The HaloPure AC filter cartridges are designed for use in pour-through water pitcher filters and portable water bottle filters. Per your submission, the filter cartridges are assembled and filled with the composite filtration media in China, packaged, and subjected to ionizing radiation to ensure sterility. The finished cartridges are subsequently shipped to the United States, where they will be sold both with and without an associated bottle or pitcher.
