Abstract

There is provided a non-combustible aerosol delivery system for filtering exhaled breath, the aerosol delivery system including a power source; a filter unit; an inhalate airflow path adapted to convey vapor generated by the aerosol delivery system to the user during an inhalation, and an exhalate airflow path adapted to convey breath from the user to the filter unit during an exhalation into the aerosol delivery system; wherein the filter unit contains at least one filter, and wherein the at least one filter comprises glass fiber, polypropylene, or combinations thereof.

Claims (20)

1 . A non-combustible aerosol delivery system for filtering exhaled breath, the aerosol delivery system comprising:

a power source;

a filter unit;

a unit containing a vapor forming material;

an inhalate airflow path adapted to convey vapor generated by the aerosol delivery system to a user during an inhalation, and

an exhalate airflow path adapted to convey breath from the user to the filter unit during an exhalation into the aerosol delivery system, wherein at least a portion of the inhalate airflow path and a portion of the exhalate airflow path are the same;

wherein the filter unit contains at least one filter, and wherein the at least one filter comprises glass fiber, polypropylene, or a combination of glass fiber and polypropylene;

wherein the filter unit and the unit containing the vapor forming material together form a single assembly which is removable from the non-combustible aerosol delivery system.

2 . The non-combustible aerosol delivery system of claim 1 , wherein the at least one filter comprises glass fiber.

3 . The non-combustible aerosol delivery system of claim 2 , wherein the at least one filter comprises at least a first filter comprising glass fiber, and a second filter which is a HEPA filter.

4 . The non-combustible aerosol delivery system of claim 1 , wherein the at least one filter comprises polypropylene.

5 . The non-combustible aerosol delivery system of claim 1 , wherein the filter unit further comprises a separator for separating aerosol droplets from vapor.

6 . The non-combustible aerosol delivery system of claim 1 , wherein the filter unit further comprises a vortex separator.

7 . The non-combustible aerosol delivery system of claim 1 , wherein the filter unit further comprises a complex flow path separator configured to elongate a path along which an exhalate flow travels.

8 . The non-combustible aerosol delivery system of claim 1 , wherein the filter unit further comprises a water filtration unit, the water filtration unit comprising water through which exhalate may be passed to filter the exhalate.

9 . The non-combustible aerosol delivery system of claim 1 , wherein the filter unit comprises at least one deodorizing filter.

10 . The non-combustible aerosol delivery system of claim 1 , wherein the at least one filter comprises activated carbon.

11 . The non-combustible aerosol delivery system of claim 1 , wherein the non-combustible aerosol delivery system is an electronic cigarette.

12 . The non-combustible aerosol delivery system of claim 1 , wherein the non-combustible aerosol delivery system is an aerosol generating material heating system.

13 . The non-combustible aerosol delivery system of claim 1 , wherein the non-combustible aerosol delivery system generates aerosol using a combination of aerosol-generating materials, and wherein one or a plurality of the aerosol-generating materials may be heated.
