Apparatus for conditioning refillable articles for aerosol provision systems

A refilling device for filling an article from a reservoir, comprising:

• an article interface for receiving an article of an aerosol provision system, the article having a storage area for fluid and an atomiser having porosity for absorbing fluid from the storage area and comprising an electrically conductive heating member for vaporising the absorbed fluid;
• an air pump for removing air from inside an article received in the article interface;
• and
• a controller configured to:
• execute a filling action to deliver fluid to the storage area of the article;
• and
• during the filling action and/or on completion of the filling action, operate the air pump to reduce air pressure inside the article for a wetting period to promote flow of fluid from the storage area into the atomiser.
