Electromagnetic Filter

&nbsp The Electromagnetic Filter was an air filter system built by Ben to filter out harmful particles in the air including mould, dust and contagions It was built with the purpose to clear dirty air in the SGC when it was discovered it had no ventilation system (Month 0.5).

Principal of Working
Dirty air flows into the filter, via a fan or compressor, then runs through a series of charged meshes.The aire (now charged) runs through a much finer mesh and a layer of steel wool. The air then flows out, now clean.

Flaws in Design
The filters must be replaced every 3-5 weeks
