Reliable Hearing Protection

3M E-A-R Classic uncorded earplugs deliver a dependable choice for hearing conservation in noisy workplaces. Slow-recovery foam conforms to the ear canal to create a comfortable, snug noise barrier. The Noise Reduction Rating is 29 decibels and they meet CSA Class AL requirements.

Disposable and Moisture Resistant

Each pair is flame-resistant and uniquely moisture-resistant for durability in demanding conditions. A poly bag keeps the PVC earplugs clean before use. The cordless design allows quick insertion and removal without tangling during shift changes.

Upgrade from Basic Plugs

These replace loose-fitting or non-rated plugs that let harmful noise through. The jump is worth it when a validated 29 NRR and moisture resistance are required for compliance and all-day comfort. Test compatibility with the 3M E-A-Rfit Validation System supports fit verification.
