Mask Information

 From Family Voices Washington D.C. Update 2.2.2021

• Types of masks. With rising concerns about new variants of the SARS-CoV2, some experts are recommending that people wear two masks (Washington Post, 01/27/21) or use high-filtration masks Washington Post, 01/20/21). See Understanding Mask Types (American Dental Association, 10/02/20); and this article (from CBS News, 01/27/21) explains the differences among mask types. See also FAQ: Single or double? The latest advice on masks and COVID (Washington Post, 01/26/21).
• Counterfeit masks. If seeking to buy an N95 mask, it is important to beware. Many mask manufacturers are falsely labeling their products as NIOSH-approved N95 masks (photos of many counterfeit masks). NIOSH is the National Institute for Occupational Safety and Health.
