Mechanical ventilation is critical to the health of the home. In the same way that your lungs supply your body with the oxygen you need to thrive while dispelling harmful carbon monoxide, a well-designed ventilation system provides indoor air quality that is so vital to a well-functioning living space.
The best ventilation system can dilute or eliminate pollutants, control mold and mildew and filter air to remove unwanted particulates from a home. Pollutants such as smoke, dust, heat, metals, humidity and CO2 accumulate in a poorly vented building. Good ventilation means providing good indoor air quality. A well-designed ventilation system also saves energy, controls moisture and improves the durability of the home.
Chemical pollutants such as pesticides, metals (such as lead, mercury, cadmium and arsenic), minerals, asbestos, old paint and treated lumber lurk in many home products and can cause health issues. Biological pollutants, to some degree, are found in all homes. These include things like mold, mildew, pollen, dust mites, pet dander, viruses and bacteria.
Pollutants stack up in places like bathrooms or basements, and can even hide out in wall cavities. Accumulation of pollutants results in hazardous health effects for the occupants, as well as structural damage to the building. As people spend more time in their homes, the rise in the rate of asthma and respiratory illnesses has also increased.
Unfortunately, indoor pollutants are virtually impossible to eliminate completely. Because of this fact, mechanical ventilation is necessary to guarantee good indoor air quality. By installing high performance vent fans, you can efficiently— and using sensor controls, automatically—remove any stale, moist, polluted air and replace it with fresh outside air.
