TiO2-impregnated titanium mesh filter (TMiP) elaborated by electrochemical anodization of the titanium mesh, followed by dip coating into TiO2 anatase solution, was used for the removal of cigarette smoke as a principal indoor air pollutant. The TMiP catalyst revealed high activity for the removal of ammonium, nicotine, 3-ethenylpyridine, and tar, which constitute some of the volatile and nonvolatile compounds of cigarette smoke. As a practical application, an air purifier has been developed and tested for the removal of cigarette smoke.
