1. Start at the source of the problem

Wherever possible eliminate the source of the problem. You could be compromising the quality of your Indoor air in various ways:
- Combustion – ventilate where possible when cooking; know the impact of combusting candles, wood and gas in fireplaces and make an informed decision
- Materials and chemicals used in soft furnishings, fabrics, decoration and cleaning, carpets can breed allergens, dust and bacteria ~ choose materials and products wisely!
- Scented products: they come at a price, they emit volatile compounds; think carefully about personal grooming products too perfume, deodorants, nail polish and hairspray and ventilate, ventilate, ventilate!
