This page provides information on face masks, barrier face coverings, surgical masks, and respirators (filtering facepiece respirators, such as N95 respirators) intended for a medical purpose to assist in preventing the spread of infectious materials during the COVID-19 pandemic.
This page does not cover:
- Powered respirators, such as powered air purifying respirators (PAPRs)
- Face shields
- Non-healthcare use of face masks and respirators intended to limit industrial or general exposure to non-infectious particles, such as during construction or other industrial use.
The information provided may be useful to manufacturers and importers of face masks, barrier face coverings, surgical masks, and respirators, as well as health care facilities and health care personnel.
To help expand the availability of face masks, barrier face coverings, surgical masks, and respirators, the FDA is providing certain regulatory flexibility for the duration of the COVID-19 public health emergency, as described in the Enforcement Policy for Face Masks and Respirators During the Coronavirus Disease (COVID-19) Public Health Emergency (Revised), and has issued emergency use authorizations (EUAs) for face masks, surgical masks, and respirators that meet certain criteria. The FDA regularly updates its communications about face masks, surgical masks, and respirators, including the answers to frequently asked questions on this page.

A: Face masks, barrier face coverings, surgical masks, and respirators all cover a wearer's nose and mouth, but they differ in several aspects.
- Face masks: A mask, with or without a face shield, that covers the user's nose and mouth and may or may not meet fluid barrier or filtration efficiency levels. Face masks should be used by the general public and health care personnel as source control in accordance with CDC recommendations on Interim Infection Prevention and Control, or in other situations as appropriate based on personal circumstances.
- Barrier face coverings: As described in ASTM F3502-21, a barrier face covering is a product worn on the face, specifically covering at least the wearer's nose and mouth, with the primary purpose of providing source control and to provide a degree of particulate filtration to reduce the amount of inhaled particulate matter.
- Surgical masks: A mask intended for medical purposes that covers the user's nose and mouth and provides a physical barrier to fluids and particulate materials. Surgical masks are Class II medical devices. These masks meet certain fluid barrier protection standards and flammability requirements (that is, Class I or Class II, per 16 CFR 1610.4). Surgical masks are also tested for particulate and bacterial filtration efficiencies and biocompatibility and are considered personal protective equipment (PPE). While surgical masks may be effective in blocking splashes and large-particle droplets, they do not provide a reliable level of protection from aerosolized particles because of the loose fit between the surface of the mask and your face. Surgical masks are not respiratory protective devices, such as respirators.
- Respirators: Air purifying respirators, known as respirators, including filtering facepiece respirators (FFRs) such as N95s and surgical N95s, filter at least 95 percent of airborne particles. They are PPE that tightly fit the face and provide certain filtration efficiency levels to help reduce wearer exposure to pathogenic particles in a health care setting. They provide a higher level of protection against viruses and bacteria when properly fit-tested.
This CDC infographic (PDF - 227KB) explains the differences between surgical masks and N95 respirators.
A: The FDA regulates face masks, including cloth face coverings, barrier face coverings, and surgical masks as medical devices when they are intended for a medical purpose. Medical purposes include uses related to helping prevent the spread of COVID-19. Face masks intended for use by the general public for non-medical purposes, such as for use in construction and other industrial applications, are not medical devices.
A: Face masks and barrier face coverings should generally be used for source control, meaning they may help prevent people who have COVID-19 from spreading the virus to others. These products may also help limit exposure to respiratory droplets and large particles but are not a substitute for filtering facepiece respirators or surgical masks. Please refer to CDC's webpage for recommendations regarding use and care of masks.
A: If worn properly, face masks, barrier face coverings, surgical masks, or respirators may reduce the chance of spreading a COVID-19 infection between you and those around you. The CDC provides information on How to Protect Yourself and Others, and Staying Up to Date with Your COVID-19 Vaccines.
FDA-cleared surgical masks and respirators have been used by health care personnel for years and have been worn in health care facilities during extended procedures without harm to the wearer. Health care personnel with medical conditions should discuss concerns they may have with wearing respirators with their own health care providers. Health care personnel should follow the manufacturer's instructions and their facility's policies for use of all PPE.
A: Source control refers to a person's use of barrier face coverings or face masks, including cloth face coverings, to cover the person's mouth and nose when they are talking, sneezing, or coughing to reduce the likelihood of transmission of infection by preventing the spread of respiratory secretions and large particles. COVID-19 may be spread by individuals who may or may not have symptoms of COVID-19.
The general public's use of cloth face coverings made from common, easily accessible materials, are an additional public health approach to help slow the spread of COVID-19. The CDC has information on Types of Masks and Respirators for the general public.
Barrier face coverings and face masks, including cloth face coverings, intended for a medical purpose, such as prevention of infectious disease transmission, are subject to FDA regulation. The FDA has issued a policy of regulatory flexibility for such products, as well as an emergency use authorization (EUA) for face masks. For more information, see "I'm interested in manufacturing face masks or surgical masks for the COVID-19 pandemic. What do I need to do?"
