3-5mm 4-6mm HCHO absorber activated alumina absorbent ball to removal harmful gases
Activated alumina ball is a chemical adsorption materials, advanced new environmentally friendly catalyst. This product use special activated alumina carrier, after high-temperature solution compression, decompression and other processes of production, with the same product more than twice the adsorption capacity. The activated alumina ball is impregnated with a strong oxidant to use its strong oxidizing property to oxidize and decompose harmful gases in the air to achieve the purpose of purification. It can remove many harmful gases such as formaldehyde (HCHO).
