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.\u003c\/p\u003e\n\u003cp\u003eThese 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e33 dB NRR foam earplugs rated CSA Class AL for hearing protection compliance\u003c\/li\u003e\n  \u003cli\u003eLarge size designed to fit workers with larger ear canals\u003c\/li\u003e\n  \u003cli\u003eSoft, low-pressure foam construction reduces discomfort during extended wear\u003c\/li\u003e\n  \u003cli\u003eRefill bottle format fits directly into the 3M One Touch dispenser 391-1000\u003c\/li\u003e\n  \u003cli\u003eUncorded design for unrestricted movement in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePackaged as refill bottles specifically designed to fit the 3M One Touch dispenser 391-1000.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHearing 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.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoise Reduction Rating (NRR)\u003c\/strong\u003e: 33 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCSA Rating\u003c\/strong\u003e: Class AL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: Large\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Uncorded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Dispenser\u003c\/strong\u003e: 3M One Touch 391-1000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 6.89 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 17.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 15.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 10080529910056\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100001858\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344228024626,"sku":"7100001858","price":298.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536172.jpg?v=1782032260","url":"https:\/\/voomisupply.com\/products\/3m-7100001858-foam-earplug-refill-large-yellow-33-db-nrr","provider":"Voomi Supply","version":"1.0","type":"link"}
