As many as 8 out of 10 Allergy sufferers have allergy symptoms due to allergens. Perennial allergy symptoms can be controlled by improving indoor air quality with air cleaners. Nowadays, there are a lot of possibilities for air cleaning: furnace filters, HEPA air purifiers, ionic air cleaners, humidifiers that clean the atmosphere, ozone generators, and whole house air purification systems which may leave the allergy consumer wondering: How can we get this far with air cleaning technologies You may think that atmosphere Purification is a new trend, but in actuality, it dates much further back than most folks realize. Although antiquated, various types of air purification have existed for at least 200 years. Since the early 1800s, scientists have been working on ways to make our air cleaner.
At the beginning of the industrial revolution in the USA, John and Charles Dean developed a mask for firefighters in 1823, allowing firefighters to enter burning buildings without being overcome by harmful smoke fumes. As the Industrial Revolution took hold in the USA, coal burning became a simple means of life throughout growing towns. Utilizing coal enabled engineers to create fuel and electricity to power trains and heating houses. However, since coal became a central resource for developing town life, the atmosphere became contaminated with smoke and dark clouds of smog. It was not until 1854 That John Teahouse developed a mask worn by sailors and coal miners to protect against contaminated atmosphere. Teahouse’s mask has been based on a charcoal-based filter design, like a number of the carbon filters used in air purifier and humidifier now. These masks filtered many air impurities and made tremendous advancements in the field of air purification.
Using charcoal in his air filters allowed Teahouse to filter out more harmful, noxious gases in the atmosphere than previous filtration masks. In 1871, John Tyndall updated the original firefighter masks made by the Deans, introducing a respirator to assist in the breathing for firefighters. The combination of this respirator apparatus and filtration system became ancient precursors to today’s respirator masks. Atomic Energy Commission to protect troops from radioactive particles on the battlefield During World War II, scientists involved with the Manhattan Project utilized HEPA masks to guard against contamination from the nuclear bomb. Although these early HEPA masks could not possibly protect people from nuclear radiation, the study spawned the HEPA filter, which provided protection against chlorine gas, mustard gas, and flame throwers. It was not till the 1960s that specifications were standardized and the expression HEPA or High Efficiency Particulate Air was coined by the Department of Energy DOE.
