The emergence and development of air purifiers

air purifierThe emergence and development of

air purifierOriginating from firefighting purposes, in 1823, John and Charles Dean invented a new type of smoke protection device that allowed firefighters to avoid smoke invasion while extinguishing fires.

In 1854, a man named John Tenghaus made new progress based on the inventions of his predecessors: through several attempts, he learned that adding charcoal to an air filter could filter out harmful and toxic gases from the air.

During World War II, the US government began researching radioactive materials and needed to develop a way to filter out all harmful particles to keep the air clean so that scientists could breathe. As a result, HEPA filters emerged. In the 1950s and 1960s, HEPA filters were very popular and favored by personnel designing and constructing air raid shelters.

In the 1980s, the focus of air purification shifted towards methods such as household air purificationair purifierIn the past, filters were very good at removing odors, toxic chemicals, and toxic gases from the air, but they could not remove mold spores, viruses, or bacteria, which are now used in new homes and workspacesair purifierNot only can it clean the toxic gases in the air, but it can also purify the air and remove bacteria, viruses, dust, pollen, mold spores, etc. from the air.

Now,air purifierThere are already various design and production methods, and every technological change has brought significant effects on improving indoor air quality for people. And all of this has only one purpose: to purify indoor air and improve people's quality of life.
