On April 3, U.S. health officials recommended a handicraft project to U.S. citizens: make a fabric mask and wear it when you go out in public.

Covering the mouth and nose is another way people, in addition to social distancing and washing their hands, can slow down the spread of the novel coronavirus, according to the disease control and prevention centers. Medical masks are rare and should be reserved for frontline healthcare workers who are repeatedly exposed to large amounts of the virus.

However, a DIY face covering offers the wearer a bit of protection while preventing him from unwittingly spreading the virus to others. This is useful if, according to the CDC, up to a quarter of people with Covid-19 may experience no symptoms.

Count me in. What material should I use?

The corona virus is extremely small – too small to be trapped by most substances through which air can still flow.

However, the virus appears to be most transmissible when it adheres to much larger droplets of water or mucus that come out of the mouth and nose when coughing, sneezing, or speaking, and a homemade mask can block these droplets.

Since the mask must be made from something you already have in the house, cotton seems to be a good choice. The CDC recommends two layers of tightly woven 100 percent cotton, e.g. B. quilter material or sheets with a high thread count.

A group of scientists and doctors at Wake Forest University tested various masks made by community volunteers and found two of the better options: a double layer of cotton with at least 180 threads and a double layer of normal cotton with a layer of Flannel in between.

Speaking of layers, don’t just stack them up. You need to find a balance between breathability and filtration.

Make sure you can breathe comfortably through your nose while wearing the mask – sticky nasal hair can also catch some particles before they get deeper into your airways. If the mask is not porous enough, breathe through the sides rather than through.

For example, vacuum bags can be difficult to breathe unless you are an actual vacuum cleaner. (And be careful – some may contain fiber and other fibers that you don’t want to breathe in.)

A group of researchers from the University of Cambridge compared the filtration and breathability of different types of homemade mask materials. They came to the conclusion that masks made from pillow cases or cotton T-shirts found the best balance.

What pattern should I use and what if I can’t sew?

There is no design that represents the consensus gold standard for a DIY mask. Patterns are floating around everywhere, and studies have shown that every face covering is better than nothing.

Here’s one that Grace Jun, a professor of fashion at the Parsons School of Design, created for The Post in consultation with health professionals in New York.

The CDC website contains some patterns, including one with a coffee filter and one without sewing – just scissors and a willingness to sacrifice a t-shirt. General surgeon Jerome Adams released a video in which he made a mask out of fabric and rubber bands.

Whichever style you choose, make sure the mask fits well and covers your nose and chin.

Once you’ve attached your new mask to your face, leave it outside while you’re outside and don’t touch the front – as you wouldn’t touch your face.

I carried my creation in the store. Can I take it off now?

Yes, and you should. When you’re back in public after wearing your fancy new mask, remove it without touching the front and without touching your eyes, nose, or mouth.

You want to clean it before you wear it again. You do not have to wash your mask differently than other laundry, as the soap in the detergent should destroy all viruses.

Why can’t I just buy a surgical mask or ventilator?

The CDC demands that these masks be kept for healthcare workers who are exposed to a much higher dose of the virus than a person would encounter on a short trip to the grocery store.

These two masks, worn by healthcare workers, offer very different types of protection.

Designed to reduce the wearer’s exposure to very small particles and droplets and to protect the patient from the wearer’s respiratory emissions.

The nose clip and mask must be checked for fit to ensure that there are no gaps.

The higher the exposure, the more likely a person will get sick – and the extent of the exposure is also likely to play a major role in the severity of the disease.

“I think the dose is really important,” said Vineet Menachery, a virologist at the University of Texas Medical Department at Galveston, who specializes in studying coronaviruses. “The higher the dose you get, the more likely you will get sick.”
