Moldex hearing protection is designed for comfort with features like the air bubble in the tip of our Rockets reusable plugs and the soft, smooth foam of our foam ear plugs. Another Moldex exclusive is our patented PlugStation. It's a convenient dispenser that increases compliance by putting plugs where you need them and wherever hearing protection is required. High visibility dispenser increases awareness for your hearing conservation program because they are affordable enough to be placed near every work area. PlugStations eliminate the mess of individual bagged packaging because ear plugs drop right into the palm of your hand. Clicking mechanism ensures easier use and dispensing. Moldex NRR 33 earplugs have the highest independently tested NRR, tested to ANSI S3.19-1974 by Michael & Assoc., Inc., State College, PA., a truly independent testing laboratory.
