Earplugs THOR One size yellow PU SNR 37 dB 200 pairs

THOR One size yellow PU earplugs are disposable hearing protectors made from polyurethane foam with a noise reduction rated SNR 37 dB. Supplied as a pack of 200 pairs, these earplugs are designed for general-purpose noise attenuation in environments with elevated sound levels. The bright yellow colour improves visibility for inventory and compliance checks while the soft PU foam provides a comfortable fit for short-term use.

Advantages

These earplugs combine a high attenuation level with a soft, slow‑rebound PU foam that adapts to the ear canal for a secure seal. The one‑size design simplifies fit selection, and the bright yellow finish makes the product easy to locate and count. Supplied in a bulk pack of 200 pairs, they are suitable for workplaces and events where frequent replacement or shared provisioning is required.

How to use

Compress the earplug between thumb and forefinger to a narrow cylinder, gently insert into the ear canal and hold in place for a few seconds while the foam expands to form a seal. Ensure the earplug is fully inserted for optimal attenuation and check fit by confirming a noticeable reduction in ambient noise. Replace earplugs after soiling, deformation or when they no longer expand properly. These earplugs are intended for single‑use only and should be discarded after use.

Usage recommendations

Store earplugs in a clean, dry place away from direct sunlight and extreme temperatures. For environments with chemical exposure, wet conditions or where hygiene requirements are strict, consider dedicated or reusable hearing protection with appropriate maintenance. Follow workplace hearing protection policies and perform regular fit checks to ensure effective noise reduction.
