Abstract
An aerosol generating article (10) for use with an aerosol generating device includes an aerosol forming substrate (20) an aerosol cooling element (40) and an acid. The article may optionally include one or both of a filter and a support element (30). The aerosol cooling element, the filter, if present, and the support element, if present, are downstream of the aerosol forming substrate. The acid is downstream of the aerosol forming substrate and is positioned to interact with aerosol from the aerosol forming substrate when the aerosol generating article is used with the aerosol generating device. The acid may be in or on one or more of the aerosol cooling element, the filter, and the support element. The acid may selectively remove ammonia from aerosol generated by the article during use.
