Removal of formaldehyde is complex as it can adopt many forms. In its simplest form, formaldehyde is a gas. It is skin-irritating and exhibits a pungent odour, even at concentrations less than 1 ppm.

SURSORB FORM for formaldehyde (CH2O) removal is a type of performance activated carbon designed for removing formaldehyde. It is then fixed to the activated carbon surface. Its base material is manufactured by activating coconut shell charcoal at high temperatures by steam.  The manufacturing process involves the carefully controlled addition of a highly reactive proprietary impregnation to the internal surface. This is done to ensure high adsorption performance.
