A portable water filtration system filters water as it flows through an inlet of a conventional storage container and removes impurities before they enter the container. The filtration system is implemented within a cap that can attach to a variety of standard water storage containers, such as Nalgene™-type water bottles. When attached to the storage container, the cap seals around the container inlet and prevents the outer surface of the container inlet from contacting the water. To that end, two watertight seals are formed to isolate the outer surface of the inlet from any fluid communication, e.g., during a water-filling process. Because the outer surface of the inlet does not contact the unfiltered water, no contaminants can adhere to the inlet's surface and threaten a drinker's health if he/she drinks directly from the storage container after the cap is removed. The filtration system may be detachable from the base, such that the filtration system can be removed while the filtered water is disinfected using known ultra-violet (UV) and chemicals. In one embodiment, the filtration system may be cleaned and reinserted in an opposite orientation to seal the filtered and treated water in the container.
