Eco Chic Mask Filter 5pk
5 x PM2.5 filters per pack. Made of activated carbon and non-woven melt-blown filter cloth, this product has a five-layer filter system to protect you from particles in the air. These filters fit neatly into Eco Chic's Reusable Face Covers (and others) to filter approximately 90% of airborne particulates of over 2.5 micrometers. Wearing a face mask prevents the spread of droplets into the air when coughing or sneezing.
