The Centers for Disease Control and Prevention is expected to reverse its recommendation on wearing face masks — including cloth masks sewn at home — to suggest that individuals wear coverings in public in addition to taking measures like.
The White House could announce the new guidelines, based on the CDC’s evaluation. But during a press conference Thursday, President Trump suggested that the CDC will issue the new guideline itself, and soon. “A recommendation is coming out. We’ll see what that recommendation is,” he said.
The CDC is the US authority on coronavirus protocols and protection to, the disease caused by the coronavirus. The CDC did not respond to multiple requests for comment.
New York City and Los Angeles are now advocating the use of face coverings in public. “We’re advising New Yorkers to wear a face covering when you go outside and will be near other people,” said New York Mayor Bill de Blasio in a public address.
For weeks, the debate has escalated over whether homemade face masks should be used in hospital settings and also by individuals in public. It comes at a time when available stock of certified— the essential protective equipment used by health care workers fighting the — has reached critical lows.
Until now, the CDC has considered homemade face masks to be used as a last resort in hospitals and medical facilities. Masks made from cotton and elastic certainly won’t harm civilians at home or when going out, as long as you’re also following .
The US Surgeon General, Vice Admiral Jerome M. Adams, tweeted on Wednesday that his office asked the CDC if its recommendations on face mask use should change in light of new data. Adams stressed that wearing a mask should not supersede social distancing.
The Surgeon General also tweeted that the shortage of , plays a vital role in exploring new recommendations for face mask use, citing that “most public health officials and scientists agreed that healthy people shouldn’t wear masks.”
In a medical setting, handmade masks aren’t scientifically proven to be as effective at protecting you from the coronavirus. Why not? The answer comes down to the way N95 masks are made, certified and worn. It may not matter if care centers are forced to take a “better than nothing” approach.

Global leaders and medical professionals ask that you please not buy N95 masks for yourself, so as to save them for the medical community that’s in desperate need. For example, Target has apologized for selling N95 masks amid the shortage.
If you do have a supply of N95 masks on hand, consider donating them to a health care facility or hospital near you. Here’s how toto hospitals in need — and why you should also .
Here’s everything you need to know about the difference between homemade face masks and N95 respirator masks.
N95 masks fit to your face and go through certification
N95 respirator masks differ from other types of surgical masks and face masks because they create a tight seal between the respirator and your face, which helps filter at least 95% of airborne particulates. They might include an exhalation valve to make it easier to breathe while wearing them. and be transmitted from person to person through vapor (breath), coughing, sneezing, saliva and transfer over commonly touched objects.
Each model of N95 mask from each manufacturer is certified by the National Institute for Occupational Safety and Health. N95 surgical respirator masks go through a secondary clearance by the Food and Drug Administration for use in surgery — they better protect practitioners from exposure to substances such as patients’ blood.
In US health care settings, N95 masks must also go through a mandatory fit test using a protocol set by OSHA, the Occupational Safety and Health Administration, before use. This video (linked) from manufacturer 3M shows some of the key differences between standard surgical masks and N95 masks.
Homemade masks are unregulated.
Who handmade masks are for
As it stands now, hospitals and medical centers are taking nontraditional steps to resupply their stock, asking for community donations of items like N95 masks, protective goggles and nitrile gloves. Some that do request hand-sewn masks note that donated masks will go to worried patients and nonclinical staff, not physicians and nurses — but that might be changing depending on the hospital and state of need.
Protective equipment is in such short supply at other hospitals and medical care centers that they’re now driven to use surgical masks or other masks if there’s no other option — and only during COVID-19 conditions. Some health centers suggest their preferred patterns and request that masks have four layers of fabric to better block out particulates. In these cases, personnel are asked to maintain a high level of caution (more on this in the CDC section below).
