The utility model discloses an air filter and a device with the same. The air filter comprises a casing, a partition plate and a filter core, wherein a cavity is defined in the casing, the cavity is divided into a first cavity body and a second cavity body by the partition plate, the size of the first cavity body is larger than that of the second cavity body, the first cavity body is communicated with the second cavity body through a connecting channel, and the first cavity body is divided into an upper cavity body and a lower cavity body by the filter core. According to the air filter, the cavity is divided into the first cavity body and the second cavity body by the partition plate, the size of the first cavity body is larger than that of the second cavity body, and the first cavity body is communicated with the second cavity body through the connecting channel. The connecting channel and the larger second cavity body can jointly form a resonant cavity, and the resonant cavity can be integrated to the air filter. Thus, the resonant cavity and the air filter can be produced through the same set of developing mould, the producing period is shortened, and the producing cost is reduced.
