A filter holding assembly capable of being used to filter pressurized fluid from a source of the latter, with the assembly capable of being dismantled without the use of hand tools to occupy a minimum of space, and the assembly likewise capable of being transformed without the use of hand tools to a unit in which first and second mating plates support a large diameter filter membrane in a position to be subjected to the pressurized fluid. Particulates in the fluid above a predetermined size are deposited on the membrane, with the balance of the fluid discharging as a filtrate from the assembly. The first and second plates when in mating engagement define a centered confined space in which the membrane and a supporting screen are disposed, and the membrane having the peripheral edge portion thereof in sealing contact with a compressed resilient ring to prevent the pressurized fluid in the centered confined space by-passing the membrane. The filter assembly is particularly adapted for use with a second filter assembly that is supported therefrom, with the large diameter first membrane effecting a primary filtration in which particulates above a predetermined size are removed from the fluid, and the resulting filtrate when subjected to a finer filtration by the second assembly to remove particulates above a predetermined size that have passed through the first membrane.
