Abstract
Embodiments relate generally to a self-cleaning filter. A filter may include a tube comprising perforations. The tube may be configured to receive a flow of a liquid from a first direction or a flow of a gas from a second direction opposite to the first direction. The filter may also include a filter media positioned concentrically around the tube, and spacers positioned between the tube and the filter media to create a space between the tube and the filter media. A portion of the filter media is configured to flex inward into the space during the flow of liquid into the filter, and flex outward from the space during the flow of gas exiting the filter.
