New 5 pack 3M dust mask in package
This mask is for typical house dust. It has a higher filtration efficiency than other unapproved masks as per independent laboratory testing with particle sizes of 0.3 to 10 microns. While not a government approved respirator, the patented material in the 3M home dust mask filters more than 90% of particles. Wear the dust mask while house-cleaning, sweeping the garage, gardening, raking leaves, or cutting the lawn. This mask can also be used as an air-warming mask by those who work or exercise in cold air and are irritated by its effects. 2 elastic head straps hold the mask firmly in place. A flexible, adjustable noseclip reduces pressure points and provides added comfort for the user. The patent-pending, multi-layer construction improves durability and helps reduce collapsing.
