Domestic removal of indoor air pollution in three ways: 
 A. Physical adsorption: activated carbon adsorption in the air, formaldehyde and other pollutants, such as activated carbon. Or device equipped with an activated carbon active filter the indoor air. For example: air purifier 
 Features: Activated Carbon cheap but the adsorption range, the effect is poor. Air Purifier active absorption filter indoor air but can not remove the source of pollution and expensive 
 Two. Photocatalytic technology: the cold catalyst / photocatalyst technology. Multiple heterogeneous catalysis-based, combined with Supermicro filter, and a variety of harmful and odorous gases broken down into a harmless, tasteless substance, by simple physical adsorption to chemical adsorption, and the life of the adsorption material is several times more than ordinary materials relatively strong, targeted, catalytic decomposition of indoor formaldehyde and other harmful gases. 
 Features: the ability to deal effectively with the current mainstream method 
 Three. Plant absorption technology: The experts developed a variety of deodorant and formaldehyde scavenger, these products are commonly used complexing technology, its active ingredient is the alkaloid extracted from the Lauder, Radix, and other herbs and liquid activated carbon. Can effectively destroy the molecular structure of harmful gases such as formaldehyde, benzene, harmful gases in the air, and then gradually cleared, and ultimately achieve the purpose of improving indoor air quality. Degradation of formaldehyde. 
 Features: affordable, good removal efficiency. Belongs to the latest technology
