The history of air purifiers

Here is a brief history of air purifiers.

According to, as many as eight out of 10 allergy suffers experience year-round symptoms due to poor indoor air quality. One of the reasons why we’re committed to supplying people with the best affordable air purifiers is that improving indoor air quality is one of the most effective ways of alleviating allergy symptoms. In fact, looking to purify indoor air so people can breath easier is a practice that comes with a long history.

For almost 200 years now, scientists have been working to improve the quality of air we breathe when we’re indoors. At the start of the United States industrial revolution, a pair of scientists created a mask that helped filter toxic air specifically for firefighters in 1823, allowing them to enter burning buildings without being overwhelmed by the fumes.

That 1823 discovery was revolutionized in 1854 when John Stenhouse improved upon the technology by implementing a charcoal-based filter design. Then, in 1871, John Tyndal advanced the concept further when he introduced the world to the respirator.

During the beginning of the 20th century, the HEPA air purifiers came into existence. Originally intended to protect soldiers and scientists from the fallout of an atomic explosion, HEPA (high efficiency particulate air) devices came to be used instead for eliminating potentially harmful microscopic particles like mold, pollen and other airborne pollutants. The Department of Energy (DOE) ascertained that HEPA filters could remove at least 99.97 percent of all harmful particles at a rate of 85 liters per minute.

With a history deeply rooted in the interest of aiding public service and secret government products, once the late 20th century came into existence, the home air purifier was coming into its own prominence among the public.
