Cloth Face Masks with built-in filter pocket. Kids masks are random tie-dye and may not be the exact tie-dye pattern shown here. For extra protection, don't forget to grab some 5 layer charcoal filters to put in your mask. Each filter lasts 3 to 5 days. Make sure you place the filter so that the side with the PM 2.5 is facing your face.
"For an additional layer of prevention and security, insert the five-layer PM2.5 Filter into a reusable face mask to keep away from a range of airborne particles. Using a filter in your mask is perfect for those who are still working around others, the trips to the grocery store, and any other necessary errands."
