3M 7100001858 Foam Earplug Refill Large Yellow 33 Db Nrr

Product Description

The 3M 7100001858 is an uncorded foam earplug refill designed for use with the 3M One Touch dispenser model 391-1000. These earplugs feature a soft, low-pressure foam construction that reduces listener fatigue during extended wear in high-noise industrial and trade environments. The large size is intended for workers with larger ear canals, and the Noise Reduction Rating (NRR) of 33 dB makes this refill appropriate for environments with significant ambient noise. Each case is packaged in refill bottles sized to drop directly into the compatible dispenser without repackaging or handling individual pairs.

These earplug refills are suited for use on commercial and industrial job sites including mechanical rooms, construction sites, manufacturing floors, and other environments where hearing protection programs are in place. The refill format supports high-traffic dispensing stations, making them practical for shops, facilities, and crews that go through hearing protection at volume. Large-size earplugs address fit compliance for workers who find standard sizes uncomfortable or insufficiently sealing.

Key Features

• 33 dB NRR foam earplugs rated CSA Class AL for hearing protection compliance

• Soft, low-pressure foam construction reduces discomfort during extended wear

Compatibility

Packaged as refill bottles specifically designed to fit the 3M One Touch dispenser 391-1000.

Installation Notes

Hearing protection is typically administered under a site safety program overseen by a competent person or safety officer. Workers should be trained on proper earplug insertion technique, as improper fit reduces effective attenuation below the rated NRR. Note that 3M recommends reducing the NRR by 50 percent when estimating real-world noise reduction during typical use. Refill bottles should be loaded into the dispenser according to the dispenser manufacturer instructions.
