Safe drinking water — anywhere. These tablets make untreated water drinkable when you’re camping, travelling internationally, hiking, boating, or building an emergency kit. Drop one tablet into 1 litre of clear water, wait the required contact time, and you’re good.
They’re effective against bacteria, viruses, and Giardia cysts — and they don’t add the harsh taste or colour that older treatments sometimes did. Each tablet is individually foil-sealed with a long shelf life, so they’re easy to stash in a pack, first-aid kit, or glove box.
For murky, cold (4 °C) or visibly dirty water, simply double the dose.
