Non-medical masks are not considered effective in blocking small particles as the hard-to-obtainneeded by the medical community, but their advantage is that homemade face masks are readily available and can be help block larger particles emitted from talking, coughing, spitting, and sneezing.

Why now insist on homemade, non-medical face masks?
For months, the CDC advised medical face masks for people suspected or diagnosed with COVID-19 as well as for medical workers. However, many cases in the US and especially in hotspots such as New York, Rhode Island, Michigan, Louisiana and Arizona have proven that current measures are not strong enough to smooth the curve .
There is also data that it can be an advantage to wear a homemade mask in crowded places such as the supermarket, rather than no face covering at all. Social separation and hand washing are still paramount (more below).
Earlier this month, the chief physician of the American Lung Association, Dr. Albert Rizzo, this in an emailed statement:
The wearing of the masks by all individuals may provide some degree of barrier protection against respiratory droplets coughing or sneezing around them. Early reports show that the virus can live in a drop in the air for up to one to three hours after leaving an area. Covering your face prevents these droplets from entering the air and infecting others.
Homemade masks can help protect others from
According to the American Lung Association one in four people infected with COVID-19 may show mild symptoms or no symptoms at all. Using a fabric face cover when you are around others can help block large particles that you could eject from coughing, sneezing, or accidentally launched saliva (for example, by speaking), which would spread transmission to others may slow down if you don't know you're sick.
"These types of masks are not intended to protect the wearer but to protect against accidental transmission – if you are an asymptomatic carrier of the coronavirus," says the American Lung Association in a blog post discussing the wearing of homemade masks (emphasis on us).
What The CDC Says About Homemade Face Masks Today
The main takeaway from the CDC's message is that covering your faceis a "voluntary public health measure" and should not replace proven precautions such as at home, and .
The CDC is the US authority on protocols and protection againstthe disease caused by the coronavirus.
In the words of the CDC, it recommends "wearing cloth face covers in public environments where other social distance measures are difficult to maintain (for example, supermarkets and pharmacies).] in particular significant transfer from the community. "(Emphasis is on the CDCs.)
The institute says you should not seek medical or surgical masks yourself and that you shouldto health professionals leave, instead choose basic cloth or fabric coverings that can be washed and reused. Previously, the agency considered homemade face masks as a last resort in hospitals and medical institutions.

The Right Way to Wear a Face Covering or Fabric Face Mask
The important thing is to cover your entire nose and mouth, meaning the face mask should fit under your chin. The upholstery is less effective if you take it off your face when you're in a busy store, like talking to someone. For example, it is better to adjust your upholstery before you leave your car, rather than waiting in line at the supermarket. Read more about why fit is so important.
Can you reuse your face mask?
Homemade masks and coverings made of cloth fabric are machine washable. Medical grade masks are ideal for single use, although in certain hospital settings the severe shortage of N95 masks necessitates procedural exceptions. Here's what you need to know about.
The FDA has developed an emergency protocol for medical institutions to sterilize N95 masks – only for hospitals and medical institutions.
The amazing face mask debate
For weeks, there has been a debate about whether homemade face masks should be used in hospitals and also by individuals in public. It is at a time when the available supply of certified– the essential protective equipment used by health professionals fighting the coronavirus pandemic – has reached critical lows.
In a medical setting, handmade masks have not been scientifically proven to be equally effective in protecting you from the coronavirus. Why not? The answer comes down to how N95 masks are made, certified and worn. It may not matter if care centers are forced to follow a 'better than nothing' approach.

N95 Masks vs Other Masks: Facial Expression and Certification
N95 Masks are considered the Holy Grail of Face Coverage, and are considered by medical professions to be the most effective way to protect the wearer from acquisition. the coronavirus.
N95 masks differ from other types of surgical masks and face masks in that they create a tight seal between the ventilator and your face, filtering at least 95% of the airborne particles. They can include an exhalation valve to facilitate breathing when worn.and are passed from person to person through vapor (breathing), talking, coughing, sneezing, saliva and transferring to commonly touched objects.
Each model N95 mask from each manufacturer is certified by the National Institute for Occupational Safety and Health. N95 surgical respirator masks undergo secondary clearance by the Food and Drug Administration for use in surgery – better protecting practitioners from exposure to substances such as patients' blood.
In healthcare in the United States, N95 masks must also undergo a mandatory fit test before use using a protocol established by OSHA, the Occupational Safety and Health Administration. This video from manufacturer 3M shows some of the main differences between standard surgical masks and N95 masks. Homemade masks are not regulated, although some hospital websites point to preferred patterns they suggest using.
Handmade face masks: cotton and elastic
Homemade face masks canwith a sewing machine or sewn by hand. There are even techniques for not sewing, such as using a hot iron or a bandana (or other cloth) and rubber bands. Many sites offer patterns and instructions that use multiple layers of cotton, elastic bands and regular thread.
Generally, the patterns contain simple pleats with elastic straps that fit over your ears. Some are more contoured to resemble the shape of N95 masks. Still others contain bags in which you can add "filter media" that you can buy elsewhere.
Please note that there is no strong scientific evidence that the masks will conform tightly enough to the face to form a seal, or that the filter material inside will work effectively. For example, standard surgical masks are known to leave gaps. Therefore, the CDC emphasizes other precautions, such as washing your hands and distancing yourself from others, in addition to wearing a face cover in crowded areas and coronavirus hotspots when going out in public.
Which homemade masks were used first (not COVID-19)
Many sites with patterns and instructions for homemade masks were created as a fashionable way to prevent the wearer from inhaling large particles, such as car exhausts ; s, air pollution and pollen during the allergy season. They have not been taken as a way of protecting you from obtaining COVID-19. However, the CDC believes that these masks can slow the spread of the coronavirus, as other types of masks are no longer widely available.
One site, CraftPassion, contains this disclaimer:
Due to recent coronavirus attacks around the world, I have received many requests about adding non-woven filters in the face mask. Disclaimer: This face mask is not intended to replace the surgical face mask, it is an emergency plan for those who do not benefit from a surgical mask on the market. Proper use of a surgical mask is still the best way to prevent virus infection.
