3M N95 filter pads refer to the replaceable filter components used in 3M's line of N95 respirators. N95 respirators are personal protective equipment designed to provide a high level of respiratory protection against airborne particles, including viruses and bacteria. The "N95" designation indicates that these respirators are capable of filtering out at least 95% of airborne particles.
The filter pads in 3M N95 respirators play a critical role in trapping and filtering out particles from the air before it reaches the wearer's respiratory system. These filter pads are designed to be replaceable, as they can become clogged over time with particles that they've filtered out. Regular replacement of the filter pads helps ensure that the respirator maintains its effectiveness.
