The air purifier, also known as "air cleaner", air freshener and purifier, originated in the industrial age of Germany in 1869 and was invented by Martin·Aussdon in Germany. Air purifier refers to a product that can adsorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.) and effectively improve air cleanliness. It is mainly divided into household, commercial, industrial and building.

There are many different technologies and media in the air purifier, which enable it to provide users with clean and safe air. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, super-structure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc. Material technology mainly includes: photocatalyst, activated carbon, synthetic fiber, HEAP high-efficiency material, negative ion generator, etc. The existing air purifiers are mostly compound, that is, a variety of purification technologies and material media are adopted at the same time.

Top ten brands of air purifiers:

1, AUSSDON air purifier

2, Philips air purifier

3, Odeo air purifier

4, Swiss air purifier

5, Bruyal air purifier

6, Honeywell air purifier

7, Conte air purifier. Electrolux air purifier

above brands have been strictly examined, and they all belong to international first-class manufacturers. I also hope that in the air purifier market in China in 215, more new technologies will be introduced to the air purifier market in China, and more families will be provided with safe and healthy products. Until one day we don't use air purifiers, the world will be better!
