Why you should be concerned about the quality of indoor air?

• Air pollution poses a health hazard in forty percent of all buildings, according to the World Health Organization.

• Twenty percent of all employees suffer major illness related to indoor air pollution. Illnesses include allergies, asthma, and auto-immune disease.

• Some 6,000 new chemical compounds are developed each year. Many of these are used indoors, at home or at work. Their fumes join with those of older compounds, such as the formaldehyde used in carpet and building materials.

• On average, indoor air is 2-10 times more polluted than the worst outdoor air.

• Virus and bacteria, including those that cause the flu and TB, thrive in the ductwork and heating/cooling coils of air conditioning systems. Some HVAC systems have been found to contain up to 27 different species of fungi.

Based on information given at the First Annual Air Quality Convention sponsored by the EPA, Tampa, Fl, April 1992.

What is the ideal location within a room?

In a central location, six feet (or more) off the floor; ideally close to a cold-air return of the home's HVAC (heating, ventilation, air cooling) system, or close to the source of odors.

In a 2500 sq. ft. house, how many units are recommended?

Placement of units is determined by individual needs and conditions. Are there pets in the home, high pollen count in the area? How many heating/ cooling zones? One unit may be sufficient if placed in the ideal location close to the cold-air return of the HVAC system. (HVAC: heating, ventilation and air cooling)
