Eight Mind-blowing Statistics About Indoor Air Quality
- According to both Total Health and Better Health Magazines, 1 in 6 people who suffer from allergies have them directly due to bacteria and fungi in unclean or never-cleaned HVAC Air Duct systems.
- Almost 1 in 10 people in the UK have asthma. That’s over 5.4 million people, or about 9% of the population. And it’s a serious condition. This is only one country, imagine around the globe.
- Every one out of ten office fires is caused by poorly maintained ducts.
- A ventilation system will pull the air in a room through itself and re-circulate it around the buidling between 5 and 7 times a day. Any contaminants in the vents will get 5-7 chances a day to infect you.
- The Environmental Protection Agency (EPA) in America have done research that shows that the level of pollutants indoors is “2 to 5 times – and occasionally more than 100 times” higher the outside air. The average adult inhales 2 tablespoons of dust daily.
According to the Duct Cleaners Association (NADCA), the average 5000 sq feet office space has 80 Kgs or 40 pounds of dust and dirt in its vents. Imagine how much more is in an industrial kitchen or a high traffic area like a Commercial building, or a Train station or Airport.- The American College of Allergists claim that nearly 50% of all illnesses are caused by, or aggravated by, contaminated indoor air.
- As little as 0.042 of an inch of build-up of dirt on a heating or cooling mechanism can reduce its output by almost 50%.
