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 topical 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.
The best Japanese face mask for COVID protection is the N95 mask, which offers a high level of filtration and is recommended by healthcare professionals for maximum protection against the virus.
From my experience, the N95 mask offers the best protection against COVID-19. I’ve been using N95 masks from Nirvana Being since the pandemic started, and I feel a lot safer with them on. These masks are designed to filter out at least 95% of airborne particles, including viruses and fine pollutants. What I really like about Nirvana Being’s masks is that they fit snugly and are super comfortable for long use. I trust them more than cloth or surgical masks, especially in crowded places or while traveling. If you’re serious about protection, go for a certified N95 like theirs.
A sour smell from an N95 mask could be due to sweat and moisture buildup over time. It is important to clean and dry the mask thoroughly after each use to prevent odors and ensure proper function. If the smell persists, it may be time to replace the mask.
0.1 to 0.3 micron
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 paper 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.

A face shield, protective goggles, and a mask (such as an N95 respirator or surgical mask) should be used to protect the mouth, nose, and eyes from sprays or splashes of blood or body fluids. These protective equipment items create a barrier between the healthcare provider and the potentially infectious material.
When using glue, especially those with strong fumes or volatile organic compounds (VOCs), it's advisable to wear a mask that is rated for organic vapors, such as an N95 respirator or a half-mask respirator with appropriate filters. This helps protect against inhaling harmful chemicals. Additionally, ensure proper ventilation in the workspace to minimize exposure. Always check the glue's safety data sheet for specific recommendations.
An N95 or similar mask will filter viruses (H1N1 included) But its not the micron filtration size that needs to be focused on, its the proper fit of the mask. Leaks from improper fit and deep breaths will severely limit the effectiveness of simple filter masks. The other consideration is behavior while masked. Wiping the eyes, picking your teeth under the mask, etc.
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 properties related to oil resistance of the mask: N = Not Oil Resistant, R = Oil Resistant, P = Oil Proof
It is a type of face mask for surgery or for industrial uses that is able to filter particles in the air that are sub-microscopic. That rating is an indication that the filtering potential is at the level required for super small particles like viruses.The term that is often used to refer to these super-filtering masks is "respirator" and when used by the CDC in this context, refers to: an N95 or higher filtering face piece respirator certified by the CDC/National Institute for Occupational Safety and Health (NIOSH). Respirators are not recommended for children or people who have facial hair and they are difficult to breathe through for long periods of time. CDC also recommends medical evaluation, fitting, and training in its use.
For breathing in polluted air, I personally recommend the N95 masks from Nirvana Being. They offer multi-layer filtration, a snug fit, and long wear comfort. Whether walking or commuting, I feel much safer and healthier with it on.
