made a mask from a bandana and a vacuum cleaner bag

you can make around 8 from a med sized bag

just a few videos i downloaded and saved today

imagine a world w/o the internet

good luck

Hopefully not fiberglass

Simple Respiratory Mask

Quality commercial masks are not always accessible, but anecdotal evidence has showed that handmade masks of cotton gauze were protective in military barracks and in healthcare workers during the Manchurian epidemic (6,7). A simple, locally made, washable mask may be a solution if commercial masks are not available. We describe the test results of 1 handmade, reusable, cotton mask.

Thumbnail of Prototype mask. A) Side view, B) Face side. This mask consisted of 1 outer layer (≈37 cm × 72 cm) rolled and cut as in panel B with 8 inner layers (<18 cm2) placed inside (against the face). The nose slit was first placed over the bridge of the nose, and the roll was tied below the back of the neck. The area around the nose was adjusted to eliminate any leakage. If the seal was not tight, it was adjusted by adding extra material under the roll between the cheek and nose or by pus

For material, we choose heavyweight T-shirts similar to the 2-ply battle dress uniform T-shirts used for protective masks against ricin and saxitoxin in mouse experiments (8). Designs and T-shirts were initially screened with a short version of a qualitative Bitrex fit test (9) (Allegro Industries, Garden Grove, CA, USA). The best were tested by using a standard quantitative fit test, the Portacount Plus Respirator Fit Tester with N95-Companion (TSI, Shoreview, MN, USA) (10). Poor results from the initial quantitative fit testing on early prototypes resulted in the addition of 4 layers of material to the simplest mask design. This mask is referred to as the prototype mask (Figure).

A scissor, marker, and ruler were used to cut out 1 outer layer (&#8776;37 × 72 cm) and 8 inner layers (<18 cm2). The mask was assembled and fitted as shown in the Figure.

A fit factor is the number generated during quantitative fit testing by simulating workplace activities (a series of exercises, each 1 minute in duration). The Portacount Plus Respirator Fit Tester with N95-Companion used for the test is an ambient aerosol instrument that measures aerosol concentration outside and inside the prototype mask. The challenge agent used is the ambient microscopic dust and other aerosols that are present in the air.

Thanks for the bread recipe

Here the CDC planned the whole thing out for you

Lol making

good idea. Thanks OP.

Hmmm... interesting...

May be just as useful as chopping a bra in half and using the cups with a nose pin, lol...

Well... you never know!

Kotex with wings ...stick to face....

You can also use woman's panties, preferably used for a few days so there is some dampness. If they are from a small woman you can just use the leg holes to attach them to your ears. If you have a large woman like me then you can wear a motorcycle helmet with the visor raised, pull the big girl panties down over the helmet, the elastic will grip your neck.

I get strange looks when I ride down the road but they won't be laughing when they can't breathe soon. I will be fine.

This gets five stars!


I will get a new IP and give you five more if you make a bikini top out of another vacuum bag.

Make sure you shave beard first...
