The Effects of Indoor Air Pollution

According to the EPA (U.S. Environmental Protection Agency) indoor air pollution can have serious and harmful effects on your health just as outdoor air pollution can.

In fact, indoor pollution may even “...be two to five times - and occasionally more than 100 times - higher than outdoor levels.”

This should be of concern to us all since we spend nearly 90% of our lives indoors.

Benefits of Good Indoor Air Quality (IAQ)

Good IAQ is an important ingredient leading to overall better health. This includes improvements in both long and short term ailments as well as certain life threatening conditions. Even some short term discomforts such as headaches, fatigue, sneezing, etc. may be alleviated. Improving IAQ are often leads to lower absenteeism as well as increased performance.

Higher energy efficiency also reduces utility costs and ongoing maintenance.

Fred Ringe - EMA Chicago, Inc.

Fred Ringe, principal of EMA Chicago, Inc., holds a Bachelor and Master Degrees in Mechanical Engineering from Michigan State University as well as an MBA from NIU and is an acclaimed author and lecturer in his field. His first love and primary concentration has always been in the field of fluid mechanics and heat transfer. This enabled him to analyze and find solutions to building system problems including air circulation in school classrooms that have improved air quality and stabilized room temperature since 1994.

What started from a casual conversation grew into a serious business. Fred later coupled his patented process with two related technologies, air ionization units and air filters. Combined, they represent an intelligent and economical means to improve air quality and increase energy efficiency.
