Disposable ear plugs for high-noise environments

These uncorded foam ear plugs are designed for workers who need reliable hearing protection in loud industrial or construction settings. The regular size and tapered shape suit most adult ear canals. Each box contains 200 pairs for extended team supply. They are tested compatible with the 3M E-A-Rfit Validation System for fit verification.

Soft polyurethane foam with 33 dB NRR

The slow-recovery foam expands gently inside the ear canal to create a consistent seal without excessive pressure. This design delivers a Noise Reduction Rating of 33 decibels and meets CSA Class AL requirements. The material resists moisture and maintains its shape during long shifts. No power or electronic components are involved.

Poly bag keeps plugs clean before use

Each pair is stored loose in a protective poly bag that prevents contamination from dust or debris before insertion. The uncorded format eliminates tangling and allows quick disposal after a single use. No additional accessories, dispensers or software are included in the package. The box simply replenishes personal protective equipment stock.

Questions about this item

How do I insert the self-adjusting foam earplugs so they expand properly in my ear canal?

Roll the plug tightly between clean fingers, pull the outer ear up and back, insert deeply, then hold until the slow-recovery foam fully expands to seal the canal.

When should I replace the uncorded plugs from the 200-count box?

Discard each pair after a single shift or whenever the foam becomes soiled, damaged, or no longer springs back to its original shape.

What protection limit appears first during continuous high-noise exposure?

The rated Noise Reduction Rating of 33 decibels defines the maximum attenuation these plugs provide under sustained use.
