A fluid filter apparatus includes a first surrounding sidewall, a co-axial second surrounding sidewall, a co-axial third surrounding sidewall, and a co-axial fourth surrounding sidewall, an outer annulus as between the first and third surrounding sidewalls, and a domed end on the fourth sidewall, wherein a first interior is formed between the second and the fourth sidewalls. Also, a ported head body that includes two pairs of opposing inlet and outlet apertures and inlet and outlet chambers, wherein the body is adjacent to the first and third sidewalls and a filter media disposed within the first sidewall. Operationally, a dirty fluid enters therethrough the inlet aperture to the inlet chamber into the outer annulus, to the first interior, and through the dome and communicates onward therethrough the filter media and outward to the outlet chamber and to the outlet aperture.
