The respirator masks that are designated with the filter class of N95 means that the respirator filter will block at least 95% of small particles. The N refers to its pr…operties related to oil resistance of the mask: N = Not Oil Resistant, R = Oil Resistant, P = Oil Proof
Not if you are wearing it to protect you from viruses or other sub-microscopic pathogens or pollution/fumes. These N95 masks are more like respirators than a cloth or pape…r surgical mask. None of these should be reused when used for medical purposes, they should be thrown away after each use since they may harbor some of the filtered particles on the outside that could contaminate people or environments. They can not be washed for reuse, either, this will potentially deform or disintegrate the mask rendering it ineffective. N95 masks must also be medically fit to your face or they will not be effective. They are not recommended for children or those with beards or mustaches because that can allow gaps for particles to enter around the mask. See more in the related questions section.
N95 respirators are typically manufactured from a polypropylene (PP) material which does not have any degradation in performance over time if stored in normal conditions…. They do not expire. After a mask is removed from the box in which it is sold, it generally should be used within a day in order to avoid / minimize contamination from airborne particles which might settle on the inside surface of the exposed mask.

The N95 is going to filter 95% of the particles in the air, hence the name N95. It will protect the respiratory system against lead, however, the largest worry with lead is to…pical exposure, or exposure from skin contact. While the mask will protect your respiratory system from the lead particles, if you are grinding or sawing, bare skin will still be exposed. If you are extremely worried about protecting the respiratory system, then the P100 is the next best thing to an SCBA. The downside to the P100 is the upkeep, the training, and the record keeping required by OSHA.
