Why is Indoor Air Quality Important?
People spend 90% of their time indoors and indoor air can be 2 to 5 times more polluted than outdoor air. The EPA (Environmental Protection Agency) has indoor air quality ranked as one of the top 5 environmental dangers. It is linked to severe asthma and allergy development in children and to heart problems and lung cancer in children and adults.
Symptoms depend on the particular contaminant and are sometimes mistaken for allergies, stress, colds or the flu.
- Some of the symptoms of poor indoor air quality are:
- Watery eyes
- Upper respiratory congestion
- Nasal congestion
- Nose bleeds
- Sore throat
Poor indoor air quality can contribute to the development of or exasperate these problems:
- Lung cancer
- Chronic lung diseases
- Heart disease
- Hearing loss
Indoor air quality is affected by anything that releases gas or particles. The most common causes of poor indoor air quality are:
Inadequate ventilation – contaminated air can’t get out, fresh air can’t get in
Unmaintained heating and air conditioning systems
Dampness due to floods, leaks or high humidity – creates mold and bacteria
Occupant activities – cleaning, personal care, construction, smoking
Combustion – burning of some form of fuel
Old/outdated building materials – asbestos, wood treated with formaldehyde
What can you do to improve the air quality in your home?
Use proper ventilation around fuel burning appliances like furnaces, fireplaces, ranges and heaters
