In 1823, John and Charles Dean invented a new type of smoke protection device that allows firefighters to avoid smoke when fighting fires.


In 1854, a man named Johns Tenhouse made new progress based on the invention of his predecessors: after 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 to conduct research on radioactive materials. They needed to develop a way to filter out all harmful particles to keep the air clean, so HEPA filters came into being. In the 1950s and 1960s, HEPA filters were once very popular, and they were very popular among air-raid shelter designers and construction personnel.


In the 1980s, home air purifiers were born. The purifiers at that time could only remove bad smells, toxic chemicals and toxic gases in the air.


In the new century, the development of air purifiers changes with each passing day. It can not only clean the toxic gases in the air, but also purify the air to remove bacteria, viruses, dust, pollen, mold spores, etc. in the air.


Hanlang introduced German technology, among which the formaldehyde decomposition technology is the ultimate in air purification technology. Not only can it adsorb formaldehyde, but it can also decompose formaldehyde into carbon dioxide and water molecules to prevent secondary pollution of formaldehyde.


With the increase of family cars and the intensification of environmental pollution in the car, car air purifiers came into being. In September 2013, the birth of a certain series of car air purifiers was a symbol of the leading international level in the domestic car purifier industry.

Remote control technology has always been a difficult problem in the field of car cleaning air purification. Using network signal control is prone to the problem that the switch cannot be controlled without a wifi network signal. The 3GS intelligent remote control pioneered by Hanlang on the whole network can be switched on and off by phone or SMS as long as there is a mobile phone signal.

This innovation has pushed the car air purification technology to a new level. Nowadays, air purifiers are not a new product, they are becoming a household necessity. From military to civilian use, air purifiers are constantly innovating and breaking while entering thousands of households.

Air purifiers have been designed and manufactured in many different ways, and every technological change has brought significant effects to the improvement of people's indoor air quality. And all this has only one purpose: hope to purify indoor air to improve people's quality of life. In order to let more people enjoy a better life, Hanlang has been acting.
