People must wear masks that completely cover the mouth and nose. Masks should fit snugly against the sides of the face. See CDC’s guidance for attributes of masks needed to fulfill the requirements of the Order.
What type of mask is recommended to prevent the spread of COVID-19?
CDC recommends community use of masks, specifically non-valved, multi-layer cloth masks, to prevent transmission of SARS-CoV-2.
Should I use a surgical masks or N95 respirators to protect against COVID-19?
No. Surgical masks and N95s need to be reserved for use by health care workers, first responders, and other frontline workers whose jobs put them at much greater risk of acquiring COVID-19. The cloth face coverings recommended by CDC are not surgical masks or N95 respirators. Surgical masks and N95s are critical supplies that must continue to be reserved for health care workers and other medical first responders, as recommended by CDC.
How effective are different material face masks during the COVID-19 pandemic?
They found that the effectiveness of the masks varied widely: a three-layer knitted cotton mask blocked an average of 26.5 percent of particles in the chamber, while a washed, two-layer woven nylon mask with a filter insert and metal nose bridge blocked 79 percent of particles on average.
Does a surgical mask help avoid COVID-19?
If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.
What types of masks are most and least effective at preventing the spread of COVID-19?
If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.
How do cloth face coverings and face shields protect against COVID-19?
Cloth face coverings and face shields are types of source control that provide a barrier between droplets produced from a potentially infected person and other people, reducing the likelihood of transmitting the virus.
What is a COVID-19 N95 respirator?
Cloth face coverings and face shields are types of source control that provide a barrier between droplets produced from a potentially infected person and other people, reducing the likelihood of transmitting the virus.
Will a N95 filtering facepiece respirator mask protect me from COVID-19?
Yes, an N95 filtering facepiece respirator will protect you and provide source control to protect others. A NIOSH-approved N95 filtering facepiece respirator with an exhalation valve offers the same protection to the wearer as one that does not have a valve.
How can I tell if the face masks, surgical masks, or respirators I want to purchase during the COVID-19 pandemic are counterfeit or fraudulent?
The FDA does not have a list of all counterfeit or fraudulent products. To report fraudulent COVID-19 products to the FDA, email [email protected]. The CDC provides information on identifying counterfeit respirators at Counterfeit Respirators / Misrepresentation of NIOSH-Approval.

Can I use a polyester mask during the COVID-19 pandemic?
Polyester or other less breathable fabric will not work as well, due to moisture produced when breathing. If using denim or other fabric that is being “recycled”, please be sure it is clean and in good shape. Worn or dirty fabric will not be protective.
Are cloth face coverings the same as personal protective equipment (PPE)?
Polyester or other less breathable fabric will not work as well, due to moisture produced when breathing. If using denim or other fabric that is being “recycled”, please be sure it is clean and in good shape. Worn or dirty fabric will not be protective.
Are multilayer cloth masks more effective than single-layer ones for protecting from COVID-19?
In recent laboratory experiments, multilayer cloth masks were more effective than single-layer masks, blocking as much as 50% to 70% of exhaled small droplets and particles.
Should one wear a surgical mask?
In recent laboratory experiments, multilayer cloth masks were more effective than single-layer masks, blocking as much as 50% to 70% of exhaled small droplets and particles.
Who do masks protect from COVID-19: the wearer, others, or both?
In recent laboratory experiments, multilayer cloth masks were more effective than single-layer masks, blocking as much as 50% to 70% of exhaled small droplets and particles.
Does wearing a cloth mask over a medical one reduce exposure to COVID-19 more than wearing just one mask?
Based on experiments that measured the filtration efficiencies of various cloth masks and a medical procedure mask (6), it was estimated that the better fit achieved by combining these two mask types, specifically a cloth mask over a medical procedure mask, could reduce a wearer’s exposure by >,90%.
