Clean Air for All

With the increase in air pollution, there are things you need to know to keep your air supply clean and refreshed.



“The air at 500 km is so thin that a molecule will travel an average of 30 km before it collides with another molecule.”  —Ray Roble, Senior Scientist High Altitude Observatory National Center for Atmospheric Research

“Many particles of different types and sizes are carried in the air we breathe. Some large particles may settle on the walls and furniture in your home. Other large particles are removed by your nose and mouth when you inhale. Smaller ­particles are breathed deep into the lungs.”  —American Lung Association
Before Mechanical Cooling . . .“People spent summer days and evenings on porches or fire escapes. They cooled off by getting wet—opening up fire hydrants, going to the beach, diving into swimming holes.”  —Stay Cool! Air Conditioning in America National Building Museum Exhibition, Washington, D.C. Through January 2000
“Domestic air conditioning meant that traditional architectural features—wide eaves, deep porches, thick walls, high ceilings, attics, and cross ventilation—were no longer needed to promote cooling.” (But . . . architects are bringing these features back.)  —Stay Cool! Air Conditioning in America National Building Museum Exhibition, Washington, D.C. Through January 2000
“Wind projects today are being installed for less than five cents per kilowatt-hour, nearly a 100 percent decrease in cost from the early 1980s.”  —Princeton Economic Research Inc.
Cooler air holds less water vapor . . . which explains condensation.
