Coronavirus: effectiveness of types of masks and manufacture of a homemade respiratory mask

[gegyx]

Homemade mask, not approved, Banzaï, for lack of nothing ...

Paper towel, handkerchief, metal tie for freezer bag, adhesive tape, staple or sewing
In addition there is the visor.

It can be a "hands-on" occupation for children.

/ for my part I think that a headband, neck warmer or brief to hold, and cotton wool or paper towel inside it is also valid.

An idea: can we perhaps improve the filtration of a fabric by folding it in a tight accordion, like hepa filters?

I saw the cloth one made by a nurse.

the filter, a rectangle cut from the "micro-polar" wipe added inside the fabric envelope, the whole is washable by separating them.

For me, at random I would boil in a pan at 100 ° for 10mn?

At my taff I made a hygiaphone between our customers and us ... With stretched pallet film, the vision is good as it vibrates we hear what the people tell us good to avoid drafts ... It stretches and distorts the film ... it's been three weeks that it is in place ... It will be renewed ...

I like this model for those who have a 3D printer.

Some improvements are possible to ensure with adhesive TESA, a relative seal of contact between the mask and the face ...
The mask and reusable after disinfection is not bad either.

I love the coffee filter method! This is the eco corner corner mask!

By cons must think of doubling or tripling!

And put a filter element between the layers!

Have you thought about using a vacuum bag as a raw material to make a mask?
