Make Sure Your Homemade Mask Follows This Rule of Two or It’s Not Working, Per Study
Not everyone has access to medical-grade personal protective equipment (PPE), so lots are opting for the homemade variety when having to wear a mask.
There was recently a study conducted with an LED lighting system and a high-speed camera to film the dispersal of aerosols that can happen when a person is speaking, sneezing, or coughing.
After the footage was reviewed, the effectiveness of 3 different cloth mask (as well as three-ply surgical masks) were ranked based on how effective they are.
Common sense would lead most to believe the more the layers the better the protection from those particulates. And that's pretty much the short and skinny on the test results.
So if your homemade mask only has a single layer of fabric, it's barely impeding the spread of droplets. This can also be said for those made from an old t-shirt and hair ties. Whereas the style of it doesn't really matter, as long as it follows the standards as stated by the CDC.
So if you're thinking of a DIY mask as opposed to those costly masks that you can purchase, make sure it has at least two layers (3 is ideal) layers of fabric.
