Innovative engineering and automation has allowed Moldex to create Alphas—a superior reusable earplug at a very competitive price. Give workers the protection they need and the comfort they deserve, all while lowering your overall hearing protection program costs. Alphas’ high Noise Reduction Rating (NRR 27dB) provides protection for most noisy environments. All Moldex hearing protectors are independently tested to ANSI S3.19-1974 by an independent, accredited laboratory, so users can be confident in the protection they are getting, when worn properly. Never settle for manufacturer-tested NRRs!
