The automatic filter is an advanced, efficient and easy-to-operate full-automatic filter device. When the filter works, water to be filtered flows in from the water inlet, flows through the filter screen, enters a pipeline required by a user through the outlet to carry out process circulation, and particle impurities in the water are intercepted inside the filter screen. The continuous circulation is that the intercepted particles are more and more, the filtering speed is more and more slow, the sewage at the inlet is still continuously fed, the filtering holes are smaller and smaller, therefore, pressure difference is generated between the inlet and the outlet, when the pressure difference reaches a set value, namely, the filter element needs to be replaced or cleaned, and after the filter screen is cleaned, the pressure difference is reduced to the minimum value, the system returns to the initial filtering state, and the system normally operates.
