Homemade face masks: how and from which fabric it is better to make them

Why is it best to make a mask if you don’t have a ready-made one that you can usually buy at a pharmacy? If you want to make a mask yourself at home, the first question will be: why? T-shirts? They all have different thicknesses. Why not try a kitchen towel or handkerchief or even a paper towel. Edition with the BBC understood the properties of all materials.

Smart Air is a social enterprise that tests the protection level of different masks against pollution. They pump air into the tube and test what percentage of coronavirus-sized particles can pass through different types of materials.

Researchers have found that coffee filters, kitchen towels, and nylon block particles better, but it’s impossible to breathe through them.

“We have found that the best materials for masks are paper napkins, lightweight canvas and denim. Old jeans and bedsheets work very well,” says Smart Air chief Paddy Robertson.

In many countries of the world, the production of protective masks from improvised materials has gained momentum.

The monks in Thailand use fabric from their robes, and in the USA, the general surgeon published a video instruction on how to make the mask yourself. But some of the materials on offer are too porous.

“We tested 3 different lightweight scarves, and they all did a very poor job of filtering out fine particles,” says Robertson.

“To determine if a material is suitable for a mask, hold it up to light and see how it transmits it. This will give you a general idea of ​​whether the material is capable of filtering particles. More light means the material will let more particles through, the one that lets in less light is effective,” adds Robertson.

However, Robertson says that their study is not an absolute fact.

“The best materials we found filtered between 30% and 40%, which is better than nothing at all, but clearly doesn’t solve the problem,” says Robertson.

In addition, the pace of production of surgical masks is increasing worldwide, so soon everyone who needs them will receive them, but even such masks may not guarantee complete protection.
