Filtering Facepiece 
Respirator Certification 



• 431 filtering facepiece respirator approvals 
granted to 37 different companies 

- This does not include the filtering facepiece 
approvals that have been rescinded or revoked. 

- Of these 431 approvals, 25 of them are obsolete 

• Current FFR Certification testing 



- Breathing resistance 

- Filter efficiency

Requirements 



F unctionality 

•Protect 
against 
influenza virus 
•Guard 

against contact 
with 

contaminated 
fluids and 
aerosols

Usability 



• Maintain biomechanics! efficiency 
and sense of touch and feel 

• Odor free 

• Hypoallergenic 

• Accommodate wide range of users 
(face and body profiles) 

• Compatibility across various 
elements of the PPE ensemble and with 
other equipment (e.g., stethoscope) 

• Non-startling to patients and 
families 

• F acilitate communication with 
others (verbal, facial) 



Maintenance and 
and Reuse 

• Easy to 

decontaminate and 
discard disposable 
elements 

• Easy to clean and 
replace parts in 
reusable PPE 



C omfortand Wearability 

• Comfortable— no skin irritation 
or pressure points 

• Prolonged use without 
discomfort 

• Breathable- air permeable 

• M oisture absorbent- wickability 

• Low bulk and weight 

• Dimensional stability 

• Easy to put on and take off (don 
and doff) 



Aesthetics 

• Variety of 
styles and colors 

• Customizable 



Cost 

• Product cost 

• Total life-cycle 
cost 

• Minimal 
environmental 
impact 



Durability 

• Adequate wear 
life 

• Strength— tear, 
tensile, burst 

• Abrasion 
resistance 

• Corrosion 
resistance

Breakout Session 1: Question 1 

What are the differences among the various styles of FFRs 

relative to a) protection, b) comfort, c) usability, d) maintenance, 

e) reuse, f) durability, g) cost? 




Respirator Attributes and Comparative Analysis 


Compare the differenttypes of FFRs and masks with respect to the various attributes on a 1, 5, 10 
scale 


A =Always(10), S = Sometimes (5), N =Never(0)
