Product Details
The 3M™ E-A-R Classic™ earplugs, uncorded, are packaged in a poly bag containing 200 pairs and are identified by the model number 312-1201. These disposable earplugs are constructed from slow-recovery foam, making them uniquely moisture-resistant and setting the standard in hearing protection as the world's first foam earplugs. Known for their economical and reliable performance, they continue to be one of the most widely used foam earplugs available. The slow recovery, low-pressure foam material conforms to the shape of the ear canal, creating a comfortable and snug noise barrier. Key features include a noise reduction rating (NRR) of 29 dB, flame-resistant and moisture-resistant properties, and compatibility with the CSA Class AL test, as well as the 3M™ E-A-Rfit™ validation system.
