KandyMask Testing and Certification
We have been researching filtration for face masks and air purifiers since 2008. We have learned how to develop great filtration products over the years. Being open and transparent about testing and performance is at the core of what we do.
We know how important it is for you to buy a face mask that offers absolute respiratory protection. In our world, performance needs to be backed by data and not fancy marketing jargon.
Nelson Labs performed these tests and is the world leader in microbiological and analytical laboratory tests. They also serve the pre-qualification testing for NIOSH, which certifies N95 masks. They are the gold standard when it comes to medical and pharmaceutical testing. Below is a summary of our face mask filter test results.

KandyMask - Summary of Face Mask Filter Test Results
PFE Test Report
This test is performed to determine the particle penetration rate of the filters. Sodium Chloride (NaCI) is generated and pushed through the entirety of the face mask. Sodium Chloride is basically microscopic particles of salt. This allows scientists to replicate different size particles you would find in air pollution.
The Nelson Lab scientist used particle sizes between 0.075 microns and 0.3 microns. The mass medium size was around 0.26 microns. This size is chosen because it is the most penetrating and challenging size for a face mask filter to catch.
KandyMask is only intended as a means of source control in alignment with Regulatory considerations on the classification of non-medical masks: Notice to industry.
