There is a growing public awareness and knowledge about poor indoor air quality and its alarming health effects.
Hundreds of community health studies have linked daily increases in fine particle pollution to reduced lung function, greater use of asthma medications, and increased rates of school absenteeism, emergency room visits, hospital admissions, and even tens of thousands premature death each year. Fine particle pollution is especially harmful to children, elderly and people suffering from lung and cardio vascular diseases such as asthma, COPD, artery disease and congestive heart failure. In America alone 20 million people suffer from asthma and 50 million from allergies.
In the last couple of years, scientific evidence has indicated that it is actually the indoor air that is a major health threath being seriously more polluted than the outdoor air in even the most industrialized cities. As people are known to spend approximately 90% of their time indoors, the health risk may be severe.
In conjunction with the European Respiratory Society Congress (ERS) in Stockholm in 2007 WHO published a report stating that one billion of the world’s inhabitants now have chronic lung diseases and that by 2020, these will be the world’s greatest cause of death. This applies to pulmonary infections such as tuberculosis as well as lung cancer and chronic obstructive pulmonary disease (COPD), plus a range of respiratory diseases such as asthma and diseases involving defective breathing regulation, like sleep apnea and sudden infant death. Whilst the incidence of many other major disease groups is declining, lung diseases are on the increase!
