Though the CDC recommends we wear masks, we shouldn't buy surgical masks or N95 respirator masks. Those types are desperately needed by health care workers and first responders who are in constant proximity with coronavirus patients every day, and supplies in some areas are dwindling.
You can, however, easily make your own cloth mask from old clothes or other common materials and household items. And you don't even have to sew. You can make one using a bandana and coffee filter. US Surgeon General Jerome Adams showed us how to make face masks with a T-shirt and rubber bands in this CDC video.
"Ultimately, it's about having some form of barrier with multiple layers," said CNN Chief Medical Correspondent Dr. Sanjay Gupta in a CNN video on why masks in addition to physical distancing are important.
Masks made with a combination of cotton with natural silk or chiffon may also effectively filter out aerosol particles, according to a new study published Friday in the American Chemical Society Nano journal. Our respiratory droplets form in a range of sizes, but the tiny ones, called aerosol particles, can slip through the gaps between certain cloth fibers.
You could substitute the chiffon with natural silk or flannel, or use a cotton quilt with cotton-polyester insulation, to achieve similar results, the study said.
There are also disposable cloth masks you can buy in a store or online. They're not made for surgery or hospitals, but they are effective for your needs and widely used.
