A larger surface with more adsorption sites leads to a longer-lasting filter. Forming accordion folds with the material further increases the ability of Terra’s charcoal filters to effectively remove fumes and odors. This results in millions of diminutive pores that increase surface area bonding sites to adsorb molecules- far more efficient than a non-activated charcoal filter. Terra’s charcoal filters undergo a chemical heating process. There are a couple of methods to making charcoal active.

But did you know your water filter may contain activated carbon? Drinking water is often filtered through activated charcoal to remove certain toxins, and improve the odor and taste. Traditional charcoal is a common commodity, found in everyday-homes (cooking barbecues, vacuum cleaners, etc.). To understand chemical vapor filtration, let’s first focus on what having a carbon-based filter means. Unlike particle filters, which rely on micro-pores to capture solid contaminants suspended in air, Terra’s coconut-shell based charcoal filters remove a wide range of chemical fumes and odors common to laboratories and manufacturing environments. Activated charcoal is highly porous carbon used in air filters to capture solvent fumes and organic compounds by adsorption of molecules (van der Waals forces).
