Adult and Child Sized 5-layer Carbon Technology Protective Mask Filters
The disposable PM 2.5 mask filters are made of five layers of carbon filter tech for more thorough protection against pollutants, allergens, and particulates. Each filter has an activated carbon fiber layer between two melt blown cotton layers and is encased by a layer of non-woven fabric on each outer side, offering the air filtration to allow you breathe easier when outside of home. They fit perfectly within the built-in pocket of our adult sized protective masks. Filters should be safely disposed of after each use.
