A portable pool filter cleaning assembly is configured to retain a pool filter on support rod and allow the pool filter to spin from a spray of water. The spinning filter releases debris from the filter surface through centrifugal force. The assembly has drainage features to ensure proper drainage of water collected within the interior of the pool filter and enable proper spinning from the spray of water. The assembly utilizes a support rod with a bottom filter retainer that is conical in shape for engaging with the pool filter aperture. The bottom filter retainer may further have a bearing that enables the pool filter to rotate freely about the rod with very little force. The assembly may include a stand for securing the support rod on a hard surface, such as concrete or on an uneven lawn surface.

A method for cleaning a particulate matter filter is discussed. The particulate filter can include an inlet and an outlet, where the outlet includes openings to a plurality of outlet channels, and the inlet includes openings to a plurality of inlet channels. The outlet channels and the inlet channels are separated by a filer barrier. A fluid nozzle is positioned in contact with the outlet of the particulate filter over a first set of outlet channels. Fluid form the fluid nozzle is injected into the first set of outlet channels. While injecting the fluid, the position of the fluid nozzle is changed such that the fluid nozzle is positioned over a second set of outlet channels.
