NPPTL COVID-19 Response: International Respirator Assessment

Manufacturer: Advoque

Model Tested: ADV001

Date Tested: August 28, 2020

These findings pertain to the Advoque, model ADV001. The labeling indicates that it is a NIOSHapproved product, under approval number TC-84A-PH02.

Ten respirators were submitted for evaluation. The samples were tested using the modified version of 

NIOSH Standard Test Procedure (STP) TEB-APR-STP-0059. This modified assessment plan can be found 

here. 

The maximum and minimum filter efficiency was 93.08% and 89.84%, respectively. All ten respirators 

measured less 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.
