Click:24 Time:2018-10-27 11:38:27

The air purifier originated from the use of fire protection. In 1823, John and Charles dean invented a new type of smoke protection device, which enables firefighters to avoid smoke attack when fighting a fire.


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


During world war ii, when the U.S. government started doing 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.HEPA filters were popular in the 1950s and '60s, and were popular with bomb shelter designers and builders.


Entering the 1980s, the focus of air purification has shifted to air purification methods, such as household air purifiers.Past filter in removing the stench in the air, toxic chemicals and poisonous gas is very good, but cannot remove mould spore, the virus or bacteria, and the new family and office use air purifier, not only can clean the toxic gases in the air, also can purify air, remove the bacteria, viruses in the air, dust, pollen, mold spores, etc.


Air purifiers have been designed and manufactured in many different ways, and each technological change has brought remarkable effects to people's indoor air quality improvement.And all these purposes only one: hope can purify indoor air to improve people's quality of life.

Most of the air purifiers on the market mainly consist of: chassis, filter section, air duct design, motor, power supply, LCD screen, etc.The life is decided by the motor, the purification efficiency is determined by the filter section, and the quiet is decided by the air duct design, housing, filter section, motor.
