The RapidPure^® Intrepid Bottle gives you the power to filter and purify water in an ultralight purifying water bottle perfect for hiking, backpacking, traveling, and everyday use. More than a filter, this 25 oz. water bottle purifier removes over 99.99% of viruses, bacteria, parasites, sediment, and more, and works even after it has been frozen. The UltraCeram^® technology acts like a magnet to remove pathogens 100 times smaller than traditional microfilters can remove. Featuring a flip top lid and ergonomic design, the Intrepid requires no pressing, squeezing, or priming – just fill and drink.
