CleanShield Washable Antimicrobial 5 Layer Premium Face Masks LABORATORY TEST RESULT SUMMARIES

Official Laboratory Reports

The particle filtration efficiency of CleanShield washable face masks have been fully tested by the Danish Technological Institute using a DEHS1 aerosol test utilizing a SMPS measuring system resulting in a particle capture concentration and size distribution in the range from 7 Nm to 673 Nm (Covid-19 particles are around 60-149 Nm – ref: WHO).

Further testing of the effectiveness of the masks to remove particles was measured before and after hand washing using 30 °C and 40 °C water. The results did not alter the capability of the mask filtering system. Additional hand wash testing (washing the masks) was conducted between 15 times at 40 °C. The results proved only a slight (<1-2%) degradation in the efficiency of the masks to continue to remove particles under the same aerosol testing.

Washing either by hand or using 30 °C or 40 °C water did not appear to alter the efficiency. Also, we could not document a change in efficiency after washing fifteen times at 40 °C.

Aug 2020: Recent laboratory testing of the CleanShield unique mask surface coating technology confirms that the mask will continuously decomposes and kills bacteria and viruses when exposed to a light source (natural or artificial).

Summary to confirm mask surface:

  • ISO 22196:2011
  • ISO 20743:2013

Based on antimicrobial test results CleanShield Face Mask shows very strong and long term antimicrobial activity with almost 100% antimicrobial effect. Based on our best knowledge and in accordance with previous tests CleanShield Face Mask surface acts also effectively against viruses and other organic specimens and pollutant.

Aug 2020: Updated laboratory EN/CE testing of the CleanShield face mask "Conformity Assessment" is listed as:
