  • Publication number: 20240074490
    Abstract: The present invention addresses the problem of providing: a filter in which a liquid having phenol filtration capability is prevented from leaking out even after prolonged storage; and a flavor inhalation article equipped with said filter. The problem is solved by a filter that is for a flavor inhalation article, and that has a filtering medium including a biodegradable material, and a paper roll wound around the filtering medium. The filtering medium contains a liquid having a phenol filtration capability. A surface of the roll paper where a contact is made with the filtering medium is made of a layer exhibiting liquid-repellent properties with respect to said liquid.
