Filter system and method

A method comprising:

• directing a fluid having particles through a body from an inlet toward an outlet fluidly coupled with the inlet by one or more passageways within the body, the one or more passageways configured to rotate the fluid in one or more cyclonic directions between the inlet and the outlet;
• and
• directing the fluid through a lattice component having one or more openings, the fluid configured to move through the one or more openings in the one or more cyclonic directions within the body from the inlet toward the outlet,
• the one or more passageways shaped to remove a first portion of the particles from the fluid, and the lattice component shaped to remove a second portion of the particles from the fluid such that the fluid exiting from the body via the outlet has fewer of the particles than when the fluid entered the body via the inlet.

A filter system comprising:

• a body comprising an inlet and an outlet fluidly coupled with the inlet by one or more passageways within the body, the one or more passageways shaped to direct a fluid having particles through the body from the inlet toward the outlet, the one or more passageways configured to rotate the fluid in one or more cyclonic directions between the inlet and the outlet;
• and
• a lattice component disposed within the one or more passageways, the lattice component having plural lattice walls defining one or more openings through which the fluid passes as the fluid moves in the one or more cyclonic directions within the body from the inlet to the outlet, the plural lattice walls being shaped to control a size of the one or more openings between consecutive lattice walls of the plural lattice walls,
• the one or more passageways shaped to remove a first portion of the particles from the fluid, and the lattice component shaped to remove a second portion of the particles from the fluid such that the fluid exiting from the body via the outlet has fewer of the particles than when the fluid entered the body via the inlet, wherein the one or more passageways and the lattice component are configured to remove at least 95% of the particles from the fluid such that the fluid exiting the outlet contains no more than 5% of the particles relative to the fluid entering the inlet.
