If you actually do have oil in your heater clogging things up, it comes from the plasticizer used in most hoses, not from the tank of propane. Mr Buddy sells hoses both with and without the plasticizer. The 10' "green" one does not need the fuel filter, the 12' regular hose does.
"Response from Mr. Heater:
When you connect any of our Buddy model heaters to a remote propane tank, that tank can have over 120 PSI of pressure inside it.
This high pressure in the rubber hose connected to the heater can squeeze a plasticizer or an oil out of the rubber in the hose and once it gets into the heater it is trapped and will plug up the tubes and cause the heater to be an unreliable unit.
We came up with a fuel filter to prevent this oily substance from getting into the heater when using a high pressure hose.
The hose manufacturers came up with a hose that doesn't have the plasticizers in it so NO filter is needed (our part number for this plasticizer hose is F273704).
BUT the draw back with this hose is with no plasticizers in the rubber it causes the hose to be very stiff especially in cold weather. So you don't need the filter but you have to work with a hose that doesn't like to straighten out or is more difficult to work with because of this stiffness."
This is from the user reviews at Amazon for their green hose. Note in some of the other user reviews that the 'green' hose is now not actually green in color.
I have the non-plasticizer hose and so far have no problem with it being overly stiff, though have not used it yet in severe cold.
