From asthma to allergies, poor indoor air quality is harmful to people's health

• Most Americans spend about 90% of their time indoors

• Indoor air is (on average) 7-10 times more polluted than outdoor air

• Airtight construction methods, while making homes more energy-efficient, have led to reductions in indoor air quality, and have created the need for high-efficiency air filtration

• Allergy and asthma sufferers live in 1/3 of all US homes

• 99% of the harmful respirable suspended particles (RSPs) in indoor air are too small to see

• A few examples of RSPs are include: ETS (environmental tobacco smoke), bacteria, fungi, pollens, pet dander and plant spores

• To remove RSPs from indoor air, the EPA recommends use of the internal HVAC system, which circulates 100% of the air, in conjunction with in-duct Electronic Air Cleaner (EAC) technology

• Independant experts and consumer watch-dogs have found that the EAC was the only technology with the potential to separate and remove RSPs from the air stream
