Disposable Earplugs
Disposable Earplugs are typically polyurethane foam or PVC that is rolled by hand and inserted into the ear canal where it expands to seal. They differ from reusable earplugs by being inexpensive, with SNR/NRR checked per model in product data, and being replaced after each use or shift. Ideal for visitors, temporary workers, and emergency programs.

About this category
Disposable foam earplug design is unique: the worker rolls the foam between fingers to reduce its diameter, then inserts it into the ear canal where it expands slowly to take the canal shape. This flexible design achieves a complete seal even in atypical canals. SNR is typically 29-37 dB (among the highest for earplugs), but real effectiveness depends on correct insertion (sufficient depth). Rolldown models are the most common. Push-in models have a solid plastic stem used to push them in without rolling and suit workers who wear gloves. Common materials: polyurethane foam (most comfortable), PVC (higher attenuation but less comfortable). They come in several colors for visual check of correct wear (blue for food-safe, yellow for general). Correct use needs rolling to the smallest diameter, pulling the ear up, inserting to sufficient depth, and waiting 30 seconds to expand. Replace daily or between shifts. Suited to factory visitors, emergency operations, and intermittent exposure. Specifications follow EN 352-2 and ANSI S3.19.
