A tobacco smoke filter comprising a porous substrate having a humectant, such as sodium pyroglutamate, dispersed therein to absorb moisture from the tobacco smoke thereby wet-filtering the tobacco smoke. Also, a tobacco smoke filter comprising a porous substrate having microcapsules dispersed therein. The microcapsules comprise a humectant such as sodium pyroglutamate. The microcapsules further preferably comprise one or more of methylcellulose, chlorophyllin and at least one vegetable oil.
