PM2.5 filter features 2 layers of Meltblown filter and 1 layer of carbon activated fabric, designed to effectively block airborne contaminants. Take the filter out of the mask before washing. The filter should be replaced every 1-2 weeks of occasional wear or when it gets harder to take a breath. Filters available in 2 sizes to fit our adult and kid masks.
*Only for our masks with filter pockets. Pleated masks do not have filter pockets. *
