Abstract
A portable water purifier includes a portable ozone generator and water container and a flexible tube conducting ozone from the generator to the container. A filter-bubbler is used to bubble ozone into water in the container and then to filter the purified water as it is drawn from the container with the flexible tube serving as a siphon. A vent for the container contains an ozone decomposition catalyst for decomposing any ozone in the vented gas.
