摘要： A filter for a liquid spraying device such as an airless paint sprayer. The filter separates unwanted foreign material and clumps from a liquid before the liquid is pumped into a liquid spraying device. The filter is removably mounted on a hose of a liquid spraying device to filter the liquid as it is extracted into the hose. The filter has a frusto-conical surface member having a hollow cavity, a top surface, and an open base terminating at an annular wall around the perimeter of the base. A plurality of holes surround the surface of the frusto-conical surface member wherein the holes are formed at an angle of about 90.degree. to a plane spanning the base. Removably attached to the annular wall is a circular disk having a planar surface terminating at a ring such that the ring projects about perpendicularly from the planar surface. The circular disk has a coupling projecting about perpendicularly around a center point of the planar surface.
