Listing comes with 3 filters only. The metal filter cage is for reference only.

The filter cage in the picture is from a 20 gallon central machinery parts washer from harbor freight. So it fits the harbor freight unit and similar units from Jegs and other companies.

Can be used on other / larger units if the filter dimensions are about the same.

This parts washer filter measures roughly 4in x 4in. with a 1/4in variation. So the filter can rage from 3.75in to 4.25 basically.

Some filters may require trimming to fit, but all the ones on the smaller side are test fit to make sure they will work with the metal cage pictured.
