The heat-not-burn cigarette filter (10) comprises a first portion and a second portion connected with each other, the first portion is a filter rod (100), the second portion comprises at least one hollow portion (300) and at least one cooling portion (200), the cooling portion (200) comprises at least one through hole (210), and the middle part of the hollow portion (300) is in a through cavity structure. The heat-not-burn cigarette filter (10) of the present disclosure includes the filter rod (100), the cooling portion (200), and the hollow portion (300).