For more information on source control, see the CDC's Interim Infection Prevention and Control Recommendations for Healthcare Personnel During the Coronavirus Disease 2019 (COVID-19) Pandemic.
A:The CDC provides information on infection control measures for COVID-19, including: Clinical Questions about COVID-19: Questions and Answers, Types of Masks and Respirators, and Infection Control: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
A: The FDA provides information on medical device shortages during the COVID-19 public health emergency.
The FDA is interested in hearing from health care facilities and other stakeholders about shortages and potential shortages they may be experiencing. You may email the FDA at firstname.lastname@example.org.
A: The manufacturer-designated shelf life or expiration date may be found on the product labeling or packaging, or you can contact the manufacturer directly.
A: The CDC recommends reusable face masks be washed after each use and provides information on the washing of cloth face masks.
The reuse of barrier face coverings should be determined based upon the manufacturer's instructions, which may include washing and subsequent wear.
The user should inspect all masks prior to use and, if there are concerns such as degraded materials (such as elastic) or visible tears, the product should be discarded.
A: The FDA realizes that stakeholders such as health care facilities and states may continue to have a supply of non-NIOSH-approved FFRs that were authorized prior to FDA's July 6, 2021 revocation of both EUAs concerning non-NIOSH-approved FFRs. The Enforcement Policy for Face Masks, Barrier Face Coverings, Face Shields, Surgical Masks, and Respirators During the Coronavirus Disease (COVID-19) Public Health Emergency (Revised) explains that the FDA generally does not intend to object, for the duration of the public health emergency, to the further distribution and use of existing stockpiles of non-NIOSH-approved disposable FFRs for use as face masks for source control by the general public and HCP without compliance with certain regulatory requirements, where such use does not create an undue risk in light of the public health emergency. More information is included in the guidance.
A: EUAs authorize the emergency use of unapproved medical devices. The EUA authority allows the FDA to help strengthen the nation's public health protections against emerging infectious disease threats by facilitating the availability and use of medical devices needed during public health emergencies.
Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), the FDA Commissioner may authorize the emergency use of an unapproved or uncleared medical product or an unapproved / uncleared use of an approved/cleared medical product for certain emergency circumstances after the HHS Secretary has made a declaration of emergency or threat justifying emergency use. The FDA Commissioner may issue an EUA to authorize a medical product for use in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions when there are no adequate, approved, or available alternatives when certain criteria for issuance are met. The Emergency Use Authorizations (EUAs) for diagnostic, non-diagnostic, and therapeutic medical devices that the FDA has issued related to COVID-19 may be revised, terminated, or revoked as appropriate.
For details on the Emergency Use Authorizations for these devices, see:
If you need help with the EUA process for face masks, surgical masks, or respirators, contact CDRH-NonDiagnosticEUA-Templates@fda.hhs.gov.
To identify FDA-cleared surgical masks and respirators, search the 510(k) Premarket Notification database.
A: To help prepare for potential and current emergencies, the FDA works with medical device developers to prepare pre-EUA packages when appropriate. A pre-EUA package contains data and information about the safety, quality, and effectiveness of the product, its intended use, and information about the emergency or potential emergency. The pre-EUA process allows the FDA's scientific and technical subject matter experts to begin a review of information and consideration of the EUA statutory criteria, assist in the development of conditions of authorization, fact sheets, and other documentation that would be needed for an EUA, and also helps to facilitate completion of EUA requests during a current emergency declaration.
If you need help with the pre-EUA process for face masks, surgical masks, or respirators, contact CDRH-NonDiagnosticEUA-Templates@fda.hhs.gov.
For additional information, refer to Emergency Use Authorization of Medical Products and Related Authorities.
A: Many EUAs apply only to a specific medical device. Generally, an umbrella EUA authorizes many devices that meet specific criteria for that device type, helping to facilitate access to those devices by streamlining the process associated with EUAs (for example, EUA request submission and FDA authorization) for any medical devices that meet the requirements within the EUA.
A: The FDA issued an umbrella EUA in response to insufficient availability of disposable, single-use surgical masks. Surgical masks within the Scope of Authorization of this EUA are authorized for emergency use in health care settings by health care personnel as PPE.
The Scope of Authorization includes performance metrics that must be met including liquid barrier performance, particulate filtration efficiency, air flow resistance, and use of biocompatible, non-cytotoxic, non-irritating, and non-sensitizing materials. Surgical masks that have been confirmed by the FDA to be within the Scope of Authorization are listed in Appendix A of the EUA as authorized surgical masks.
To be added to Appendix A, test reports must be submitted to the FDA demonstrating that the surgical mask meets the performance criteria. Requests can be submitted to the FDA with the subject line "Surgical Masks EUA" to CDRH-nondiagnosticEUAemail@example.com. The Surgical Masks EUA Template for Addition to Appendix A (DOCX - 56KB) can be used to provide the required information.
