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

Before you actually make any masks at home,

Nishi Viswanathan: Basic precautions like handwashing

with anything that indicates that it can kill viruses.

Something practical would be to wear a mask yourself

Narrator: Viswanathan also recommends washing your fabric

While there are several materials being recommended

Raina MacIntyre: You want a material that repels water,

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

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.

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.

This third design requires a sewing machine

and elastic pieces or string or hair ties,

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

Next you add 6-inch elastic pieces or something similar

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

some experts recommend taking things a step further

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

And if you can get hold of disposable filters,

Narrator: Sudeb Dalai, a Stanford physician specializing

in infectious diseases, recommends masks with filters

for people who anticipate prolonged exposure

are taking care of someone with COVID-19,

using polypropylene material or HEPA vacuum bag filters

because they're breathable but still effective

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

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

the air will just follow the path of least resistance.

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

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

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.
