A key to a healthy, comfortable home is ventilation. The use of exhaust fans, ceiling fans, and bath fans can keep a home's indoor air quality from becoming too humid, dry, stale, dusty, or mildew ridden. Although you can control humidity with a dehumidifier and dry air with a humidifier, those alone don't necessarily provide good ventilation. With the use of heat exchangers, for instance, you can pump out the old, stale air and replenish it with new, clean, crisp air. The best part is that this air is run through a filtering system to draw out most of the pollutants.
Ventilation comes in many forms throughout the home. The range hood in your home draws both heat and moisture away from the stove. A wood burning stove, corn burner, or fireplace needs ventilation to remove the toxic smoke from the chamber. Don't forget about water heaters and furnaces that also require exhaust removal to keep the air clean and safe. All of the units use oxygen when they burn, so it's essential to replenish the supply with outside air.
Probably the most important thing to keep in mind is you and your family's health. Fresh air in your home provides a healthy environment to live in. It reduces the chance of being infected by viruses, mold problems, respiratory problems, smoke and carbon monoxide inhalation and water damage to your home.
Besides livable areas, garages and attic spaces shouldn't be overlooked. Exhaust from cars and trucks is toxic. Garages should always have good ventilation when a vehicle is running. Nevr sit inside your car in a car while it is running with the garage door closed. Attics can benifit from ventilation with the use of a roof vent, especially a power ventilation system. These electric fan units have a bult-in thermostat to automatically turn on the fan when the temperture reaches the preset temperature.
