The purpose of ventilating a home is to maintain a healthy and safe living environment.

New insulation techniques such as “air sealing” homes often result in stale and polluted indoor air.

When there is little ventilation in a home, pollutant levels can increase.

Why Ventilate

The purpose of ventilating a home is to maintain a healthy and safe living environment by supplying fresh air while at the same time removing stale and polluted air. In some parts of the country and during certain times of the year, ventilation can also help maintain proper humidity levels of 30 to 50 percent.

The reason for the buildup of indoor pollution in today’s homes is a direct result of our efforts to conserve energy and save money. As the techniques and materials used to insulate and “air seal” homes have improved over the past 30 years, the result is stale and polluted air.

Common sources of indoor airborne contaminants include:

  • Chemicals used in the construction or renovation of buildings
  • Appliances that burn gas
  • Wood-burning stoves and fireplaces
  • Pets
  • Off-gassing of furniture, cabinets, flooring, and countertops
  • Infiltration of ozone, pollen, and molds from the outside
  • People
  • Cleaning supplies

The rate at which outdoor air replaces indoor air is described as the air exchange rate. When there is little ventilation, whether natural or mechanical, the air exchange rate is low and pollutant levels can increase.

Ultra-Aire whole home ventilating dehumidifiers provide an effective and efficient exchange of stale indoor air for healthy, fresh, outdoor air.

Ultra-Aire Whole House Ventilating Dehumidifiers 

According to the Environmental Protection Agency, “Unless they are built with means of mechanical ventilation, homes that are designed and constructed to minimize the amount of outdoor air that can ‘leak’ into and out of the home may have higher pollutant levels than other homes. However, because some weather conditions can drastically reduce the amount of outdoor air that enters a home, pollutants can build up even in homes that are normally considered ‘leaky.'”
