polluted than outdoor air. The World Health Organization says that 30% of homes today contain enough indoor pollutants to cause health effects and the U.S. Environmental Protection Agency calls indoor air pollution one of today’s top four environmental threats.

Good air quality is defined as indoor air at a constant temperature delivered without drafts, containing the correct balance between oxygen and carbon dioxide, having the correct relative humidity, and absence of odours, airborne particles, moulds and harmful gases.

The best way to deal with an indoor air quality problem is to eliminate the source as much as possible. This could include reducing the amount of chemical products used in the home, removing an old dusty carpet or eliminating mould in an infected area. If indoor air quality problems persist then the application of mechanical systems such as air cleaners, humidifiers and fresh air systems could be considered.
