Ventilation
 

Fresh Air The purpose of ventilating a home is to maintain a healthy and safe living environment by supplying fresh air and removing stale, 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 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 substantially, the result is stale and polluted air. New homes are constructed to be as energy efficient as possible which eliminates natural ventilation (also known as leakage).

Whole-house or controlled ventilation is designed to address the ventilation needs of the home's occupants.  The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) recognizes ventilation as a critical part of a healthy environment, and is joined by such groups as the Environmental Protection Agency, American Medical Association and the American Lung Association.  The benefits of ventilation include providing fresh air to the occupants and diluting the concentration levels of common household contaminants such as carbon dioxide.

ASHRAE Standard 62.2 specifies the amount of fresh air a building should have, based on the number of occupants the home is designed for and the overall size of the home. The ASHRAE standard is recognized by most local codes as the minimum amount of ventilation required for residential buildings. Ultra-Aire whole house ventilating dehumidifiers are an effective and efficient solution to meeting this standard.

For the ultimate in indoor air quality install an Ultra-Aire whole house ventilating dehumidifier.
