Abstract: A spray gun reservoir including a cup, a lid, and a filter. The cup defines an internal containment volume. The lid defines an outlet. The filter is disposed between the containment volume and the outlet such that liquid flow from the containment volume to the outlet interfaces with the filter. The filter includes a knitted fabric filter media. The knitted fabric filter media can include filaments knitted in a pattern defining a plurality of pores, and is formed, at least in part, by warp knitting or weft knitting. At least some of the pore can be non-square in shape, including a triangular shape. The pores can be distributed across the knitted fabric filter media in a controlled, non-random manner. The knitted fabric filter media can include first and second layers of knitted fabric arranged to define a depth filter.
