How to make your own coronavirus face mask: Online DIY tutorials detail method for vacuum cleaner bag or T-shirt to create protection that leading scientists say is effective against bug
- Homemade masks offer significantly less protection than medical N95 masks
- Some medical opinion says they can be effective and better than nothing
- Items in your home, such as a t-shirt or pillowcase, can be used to make one
The worldwide coronavirus pandemic has led to a shortage of protective face masks, leading to a deluge of online tutorials ion how to make your own using a t-shirt or pillowcase.
Homemade masks offer significantly less protection than the N95 medical masks, which are made of a thick, tightly woven material that fits over the face and can stop 95 per cent of all airborne particles.
Public Health England still does not recommend Britons wear face masks, unless in a medical setting.
But there are good reasons to think DIY masks could be effective in tackling the pandemic, as they have been widely used in Hong Kong,Mongolia and South Korea -countries that largely have the disease under control.
The World Health Organisation also currently does not recommend that people without the illness wear face masks, but it could be about to reverse its decision due to evidence from Hong Kong that they may be effective in fighting the virus.
And in a further sign that attitudes about masks are changing, LA’s mayor, Eric Garcetti, yesterday told all four million of the city’s residents that they must wear face masks at all times to slow the spread of the deadly pandemic.
MailOnline has investigated how you can make your own face mask using everyday household items such as a t-shirt, kitchen towel or vacuum bags.
How to make a face mask from a t-shirt
A YouTube tutorial by Runa Ray shows how to make a face mask without any need for sewing, using just a plain t-shirt.
First of all you need scissors, pencil and a ruler, and a t-shirt you don’t mind being used to make a face mask.
Cut out a 16″ by 4″ rectangle from the middle of the t-shirt, then fold it in half, and measure four inches on either side.
Then mark the t-shirt with an even number of tassels on each side and use scissors to cut them.
Turn the t-shirt inside out and separate the corner tassels, but tie the remaining ones in-between.
Then with the remaining t-shirt material cut some ear straps using the hem of the shirt.
Attach the straps to the remaining outer tassels and you have yourself a face mask, with no sewing involved, and using an old t-shirt.
A slightly more complicated method has been perfected by researchers from the University of Pittsburgh also managed to design a face mask that could be used if ‘commercial masks’ are not available during a virus outbreak.

They used a regular cotton t-shirt, which was boiled for 10 minutes and then air-dried to sterilise the material, but also to shrink it.
The researchers used a marker and ruler to measure out what they wanted to cut and then formed the mask using an outer layer and then eight inner layers covering the nose and mouth.
The mask does not require any sewing, and instead involves it being tied multiple time around the face.

Even UK politicians have got in on the act, with Gillian Martin, who is MSP for Aberdeenshire East, describing how she made a face mask from vacuum cleaner bags and elastic.
She told the Daily Record: ‘I live in a small village and have been here for over 20 years. I don’t want to worry or offend people when I go out.
‘I started researching what other countries have been doing and came across a chart with the best materials to use to make a mask out of just about anything.’
‘Just below medical material was a hoover bag. I have loads of them lying around and found Hepa-Flow bag that just goes on your Henry hoover’.
The chart the MSP is referring to from a University of Cambridge study which shows the materials that work the best against virus sized particles.
The top three are a surgical mask, vacuum cleaner bag and tea towel.
She added: ‘I cut it up the bag and secured it with elastic. I live with my family of three who have all been self-isolating so I made one for each of us’.

‘I made it because I’m nervous of people coming up to me when I’m out walking the dog. I don’t want to have to run away from them.’
Another popular YouTube method shows how to fold up a scarf, using hair ties at either end, to make a simple and easy no-sew mask. The same method can be used with a handkerchief and doesn’t involve any sewing.
How to make a face mask from kitchen towel
For this you need two layers of kitchen towel and one of tissue.
You cut it in half, and then use masking tape on each end to ensure the mask is stiff.
Then you punch holes through either end of the mask and thread elastic bands through the holes.
Some Japanese women have even been posting instructions about how to make a face mask from a bra.
The method is simple and involves cutting off one cup with scissors and then sewing the bra straps on, so they can be attached to your face.
Do masks have to be complex to be effective?
The idea that masks do not have to be complex to be effective does have some support from recently published studies.
A University of Oxford study published this week concluded that surgical masks are just as effective at preventing respiratory infections as N95 masks for doctors, nurses and other health care workers.
It’s too early for there to be reliable data on how well they prevent infection with COVID-19, but the study found the thinner, cheaper masks do work in flu outbreaks.

The difference between surgical or face masks and N95 masks lies in the size of particles that can – and more importantly, can’t – get though the materials.
N95 respirators are made of thick, tightly woven and molded material that fits tightly over the face and can stop 95 percent of all airborne particles, while surgical masks are thinner, fit more loosely, and more porous.
This makes surgical masks much more comfortable to breathe and work in, but less effective at stopping small particles from entering your mouth and nose.
Droplets of saliva and mucous from coughs and sneezes are very small, and viral particles themselves are particularly tiny – in fact, they’re about 20-times smaller than bacteria.
Experts universally agree that there’s simply no replacement for thorough, frequent hand-washing for preventing disease transmission.
