As many as 8 out of 10 allergy sufferers have allergy symptoms year-round due to indoor allergens. Perennial allergy symptoms can be controlled by improving indoor air quality with air purifiers. These days, there are so many options for air cleaning: furnace filters, HEPA air purifiers, Pass box, humidifiers that wash the air, ozone generators, and whole house air purification systems, which may leave the allergy consumer wondering: How did we get this far with air cleaning technology?
You may think that air purification is a new craze, but in actuality, it dates much farther back than most people realize. Although antiquated, various types of air purification have been around for more than 200 years. Since the early 1800s, scientists have been working on ways to make our air cleaner. At the start of the industrial revolution in the United States, John and Charles Dean developed a mask for firefighters in 1823, allowing firefighters to enter burning buildings without being overcome by dangerous smoke fumes.
As the Industrial Revolution really took hold in America, coal burning became a basic way of life throughout growing cities. Utilizing coal allowed engineers to produce electricity and fuel to power trains and heat homes. However, as coal became a central resource for growing city life, the air became polluted with smoke and dark clouds of smog.
It was not until 1854 that John Stenhouse developed a mask worn by divers and coal miners to protect against polluted air. Stenhouse’s mask was based on a charcoal-based filter design, similar to some of the carbon filters used in air purifiers today. These masks filtered many air impurities and made tremendous advancements in the field of air purification. Using charcoal in his air filters enabled Stenhouse to filter out more harmful, noxious gases from the air than previous filtration masks. In 1871, John Tyndall upgraded the original firefighter masks created by the Deans, introducing a respirator to aid in the breathing for firefighters. The combination of the respirator device and filtration system became early precursors to today’s respirator masks.
HEPA Air Filters
You may not know it, but HEPA filters were originally classified as top-secret, developed by the US Atomic Energy Commission to protect soldiers from radioactive particles on the battlefield. During World War II, scientists involved in the Manhattan Project used HEPA masks to guard against contaminants from the atomic bomb.
Although these early HEPA masks couldn’t possibly protect people from atomic radiation, the research spawned the HEPA filter, which provided protection against chlorine gas, mustard gas, and pollutants from flame throwers. It was not until the 1960s that specifications were standardized and the term HEPA or “High Efficiency Particulate Air” was officially coined by the Department of Energy (DOE).
As defined by the DOE, HEPA filters remove at least 99.97% of dust, pollen, mold, bacteria and any airborne particles with a size of 0.3 microns at 85 litres per minute. From the beginning, HEPA filters were employed to filter out highly hazardous aerosols, toxic carcinogens, radioactive particules, and biohazardous contaminates.
Meanwhile, across the world in Germany, brothers Klaus and Manfred Hammes purchased a patent for a simple air filtration system. Using a fiberglass pad attached with small magnets to the air outlet of a residential oil oven, the Hammes brothers were able to filter soot from the air. In 1963, the Hammes brothers’ simple but effective filter became the first air cleaner to be utilized in homes across Germany.
Coincidentally, in the same year, US Congress passed the Clean Air Act of 1963 to set standards for the reduction of air pollution through fuel emissions standards. Although it was not Congress’s first attempt at reducing air pollution, the Clean Air Act of 1963 alerted scientists and consumers of the need to protect our lungs from pollutants such as perfumes, building materials, chemicals, pesticides, and allergens.
In 1991, through the amazing technology of True Medical HEPA and Activated Carbon, Richard Taylor created a filter that addressed the issues of environmental particulate contamination, chemical toxicity, and odors. It was then that he and his wife Joyce founded Austin Air Systems Limited. Based out of Buffalo, NY, Austin Air introduced a pre-filter that ensured a HEPA filter life unequaled to anything in the industry. Austin Air’s 360-degree intake system draws air into all sides of the Air shower, maximizing efficiency and delivering more clean air faster. With the largest air cleaner manufacturing facility in the world, Austin Air continues to produce all the parts for their fantastic air purifiers.
Wuxi Xinda Cleanse Air-condition Whole Set Factory established in August, 1992, is engaged in the engineering design, manufacture, installation and debugging of air-condition cleanse and the producing of air cleaning products.
Although no longer a top-secret government project, air purifiers still hold the secrets to cleaner air and healthier environments for many asthma and allergy sufferers. Today HEPA air purifiers and filters are used in a variety of critical filtration applications in nuclear, electronic, aerospace, pharmaceutical and medical fields, as well as in homes around the world.
