Moldex Pura-Fit earplugs give you NRR 33 protection, the highest independently tested NRR on the market. Their extra-soft, extra-light foam and tapered design seal gently and snugly without pressure, while the outer surface is smooth, so it doesn't irritate the ear canal. They are bright green for easy compliance checks and 100% PVC-free. With the Plug Station, you can afford to put earplugs in all the places they're needed. Available in 250 and 500 pairs per dispenser, Plug Stations increase compliance, because their high visibility increases awareness so you won't waste time looking for earplugs. The corded model is ideal for food processing and promotes longer use. Uncorded earplugs are available 500 pairs per dispenser and corded earplugs are available 250 pairs per dispenser.