Harvard Medical School Teaching Hospital and the Boston Children’s Hospital shared a joint video about making a homemade reusable respirator mask in response to the current shortage. However, the design is currently limited to a pilot program and is not certified for official use, though it’s certainly available for use. Here’s the legal disclaimer:

Handmade masks: Cotton and elastic
The DIY homemade face mask movement that’s providing patterns and instructions for sewing face masks at home tell you to use materials like multiple layers of cotton, elastic bands and ordinary thread.
By and large, the patterns contain simple folds with elastic straps to fit over your ears. Some are more contoured to resemble the shape of N95 masks. Still others contain pockets where you can add “filter media” that you can purchase elsewhere.
It’s the belief of people who make their own masks that adding filters will help protect against transmission. Be aware that there isn’t strong scientific evidence that the masks will conform to the face tightly enough to form a strong seal, or that the filter material inside will work effectively. Standard surgical masks, for example, are known to leave gaps.
Homemade masks weren’t originally intended to protect you from COVID-19
Many sites sharing patterns and instructions for homemade masks were created as a fashionable way to keep the wearer from breathing in large particles, like car exhaust, air pollution and pollen during allergy season. They were not conceived of as a way to protect you from acquiring COVID-19.
One site, CraftPassion, includes this disclaimer:
Due to recent coronavirus attacks across the world, I have been receiving a lot of requests on how to add nonwoven filter inside the face mask. Disclaimer: this face mask is not meant to replace the surgical face mask, it is a contingency plan for those who have no avail to surgical mask in the market. Proper use of a surgical mask is still the best way to prevent virus infection.
Centers for Disease Control and Prevention’s stance on homemade masks
Along with the World Health Organization, the CDC is the authoritative body that sets guidelines for the medical community to follow. The CDC’s position on homemade masks might change — we’ve reached out for more information.
Acknowledging a shortage of N95 masks, one page on the CDC website suggests five alternatives if a health care provider, or HCP, doesn’t have access to an N95 mask.
In settings where face masks are not available, HCP might use homemade masks (e.g., bandana, scarf) for care of patients with COVID-19 as a last resort [our emphasis]. However, homemade masks are not considered, since their capability to protect HCP is unknown. Caution should be exercised when considering this option. Homemade masks should ideally be used in combination with a face shield that covers the entire front (that extends to the chin or below) and sides of the face.
A different page on the CDC site appears to make an exception, however, for conditions where no N95 masks are available, including homemade masks.
HCP use of non-NIOSH approved masks or homemade masks
In settings where N95 respirators are so limited that routinely practiced standards of care for wearing N95 respirators and equivalent or higher level of protection respirators are no longer possible, and surgical masks are not available, as a last resort, it may be necessary for HCP to use masks that have never been evaluated or approved by NIOSH or homemade masks. It may be considered to use these masks for care of patients with COVID-19, tuberculosis, measles, and varicella. However, caution should be exercised when considering this option.
Homemade masks aren’t sterilized
Another difference between homemade masks and factory-made masks from brands like 3M, Kimberly-Clark and Prestige Ameritech have to do with sterilization, which is crucial in hospital settings. With handmade face masks, there’s no guarantee the mask is sterile or free from an environment with coronavirus — however, measures like washing the masks might help combat that.
CDC guidelines considers N95 masks contaminated after each single use and recommend discarding them. However, the severe shortage of N95 masks has caused many hospitals to take extreme measures in an attempt to protect doctors and nurses, like attempting to decontaminate masks between use. One medical center in Nebraska, for example, is experimenting with ultraviolet light treatments to sterilize N95 masks.
The danger: Not knowing the limits
If you want to make your own face masks for personal use because it provides you peace of mind, there’s no harm in that. What’s important to understand, however, is that sewing your own face mask may not prevent you from acquiring coronavirus, especially if you’re also engaged in risky behavior like lingering in crowded places or continuing to meet up with friends.
Since the coronavirus can be transmitted from someone who appears to be symptom-free but actually harbors the virus, it’s crucial to the health and wellness of people over 65 and those with underlying conditions to know which proven measures will help keep everyone safe.