Manufacturers, importers, and distributors must also comply with the conditions of authorization found in Section IV of the EUA Letter of Authorization (PDF - 101KB).
The following surgical masks are not within the scope of this EUA:
- Surgical masks that are FDA-cleared
- Surgical masks that are manufactured in China
- Surgical masks that include drugs, biologics, nanoparticles, or antimicrobial/antiviral agents
A: The removal of a product code from the device shortages list does not impact the existing Enforcement Policy for Face Masks, Barrier Face Coverings, Face Shields, Surgical Masks, and Respirators During the Coronavirus Disease (COVID-19) Public Health Emergency, Umbrella EUA for surgical masks, or NIOSH-Approved Air Purifying Respirators for Use in Health Care Settings During Response to the COVID-19 Public Health Emergency at this time. The policy and EUAs remain in effect at this time.
A: Respirators authorized by this EUA (PDF - 176KB) include:
- Non-powered air-purifying particulate FFRs and reusable respirators such as elastomeric half and full facepiece respirators, approved by NIOSH in accordance with 42 CFR Part 84 and listed on the NIOSH Certified Equipment list (CEL) for non-powered air purifying respirators with particulate protection; and
- Other powered air purifying respirators (PAPRs) approved by NIOSH, in accordance with 42 CFR Part 84, and that are listed on the NIOSH CEL for PAPRs with particulate protection
A: Manufacturers must submit marketing applications under the traditional premarket pathways in order to continue marketing their products if the applicable emergency use authorization is revoked.
Device manufacturers are encouraged to pursue marketing applications through the appropriate regulatory pathway (such as 510(k), De Novo request, or PMA) during the emergency so that devices can remain on the market once the EUA is no longer in effect. For more information, see FAQs on Emergency Use Authorizations (EUAs) for Medical Devices During the COVID-19 Pandemic.
The FDA issued two draft guidances: Transition Plan for Medical Devices Issued Emergency Use Authorizations (EUAs) During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency as well as Transition Plan for Medical Devices That Fall Within Enforcement Policies Issued During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency. Although these draft guidances are not for implementation at this time, manufacturers are encouraged to pursue any required marketing submissions through the appropriate regulatory pathway (for example, 510(k), De Novo, PMA) during the public health emergency if they plan to continue distribution after the public health emergency ends or the relevant EUA declaration is terminated.
Manufacturing and Importing Face Masks, Barrier Face Coverings, Surgical Masks, and Respirators During the COVID-19 Pandemic
A: Face masks and barrier face coverings intended for a medical purpose, such as prevention of infectious disease transmission, are subject to FDA regulation. The FDA has issued guidance on regulatory flexibility for such products, as well as EUAs for face masks and surgical masks.
The guidance provides an enforcement discretion policy for face masks and barrier face coverings intended for a medical purpose for use during the COVID-19 public health emergency, such as for use as source control.
Face masks, intended for use by health care personnel and the general public as source control to help stop the spread, may be authorized under the umbrella EUA for face masks (PDF - 92KB) without submitting documentation to the FDA if the face mask is within the Scope of the EUA. A face mask authorized under this EUA must comply with the Conditions of Authorization (Section IV) of the EUA.
For a surgical mask to be added to the Surgical Mask EUA Appendix A, test reports must be submitted to the FDA demonstrating that the surgical mask meets the performance criteria for liquid barrier protection. Requests can be submitted to the FDA with the subject line "Surgical Masks EUA" to CDRH-nondiagnosticEUAfirstname.lastname@example.org. The Surgical Masks EUA Template for Addition to Appendix A (PDF - 176KB) can be used to provide the required information.
Manufacturers, importers, and distributors of surgical masks must also comply with the conditions of authorization found in Section IV of the EUA Letter of Authorization (PDF - 101KB).
The following surgical masks are not covered in the scope of this EUA:
- Surgical masks that are FDA-cleared
- Surgical masks that are manufactured in China
- Surgical masks that include drugs, biologics, nanoparticles, or antimicrobial/antiviral agents.
A: Respirators require NIOSH approval. Once NIOSH approval is obtained, the respirator is authorized under the EUA for NIOSH-approved air-purifying respirators (PDF - 176KB). In some cases (for example, if the respirator claims to prevent specific diseases or infection, or if it includes antimicrobials or other additives), obtaining FDA clearance may be the appropriate pathway (see 21 CFR 878.4040).
Additional information is available in the Manufacturing and Distributing Respirators for Health Care Use in the United States Under an Existing Emergency Use Authorization (EUA) During the COVID-19 Pandemic flowchart.
A: The Enforcement Policy for Face Masks, Barrier Face Coverings, Face Shields, Surgical Masks, and Respirators During the Coronavirus Disease (COVID-19) Public Health Emergency provides guidance on manufacturing or importing face masks, barrier face coverings, surgical masks, and respirators.
