First Stage : Pre Filter
Using 60 mesh ultrafilter, mainly filter particles in the air, washable.
Second Stage : ESP compound filter
Made of porus coconut activated carbon+formaldehyde treasure+ aluminum honeycomb and
ionization technology of negative high voltage, effectively eliminate airborne smoke and kill
airborne bacteria and viruses, effectively absorb formaldehyde, benzene, airborne peculiar smells
Third Stage :HEPA filter
Take advantage of HEPA, effectively filter airborne allergen, such as acarid, pollen, germs,
second-hand smoke, dust, etc. The filter has purification efficiency is as high as 99%, and can
filter particulates as small as 0.3μm.
Fourth Stage : Ultrahigh density of anion technology.
Anion is in the medical field known as the vitamin in the air, people live in higher density of anion
environment, it can promote the metabolism, and increase the human immunity. The air filter
brings 3 million anion per second, making you always feel in waterfalls and refresh forest.
