Abstract: Filtration systems are described. In particular, a filtration system for filtering airborne particles includes an accumulation layer defining an intake surface and an exhaust surface, the accumulation layer defining an acute angle with a gravitational direction. The filtration system also includes a plurality of linear conduits included in the accumulation layer, the linear conduits being disposed in parallel with one another.
