Abstract

A filter for use in filtering a fluid slurry that includes particles of varying size, such as pool water including debris, is provided. The filter is in electrical communication with a sensor and includes a housing having an inlet to receive the fluid slurry, an outlet, and an internal chamber. An actuator can be coupled to the filter media to move at least a portion of the filter media to vary a dimension of the pores. The filter also includes a controller connected to the actuator that is capable of receiving a signal from the sensor and controls the actuator to change the dimension of the pores based on the signal.
