As energy efficiency has become much more important, We have insulated, blocked chimneys, improved glazing and gone out of our way to prevent outside fresh air from coming inside. This has led to indoor air quality (IAQ) being affected.
Factors affecting indoor air quality
- Volatile Organic Compounds (VOC’s) created from the use of aerosols and cleaning agents. Also chemicals found in furniture and carpets.
- Humidity which is created from living our daily lives of cooking, showering, washing and ironing.
- Toxic mould spores which can be found in high concentrations
- Odours from cooking and household pets.
- Allergens from house dust mites.
- Carbon dioxide from household appliances and people.
- Hazardous carcinogenic chemicals from bleach, cleaning products and fabric softener.
Children, asthma sufferers and the elderly are especially sensitive to indoor air pollution, but other effects on health may appear years later, after continuous exposure.
