Contains 4 odour absorbing capsules to remove fermentation odours, simply remove the Sterilock lid and fit an odour absorbing capsule by inserting the white (smaller diameter) end into the top of your Sterilock Airlock. Each capsule has been designed to remove fermentation odours over the entire period of an average brew, though they may well last over two or three fermentations. It is recommended that you replace when odours become apparent.
