First step : Pre filter Infiltrate the pre filter with natural antibacterial, anti-allergy elements, can effectively restrain the allergen like pollen.Function: can effectively restrain the allergen like pollen.
Second step : high efficiency HEPA filter
High efficiency HEPA filter is specially focused on particle with dia. Bigger than 0.25 micron.
Third step : Activated carbon filter
Activated carbon could powerfully absorb and solidify as well as crystallize, further remove toxic substances such as benzene and other peculiar smell. It can also stop secondary pollution caused by thermal desorption of pollutants.
Fourth step : cold catalyst filter
One side of the double hexagonal honeycomb aluminum substrate is coated with Nano – TIO2 employing the patented titanium technology, with high ability of sterilization and viruses removal. And an efficient formaldehyde remover is painted on the other side to capture formaldehyde in the air, and transform it into carbon dioxide and water after efficient decomposition. Removal rate is as high as 99.9%
Fifth step : anion function
Use anion generator which can produce quality of negative ions, physical absorption, remove peculiar smell, such as formaldehyde, benzene and other organic polluting gases. And it has high efficiency air purification.
