Ban smoking
The number one way to combat indoor air pollution is to never let anyone smoke in your home. It has been said that the second hand smoke can cause cancer. By banning smoking in the house you always have a clean smelling home and there are no harmful toxins floating around in your home.

Grow plants indoors:
Live plants around your home act as natural air filters, and some plants are particularly effective absorbers of harmful pollutants emitted from carpets, furniture, and electronic equipment. So clean your indoor air and “green” your living space by filling your home with Aloes, spider plants, Boston ferns, rubber plants, and palm trees.

For those who are very conscience regarding the air around them, the following additional detectors can be purchased.

Install a carbon monoxide detector:
Carbon monoxide is an odourless gas and exposure to it can be deadly. To prevent carbon monoxide poisoning, pick-up a detector at your local hardware store.

Check for radon:
Radon is a radioactive gas that is naturally present in soil, and it can enter your home through cracks in your foundation. Radon is also a cause of lung cancer. Radon test kits are available at most hardware stores.
