N95tüüpi

N95tüüpi refers to respirators that meet the N95 standard established by the National Institute for Occupational Safety and Health (NIOSH). These respirators are designed to filter out at least 95% of airborne particles, including very fine ones that can be harmful. The "N" in N95 stands for "Not resistant to oil," meaning these masks are suitable for use in environments where oil-based aerosols are not present.

The primary function of an N95 respirator is to protect the wearer from inhaling hazardous airborne substances. This includes dust, fumes, mists, and biological agents such as viruses and bacteria. They are commonly used in occupational settings where exposure to airborne contaminants is a concern, such as construction, healthcare, and manufacturing.

To be effective, an N95 respirator must form a tight seal against the wearer's face. This is typically achieved through adjustable nose pieces and ear loops or headbands. Proper fit testing is often recommended to ensure the respirator provides adequate protection. While N95 respirators are highly effective at filtering particles, they do not supply oxygen and should not be used in atmospheres with oxygen levels below 19.5%. They also do not protect against gases or vapors.
