Charcoal Odour Absorber

Details

Steam-activated coconut-shell carbon in a breathable, dual-layer sachet with an unbleached cotton canvas outer bag, for a fridge, a shoe rack, a wardrobe, or a car cabin. It works by physical adsorption: odour molecules stick inside the microscopic pores of the carbon until the pores are full. Everything true about this product follows from that physical reality. The first thing it means is that surface area is the whole product, and it is almost never printed. Ours is 1050 square metres per gram by nitrogen adsorption, with an iodine number of 1000 mg per gram measured by the method in IS 877. That matters because a great many charcoal odour bags on sale are simply carbonised wood or bamboo, not steam-activated, which is a different and much cheaper process that leaves a fraction of the pore structure; without an iodine number, there is no way to tell a real adsorbent from ground barbecue charcoal in a cloth bag.

• 100% Steam-Activated Coconut Carbon: Pure agricultural coconut shell carbon activated with high-temperature steam at 850°C to 1000°C. Delivers over 85% micropores under 2 nanometres that trap small gaseous malodour molecules down to parts-per-billion levels.
• Dual-Layer Dust Containment: Solves the universal defect of charcoal bags leaking black dust. An ultrasonically sealed SMS micro-barrier inner envelope (5 to 15 micron pore size) traps 100% of carbon attrition fines with zero gas-diffusion resistance, enclosed inside a durable 220 GSM unbleached cotton canvas outer pouch.
• The Truth About Sun Regeneration: The category claims direct sun recharges carbon for two years. That is thermodynamically untrue for smells: midday sun brings the bag to roughly 55°C, which drives off trapped water vapor and genuinely restores damp-control, but does almost nothing to the organic molecules that cause odour (which require industrial kilns at 150°C to 650°C).
• Honest Finite Replacement: Activated carbon holds 10% to 25% of its own weight in adsorbed organics and then it is full. Replace the 75 g bag at four months in a fridge (up to 250 L) or shoe rack; replace the 200 g bag at six months in a wardrobe or car cabin (up to 3 cubic metres).
• Where It Works and Where It Does Not: Works only in enclosed, low-airflow spaces. A passive bag in an open bedroom does nothing measurable because ambient air exchange outpaces passive diffusion by a wide margin.
• Food-Contact Safe in Fridge: Safe alongside food, produce, and dairy. Zero synthetic fragrances, zero masking chemicals, zero volatile solvents, and zero particles to migrate.
• Zero-Waste Circular Disposal: At end of life, cut the bag open and dig the carbon into plant pots or garden compost. It acts as permanent biochar, improving soil moisture retention and microbial aeration. The natural cotton canvas bag composts in garden soil within 8 to 12 weeks.
• 100% Plastic-Free Presentation: Packaged in an FSC-certified 300 GSM unbleached virgin kraft paper belly band printed with vegetable-oil ink. Zero polybags, zero shrink wrap, zero plastic pods.
