Abstract

The present invention relates to an article for use within a non-combustible aerosol provision system and a non-combustible aerosol provision system. The article includes a filter and an aerosol-generating portion comprising an aerosol-generating material and an encapsulated first aerosol-modifying agent. Upon heating, the encapsulated first aerosol-modifying agent is released once a threshold release temperature has been reached. The filter includes a component holding a second aerosol-modifying agent, wherein the second aerosol-modifying agent is selectively releasable from the component.
