Coghlan's Two-Step Drinking Water Treatment is a reliable solution for backpackers and hikers who need access to safe drinking water in the outdoors. With 50 tablets per bottle, it can eliminate bacteria like Giardia from questionable water, and its neutralizer tablets remove the iodine taste from the first step of the treatment. It's a useful backup option when your primary water purification method fails, providing peace of mind on your outdoor excursions. Each treatment disinfects 1 quart of water, making it a practical and compact tool for any outdoor enthusiast.
