Pura-Fit® earplugs are tapered so they are easier to insert in most ear canals. Plus their longer shape make them easier to grasp. Pura-Fit earplugs are designed for increased compliance and fewer complaints. The special foam is formulated for softness and comfort, and the outer surface is smooth, so it doesn’t irritate the ear canal. All Moldex hearing protection is independently tested to ANSI S3.19-1974 by Michael & Associates, Inc., State College, PA so you know you’re getting excellent protection against industrial noise.
