Air purifiers originated from firefighting purposes. In 1823, John and Charles Dean invented a new type of smoke protection device that allows firefighters to avoid smoke during firefighting.
In 1854, a man named Johns Tenghaus made new progress on the basis of his predecessors: through several attempts, he learned that adding charcoal to the air filter can filter out harmful and toxic gases from the air. .
During World War II, the US government began research on radioactive materials. They needed to develop a way to filter out all the harmful particles to keep the air clean and allow scientists to breathe, so the HEPA filter came into being. In the 1950s and 1960s, HEPA filters were very popular and were very popular with air-raid design and construction personnel.
In the 1980s, the focus of air purification has shifted to air purification methods, such as home air purifiers. Past filters are very good at removing malodors, toxic chemicals and toxic gases from the air, but they cannot remove mold spores, viruses or bacteria, and new household and office rooms use air purifiers to clean not only toxic gases in the air. It can also purify the air and remove bacteria, viruses, dust, pollen, mold spores, etc. from the air.
Air purifiers have come in many different ways of designing, and every technological change has brought significant effects to the improvement of indoor air quality. And there is only one purpose for all of this: I hope to purify indoor air to improve people's quality of life.
Most of the air purifiers on the market are: chassis casing, filter section, duct design, motor, power supply, LCD screen, etc. The motor that determines the life is the filter section that determines the purification performance. The airway design, the chassis casing, the filter section, and the motor are determined whether it is quiet. Purchase and maintenance
