The below summaries and actual results are all based on testing the Copperline Mask with the HEPA filter attached (unless specified)

Testing conducted WITHOUT the HEPA filter achieved a filtration rate of 92.3% laboratory conditions. 

Note that the active copper is contained within the Copperline Mask and not in the HEPA filter.
