  • The CDC recommends wearing a mask

  • anytime you go out now,

  • but masks are in short supply in a lot of places,

  • and there's a push to preserve medical masks

  • for medical workers who are putting themselves at risk.

  • So we talked to experts about the best way

  • to make and wear a mask at home.

  • Before you actually make any masks at home,

  • you should take some precautions.

  • Nishi Viswanathan: Basic precautions like handwashing

  • of course, like, before beginning work,

  • and disinfecting the surface

  • with anything that indicates that it can kill viruses.

  • Something practical would be to wear a mask yourself

  • if you're making masks.

  • Narrator: Viswanathan also recommends washing your fabric

  • in hot water before making masks.

  • This way the fabric will be clean

  • and also won't change in size again.

  • While there are several materials being recommended

  • for masks by experts, overall...

  • Raina MacIntyre: You want a material that repels water,

  • not one that absorbs water.

  • So, a normal surgical mask, for example, is water resistant.

  • So you want something that repels water

  • but that's still breathable.

  • Narrator: There are a lot of different

  • mask designs available, but we're gonna show you

  • how to make the three recommended by the CDC.

  • You can make this first one using a T-shirt.

  • Again, a cotton-polyester blend would be best.

  • You cut off the bottom of the T-shirt,

  • cut out tie strings, and then tie it around your head.

  • This next design can also be made with a bandana

  • or any square cotton cloth that's 20 inches by 20 inches,

  • along with two hair ties or rubber bands.

  • Add the hair ties to both sides,

  • tuck in the bandana ends,

  • and then you're all set.

  • This third design requires a sewing machine

  • to make a relatively simple mask

  • from some kind of cotton fabric

  • and elastic pieces or string or hair ties,

  • whatever you have on hand.

  • You cut two 10-by-6-inch rectangles of cotton fabric

  • and stack them to sew them together.

  • You fold and hem the long sides,

  • then the same on the short sides.

  • Next you add 6-inch elastic pieces or something similar

  • through the hems and tie the ends.

  • Tuck the knots in the hem and stitch the elastic into place.

  • If you have access to a sewing machine,

  • some experts recommend taking things a step further

  • by following a design with more layers

  • as well as a pocket for a disposable filter.

  • MacIntyre: So, having three layers is best.

  • In some of the designs, you can make a pouch in the front

  • where you put a disposable filtering.

  • And if you can get hold of disposable filters,

  • then that's a good option as well,

  • because those filters are designed

  • to be like a respirator in essence.

  • Narrator: Sudeb Dalai, a Stanford physician specializing

  • in infectious diseases, recommends masks with filters

  • for people who anticipate prolonged exposure

  • or close contact with other people,

  • are taking care of someone with COVID-19,

  • or have an underlying condition.

  • To make a filter, Dalai recommends

  • using polypropylene material or HEPA vacuum bag filters

  • because they're breathable but still effective

  • at filtering tiny particles.

  • Dalai also says to make sure any filters are placed

  • between two layers of fabric to protect your skin

  • as well as to prevent breathing in the filter material.

  • Regardless of the design, you're gonna wanna make sure

  • that your mask fits properly.

  • MacIntyre: So, it should fit around

  • the contour of your face.

  • Whether you use the elastic or any other material

  • to help mold it around the edges, that will help,

  • because otherwise you get a lot of air leakage

  • through the sides, and when you breathe,

  • the air will just follow the path of least resistance.

  • So if the sides are flapping open,

  • it'll just go in through the sides.

  • Narrator: It's also important that your mask fits well

  • so that you aren't touching it

  • again and again to readjust it.

  • Viswanathan: It has to extend to

  • the top of the bridge of the nose

  • and then below the chin.

  • So it has to provide adequate coverage

  • and has to sit comfortably on the nose

  • without, like, sliding off.

  • MacIntyre: The process of putting on and taking off the mask

  • is also really important

  • because the mask can become contaminated.

  • So if you're out and about and you want to store your mask,

  • it's better to use something like a Ziploc bag.

  • Just keep it in your pocket

  • rather than just putting it in your pocket

  • because the mask itself could be contaminated.

  • Narrator: So, you should be washing your hands

  • before and after touching your mask

  • as well as cleaning it after every wear.

  • Viswanathan: One thing to remember when wearing masks

  • is that they are not substitutes for social distancing.

  • So definitely follow the social-distancing guidelines

  • that you have been following all along.
