Designed for optimal comfort and protection, the NRR 30 Canada Class A(L) LPF-30 earplugs by Howard Leight are a reliable choice for those exposed to hazardous noise levels. With a Noise Reduction Rating (NRR) of 30 and a SNR of 34, these earplugs effectively attenuate sound while ensuring a snug fit, thanks to their contoured T-shape design which is particularly suited for individuals with smaller ear canals. Crafted from low-pressure polyurethane foam, they expand gently for long-term wear, making them ideal for various industries including forestry, construction, and law enforcement. Available in multiple packaging options, including bulk refills for convenient dispensing, these earplugs also feature a smooth, soil-resistant skin that prevents dirt accumulation, ensuring they remain hygienic and ready for use.
