Wearing a face mask is one of the best preventative measures against COVID-19 at the moment, and you can upgrade your PPE today with the multi-layer Copper.Iron mask from Grid, which has copper woven right into the fabric. These masks use five filter layers for protection, and since they're machine washable, they can last a few weeks or months before needing to be replaced. And right now, you can find mask packs for up to 60 percent off, with single masks starting at $20.

Copper has always been thought to have major health advantages, and it's even been recognized as the first antimicrobial metallic surface approved by the U.S. Environmental Protection Agency. The company states that the copper woven into its nylon mask is used to help cut down on unpleasant odors that may develop over prolonged use.
