Abstract

The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. For example, some aerosol delivery devices of the current disclosure include a reservoir having a liquid aerosol precursor composition, an electrical heater in fluid communication with the reservoir and configured to vaporize the liquid aerosol precursor composition to form an aerosol, and a filter operatively arranged relative to the electrical heater such that at least a portion of the formed aerosol passes therethrough, the filter being configured to selectively bind one or more undesirable impurities.

Dependent claims

An aerosol delivery device comprising:

a vaporization component configured for vaporization of an aerosol precursor composition to subsequently form an aerosol optionally including one or more target compounds;
a filter comprising a cellulose-containing material and ion-exchanged fibers including functional groups selected from nucleophilic functional groups and electrophilic functional groups, the filter being operatively arranged relative to the vaporization component such that at least a portion of the formed aerosol passes therethrough, the filter being configured to bind selectively one or more of the target compounds;
wherein the one or more target compounds comprise one or both of carbonyl-containing compounds and nitroso-containing compounds.

Dependencies are inferred from the claim text.
