A dual filtering apparatus for filtering and purifying contaminated oil used in a deep-fat frying vat, comprising: a tub; a remote filtering screen attached to the tub by a external conduit through which the oil is conveyed from the frying vat, the remote filtering screen being adapted for placement in the vat and providing partial filtering of the oil before it is conveyed to the tub; a fine filtering assembly carried by the tub and comprising a generally cylindrical canister having a cap covering the canister on its top, the cap having an annular depending skirt that fits into the interior of the canister; a central conduit through a portion of the canister and in fluid communicating relationship with the tub; a perforated, lower retainer plate disposed around the central conduit and forming together with a bottom and side walls of the cannister a lower sediment area; a perforated upper retainer plate disposed around the central conduit forming together with the cap an upper void area, the central conduit being in fluid communicating relationship with the upper void area; a fine filter means mounted in surrounding relationship to the central conduit between the lower and upper plates, upward displacement of the filter means being prevented by the upper plate which is held against the fine filter means by the depending skirt of the cap; an inlet conduit through the bottom of the canister through which partially filtered oil is conveyed from the external conduit to the lower sediment area and through the fine filter means; an overflow conduit through the bottom of the canister, the conduit being provided with a pressure relief valve which opens in response to an increase of pressure in the lower sediment area; a means for drawing oil through the external conduit and forcing it into the inlet conduit, through the fine filter means, into the central conduit and thence to the tub; means for drawing oil from the tub and expelling it through the external conduit into the vat.
