You can afford to put earplugs in all the places they're needed. That's because you pay only for the earplugs, not the dispenser. The PlugStation® increases awareness and compliance, because you can see where it is, and it is easy to take care of. You don't refill it. You just throw the dispenser in a recycle bin, mount another PlugStation®, and there's no more paper or poly bag mess all over the place. Probably the best thing about PlugStation® is that you'll be able to get SparkPlugs® or Pura-Fit® soft foam earplugs wherever you want them. Both rated NRR 31dB. PlugStation® is available in two sizes - 250 and 500 pairs.
