Where the air stands still.

Activated bamboo charcoal adsorbs odours without adding fragrance. Place the pouches in wardrobes, shoe cabinets and other enclosed spaces.

Where you sleep

Beside the bed.

Out of the way but not shut in — a nightstand, a shelf, the back of a drawer.

Adsorption, not absorption.

Absorption is a sponge soaking up water — molecules move into the body of the material. Adsorption, with a "d", is something else: molecules bind to the surface, held by weak chemical attraction.

Each gram of activated bamboo charcoal holds roughly 1,300 m² of internal surface area — about three basketball courts of microscopic landing pads, folded into the material. Odour molecules, formaldehyde, ambient humidity — all bind to those surfaces and stay bound.

At least two hours of direct sun once a month refreshes the pouches. Heat weakens the bonds, releasing what was held, and the surface is ready to adsorb again. Two years of quiet work. Two hours of sun. Repeat.
