A True HEPA filtration device or filter is the only type of HEPA filter that truly conforms to the DOE standard for HEPA filtration, has the highest efficiency, and hits the 99.97% threshold. If the HEPA filter does not meet the DOE's standards for HEPA filtration, then it is not considered True HEPA.
