3M 8233 N100 Particulate Respirator

Many refer to the 8233 as the 3M lead mask, 3M lead dust respirator or 3M lead dust mask.

The 3M 8233 N100 particulate respirator is for those who want NIOSH's highest rated filter efficiency in a maintenance free mask. The N100 rating indicates that this mask is 99.97% effective against particles .3 microns and larger. Each mask is individually wrapped to prevent contamination.

Approved for lead abatement, metal fumes produced from welding, certain radioactive particulate material and non-oil containing mists. Recent recommendations include Avian Flu and Swine Flu from the CDC, though N95 masks are also recommended, and may be just as good and a whole lot cheaper.

Cool-Flow exhalation valve helps keep the mask cool and dry. Soft inner faceseal conforms to your face, offering better than average seal for a disposable mask. Not approved for asbestos.

Individually wrapped and sold by the each.

This mask has been a popular choice for protection against Avian flu, Bird flu, Tuberculosis / TB, SARS, and Swine flu.

The 3M 8233 compares to the now discontinued 9970. That mask was rated as a HEPA filtered mask. Since then, NIOSH has changed this designation to either N100 (no oil) or P100 (resists oil). Another cross would be to the 3M 8293, which carries the P100 rating. We don't stock that mask, but it can be ordered by request.
