Abstract
A filter cartridge for a standalone point of use water purification device includes tandem first and second flow passageways containing flowthrough filter media that cooperate to provide opposing flow directions in the first and second flow passageways that reduce, if not eliminate, channeling, and provide self-wetting of the flowthrough filter media contained in the tandem first and second flow passageways, eliminating the need for post-use wetting steps.
