NPPTL COVID-19 Response: International Respirator Assessment

Manufacturer: 3M

Model Tested: 1860

Date Tested: December 14, 2021

These findings pertain to the 3M, model 1860. The packaging and labeling indicate that it is a NIOSHapproved product, under approval number TC-84A-0006. 3M has indicated that this product is likely

counterfeit.

Twenty respirators were submitted for evaluation. The samples were tested using a modified version

of NIOSH Standard Test Procedure (STP) TEB-APR-STP-0059.

The maximum and minimum filter efficiency was 99.68% and 98.52%, respectively. All twenty

respirators measured more than 95% filter efficiency.

This product has head bands/straps. While filter efficiency shows how well the filter media performs,

users must ensure a proper fit is achieved.

This assessment is not a part of the NIOSH respirator approval process and will in no way lead to or

preclude NIOSH approval through the official approval process. This assessment was developed as an

assessment of the filter efficiency for those respirators represented as certified by an international

certification authority, other than NIOSH, to support the availability of respiratory protection to US

healthcare workers due to the respirator shortage associated with COVID-19. Only particulate filter

efficiency was assessed.

The results provided in this letter are specific to the subset of samples that were provided to NPPTL for

evaluation.

These results will be used to update the CDC guidance for Crisis Capacity Strategies (during known

shortages).

• The test method utilized in this assessment is not the NIOSH standard test procedure that is used for certification of

respirators. Respirators assessed to this modified test plan do not meet the requirements of STP-0059, and

therefore cannot be considered equivalent to N95 respirators that were tested to STP-0059.

• Respirators tested may not be representative of all respirators with the same certification mark. NIOSH has no

control over suppliers and distributors of respirators certified by other national or international parties.

• This assessment is not a confirmation that it conforms with any or all of its specifications in accordance with its

certification mark.

• This assessment was not a part of the NIOSH approval program. These results do not imply nor preclude a future

approval through the NIOSH respirator approval program.
