wherein the selectable media filter and sparger assembly is fabricated at least in part by additive manufacturing;
wherein the housing is a single housing;
wherein the housing has a solid housing cap;
wherein the plurality of porous members are fabricated with different pore structures and/or densities relative to each other for a flow to pass therethrough at different rates; and
wherein the plurality of porous members are fabricated at least in part from a metal.
2 . The assembly of claim 1 further comprising a support member extending from the housing.
3 . The assembly of claim 2 , wherein the support member is a solid center support member extending from the housing.

6 . The assembly of claim 1 , wherein each connection port is configured to accept a fitting for filtrate removal or supply gas or liquid.
7 . A system, comprising:
a reaction vessel,
the assembly of claim 1 , wherein in operation, one or more of the connection ports is configured for being fluidly coupled to a supply of nitrogen while another one or more of the connection ports is configured for being fluidly coupled to a supply of oxygen, to thereby obtain a predetermined level of oxygen depletion and saturation within the reaction vessel.
8 . A method of fabricating the selectable media filter and sparger assembly of claim 1 , the method comprising:
providing the plurality of porous members attached to the housing;
wherein each of the plurality of porous members is fluidly coupled to one connection port of the plurality of connection ports; and
wherein the selectable media filter and sparger assembly is fabricated at least in part by additive manufacturing.
9 . The method of claim 8 , wherein the selectable media filter and sparger assembly is fabricated at least in part by a 3 D printing process.
10 . The method of claim 8 , wherein the selectable media filter and sparger assembly is fabricated at least in part by a laser powder bed fusion (LPBF) process.
11 . The method of claim 8 , wherein the selectable media filter and sparger assembly is fabricated at least in part by an electron-beam melting (“EBM”) process.
12 . The method of claim 8 , wherein the selectable media filter and sparger assembly is fabricated at least in part by an inkjet or a binder-jet additive manufacturing process.
13 . A system, comprising:
a reaction vessel,
the assembly of claim 1 , wherein pore structures of the porous members differ from each other, and

wherein the pore structures of the porous members fluidly coupled to the supply of oxygen is smaller than the pore structures of the porous members fluidly coupled to the supply of carbon dioxide,
to thereby control a mass transfer rate of the carbon dioxide and oxygen in the reaction vessel.
14 . The assembly of claim 1 , wherein a cross section of the porous members is non-circular.
15 . The assembly of claim 1 , wherein a cross section of the porous members is circular.
16 . A selectable media filter and sparger assembly comprising:
