Research has shown that the quality of indoor air can be worse than that of outdoor air. Many homes are built or remodeled more tightly, without regard to the factors that assure fresh and healthy indoor air. Our homes today contain many furnishings, appliances and products that can affect indoor air quality.
Signs of indoor air quality problems include:
- Unusual and noticeable odors.
- Stale or stuffy air.
- Noticeable lack of air movement.
- Dirty or faulty central heating or air conditioning equipment.
- Damaged flue pipes or chimneys.
- Unvented combustion air sources for fossil fuel appliances.
- Excessive humidity.
- Presence of molds and mildew.
- Health reaction after remodeling, weatherizing, using new furniture, using household and hobby products, or moving into a new home.
- Feeling noticeably healthier outside.
Surprising Sources Of Indoor Air Pollution
Air fresheners may cause breathing difficulties and headaches for some people. In a study, nearly one-third of people with asthma said they had breathing problems when exposed to air fresheners. Tests by the Natural Resources Defense Council found that some air fresheners contain phthalates, a chemical linked to child developmental and hormonal issues. Instead, use natural herbs like rosemary, basil, or mint and good ventilation to freshen air.
Improperly installed or vented gas stoves can release harmful gases into your home. At low levels, carbon monoxide can cause fatigue. Higher concentrations can cause nausea, headaches, confusion, and even death. Nitrogen dioxide can cause respiratory problems — especially in children. Make sure burners are adjusted correctly so that flame tips are always blue. Vent the stove with a fan that blows outside.

When you bring freshly dry-cleaned clothes into your home, your family may be inhaling this potentially harmful chemical. Air dry-cleaned clothes in the garage for several days before wearing them or wash clothes the traditional way.
