During the Phase I Research Period we will develop a high porosity, nanoengineered filtration material that couples high filter efficiency with a very low pressure drop. The core innovation of the technology is the use of a novel nanostructured fill material that has a solidity 10 times lower than typical filter materials. The fill material is efficient at capturing particulates via interception, inertial impaction and electrostatic attraction but has an extremely low aerodynamic cross section. The low pressure drop per unit thickness allows for thicker filter substrates to be produced that have a high loading capacity, extending their effective filter lifetime performance.
