Indoor Air Quality

Eliminate sources of pollution by sealing off insulation, adjusting gas appliances to emit less leakage, ridding your home of chemicals and tobacco smoke, etc.
Increase ventilation by opening windows and doors, turning on exhaust fans in bathrooms and kitchens and adding mechanical devices where necessary.
Maintain extra ventilation while painting, using chemicals, cooking with unvented gas stoves, smoking, etc.
Increase mechanical ventilation rate by installing heat recovery ventilators or air-to-air heat exchangers. They draw outside air into the home and conserve energy by recovering the heat from the air that is exhausted to the outdoors.
Have a professional check your chimney, non-electric furnace, water heater, stove and other appliances regularly.
Make sure you burn the correct kind of wood and have good ventilation for fireplaces and wood burning stoves.
Check product labeling to make sure you have the safest products possible for cleaning, personal care, etc.
