3M™ E-A-R™ Classic™ Earplugs have set the industry standard for noise reduction as the world's first foam earplugs. These earplugs are made of a proprietary soft energy-absorbing slow-recovery foam that's designed to conform to the shape of the ear canal to help provide hearing protection. This earplug's moisture resistant foam is initially firm to make fitting the earplug easier, softening once its in the ear to comfortably expand and conform to the shape of each ear canal. The slow recovery feature helps with earplug insertion by giving the user time to get the compressed foam cylinder (rolled down earplug) into the ear before the foam fully expands. Per-pair packaging options include a pillow pack that can be used to store earplugs between uses or a standard polybag; dispenser bottles for One Touch Pro dispenser are also available. Comes with or without cord to suit user preference. This product is EARfit testable to help validate the level of protection the individual user can achieve with this product. The world`s first foam earplugs and still the most widely used cylindrical earplug today. Packaged in convenient Refill Bottles to fit your One Touch dispenser. • Flame-resistant and moisture-resistant • Noise Reduction Rating (NRR)*: 29 dB CSA Class AL • Test compatible with 3M E-A-Rfit Validation System *The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. 3M is Leading the Advancement of Hearing Conservation.
