NOVELTY - A filter (2) has upper housing (20) including inlet (22) capable of receiving liquid propane gas, lower housing (26) attached to upper housing, inner assembly (28) having first and second ends, first filter element (42) between outer housing and inner assembly, and second filter element (48) contained within second filtration zone (40).    USE - The invention is used for removing contaminants from liquid propane gas (claimed).    DETAILED DESCRIPTION - The filter has upper housing including inlet capable of receiving liquid propane gas from upstream of filter and outlet (24) capable of conveying the gas downstream of the filter; lower housing attached to upper housing and communicating with the inlet; inner assembly having first and second ends and attached to upper housing and communicating at the first end with the outlet and being disposed within and spaced apart from the outer housing thus, defining a first filtration zone and second filtration zone; first filter element between the outer housing and inner assembly in the first filtration zone (38) and is comprised of liquid propane gas permeable enclosure (44) enclosing a molecular sieving agent (46); and second filter element contained within second filtration zone and comprised by porous filtration material (50) in which both filter elements communicate with each other at boundary between both filtration zones.    An INDEPENDENT CLAIM is also included for a method for removing contaminants from liquid propane gas comprising routing a flow of the gas through molecular sieving agent within first filter element to initialize removal of chemical contaminants from the gas; and subsequently routing the flow of the gas through the second filter element to remove particulate contaminants from the gas.
