The upper end of the cylinder of a fluid filter is provided with a support flange and an end cap, between which a hollow cavity is provided; the upper end of the end cap is provided with an adapting flange with a water inlet. The support flange is provided with 3-10 through holes beneath which interfaces are provided. The end cap and the support flange are sealed and fixedly connected with the cylinder. Water outlets are arranged on the bottom of the cylinder, and water returning ports are arranged on the side of the cylinder. A lower pressure plate with through holes with upper interfaces is pressed on a boss in the cylinder, and a hollow cavity is arranged between the boss and the bottom of the cylinder; the upper ends and the lower ends of a plurality of tubular filter nets are respectively connected to be fixed to the interfaces of the through holes of the support flange and the lower pressure plate. The fluid is filtered via the filter net and is sent to an apparatus through the water returning port; the impurity falls into the hollow cavity between the lower pressure plate and the bottom of the cylinder to be temporarily stored, which avoids the filter net being blocked, largely reduces the changing frequency of the filter net, and extends the service life of the filter net; the impurity can be exhausted as long as the water outlet is opened. Each part is sealed, which ensures that the fluid can not externally leak. A plurality of filter nets improve the throughput of the filter. The filter is suitable to filter the fluids of various chemical devices, and is especially suitable to filter the superheated water, the steam and the power water, etc. in the tire vulcanizer.
