I know this may sound stupid but I was told of a method of filtration that uses layers of tissue paper as the filter medium. It is not for the speedy. The Oil on the tissue stops it breaking up. The method involved gravity of the oil mass to filter through the tissue layers which may be an inexpensive first filter requiring no energy to use. The larger the area of paper the faster the filtation. The method was shown on TV as a way of re-using cooking oil. The resultant oil was said to be clear and particle free.A small amount of heat may speed up the filtration.
