Importance of IAQ
- On average, we spend more than 70% of our time indoors. Maintaining good IAQ helps protect our health.
- A polluted indoor environment can cause discomfort, including headaches, eye irritation, breathing difficulties, skin allergies, nausea and fatigue. In particular, children, the elderly and those with respiratory or heart disease are more susceptible to indoor air pollution.
- Good IAQ can benefit your company’s performance by improving staff productivity and reducing absenteeism.
- Short-term effects after exposure to high levels of indoor air pollutants:
- sore throat
- eye irritation
- nose irritation
- Long-term effects after prolonged exposure (up to years) to indoor air pollutants at high levels:
- respiratory diseases
- heart disease
