3M Home Dust Mask Disposable

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. Patented material in the 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. Not NIOSH (National Institute for Occupational Safety and Health) approved.
