To maintain the stated sound attenuation performance of your earmuffs, it is important to regularly replace cushions and inserts. Under “normal use,” you should replace the hygiene kit at least twice per year. For proper performance, always use genuine MSA replacement parts. We offer the proper replacement kit for your specific MSA hearing protector.
