These 3M masks are about as good as it gets for a disposable protective face mask.

This mask is a particulate respirator that is NIOSH approved as a Type N95 respirator. It meets CDC guidelines for TB exposure control and is designed specifically for use in a health care setting. It can be used during laser surgery, electrocautery, and other procedures using powered medical instruments to help reduce exposure to airborne particles.

With a greater than 99% BFE and fluid resistant, it has no natural rubber latex or dry natural rubber as components.

The respirator has an inner shell for comfort and the mask is hypoallergenic to reduce the chance of allergic reaction.
