President Donald Trump said the Centers for Disease Control and Prevention now recommends that people wear “non-medical cloth” face coverings when entering public spaces.
However, masks are an extra precaution, not a replacement for what we should already be practicing amid the coronavirus pandemic: regular hand washing, not touching your face, and social distancing of at least 6 feet.
If you find yourself trying to make a homemade mask, be sure to follow some of these important guidelines:
- Good coverage is important.
- Try to find a nonwoven material.
- A mask should be snug and reach above the bridge of the nose and below the chin.
In this video tutorial above, we used blue shop towels because the nonwoven material is strong and can filter out virus droplets.
In a Washington Post interview with Peter Tsai, the scientist who invented the electrostatic charging technology that N95 masks use, Tsai recommended shop towels as a strong alternative to fabric that would filter out droplets better than cloth.
The shop towels can even be used as a filtering layer if you decide to sew a cloth mask. This material is not perfect, but it is inexpensive and can be found at most auto supply or big box stores. The other required materials are common household items: rubber bands, paperclips, a stapler and tape.
These DIY masks will stop large droplets from getting in or getting out if worn properly.
