A filtration system for laser and three-dimensional (3D) printing fume and dust extraction includes a prefilter, a charging grid, and an electrostatic collection module. An inline filter box incorporating the filtration system is positioned between a laser or 3D printer and a main pollutant extraction system. The prefilter draws polluted air to remove large particles. The remaining smaller particles are made to go through the charging grid. At the charging grid, an electric field charges the particles and begins breakdown of chemical pollutant structure. Subsequently, the charged particles are made to pass into the electrostatic collection module. The charged particles are made to get attracted to the electrostatic surfaces of the electrostatic collection module resulting in very high removal of particles (over 95%), and destruction of germs and chemical pollutants.

A filter device provides designs that permit variable levels of solid particle removal. The filter device retains the particles in the filter medium when removed, thus avoiding the re-entry of the particles when the power system has cooled down which occurs in conventional filters currently in use. The filter device incorporates elements made from stainless steel for (a) durability and high mechanical strength to endure high continuous flow pressures; (b) ductility so as to be pleated and shaped into a cylinder; (c) corrosion and high temperature resistance; (d) particulate removal in the range of 4-20 microns depending on the desired performance characteristics; (e) high percentage of contaminant removal; and (f) recyclability and reusability.
