Abstract
An inhaler article () includes a body () extending along a longitudinal axis of the inhaler article from a mouthpiece end () to a distal end (), a capsule cavity () and a capsule () retained within the capsule cavity. The capsule cavity is defined within the body and bounded downstream by a filter element () and bounded upstream by a tubular element () defining a central passage () in fluid communication with the capsule cavity. The central passage forms an air inlet aperture extending along the longitudinal axis of the inhaler article from the distal end of the body towards the capsule cavity, wherein the tubular element has a central passage inner diameter in a range from about 50% to about 90% of an inner diameter of the capsule cavity. The inhaler article is configured to receive a swirling inhalation airflow into the central passage.
