FACE MASKS, EXTRA FACE MASK FILTER HOUSINGS, AND FACE SHIELD HOLDERS ARE MADE IN THE USA FROM A FOOD-SAFE PLASTIC.
USE FOR WORKING IN YOUR GARAGE, YARD, OR ANYWHERE TO COMBAT DUST AND LIGHT DEBRIS.
HAND WASH ONLY IN WARM, NOT HOT, WATER. NOT DISHWASHER OR OVEN SAFE.
We have developed designs for masks with round filters sized between 48mm (1.9 inch) and 60mm (2.4 inch). We have selected this size as compatible with commonly available cotton rounds, though users may select other filtration materials at least 1.5 mm (0.06 inch) thick, allowing the user with access to extend the usefulness of a single mask.
