Why Ventilation Is So Important

According to the Environmental Protection Agency, Americans spend about 90 percent of their time indoors, where concentrations of pollutants are often much higher than those outside. Risk assessments performed for radon, environmental tobacco smoke (ETS), and lead have shown that health risks are substantial.

Thousands of chemicals and biological pollutants are found indoors, many of which are known to have significant health impacts both indoors and in other environments.

Air inside in our homes is up to 100 times more polluted than outdoor air.  If too little outdoor air enters a dwelling, microorganisms can collect to levels that pose health and comfort problems. This problem can be especially serious in the energy efficient homes built in the last twenty years. These homes may not allow enough air changes, keeping contaminated air in and fresh air out.

• The EPA has identified indoor air quality as one of the five most urgent environmental risks to public health.
• The majority of all infections and allergies are passed from one person to the other through the air.
• The National Academy of Sciences Institute of Medicine reports that exposure to indoor pollutants is a key contributor to the asthma problem of this nation.
• Today's tighter, better insulated homes limit natural ventilation and trap indoor air contaminants inside.

The QC-1500 system can also be used to help eliminate pet odors, moisture, burned food smells, and smoke. Every home will benefit from using the QC-1500 system for cooling and ventilating all year round!!
