What are the foam earplugs made of and do they contain latex?
The earplugs are made of polyurethane foam. The “latex” in our foam earplugs is not natural latex, it is a synthetic latex technically called an emulsion polymer. It has the same properties as latex (water based, adhesive, etc.) but does not have the enzyme problem associated with natural latex.
If, in the extremely rare instance you should experience any type of rash or skin irritation while using this product, please discontinue use immediately. Consult your doctor or go to your local medical emergency room if you believe you require immediate medical attention.
Can the earplugs be cleaned?
No. If these earplugs become soiled, they should be disposed of.
Besides reducing noise, can these earplugs be used to seal out water?
No. These earplugs were specifically designed to provide superior protection against noise. For water protection, we recommend that you try one of Mack’s® moldable silicone or pre-molded flanged earplug products.
Are there any application tips to help me get a proper seal with the earplugs?
Please re-read the directions on the package and check out our instructional video on our product detail page to ensure you are getting the best fit and performance. The earplugs should be inserted so that there is just enough of the earplugs sticking out of your ear canals that you can easily grasp them with your thumb and forefinger for removal. Be sure to insert the plug while pulling (with the opposite hand) up and back on the outer ear to straighten the ear canal. If you are still unsuccessful with a plug that has now absorbed some sweat from the ear canal, try another, unexposed plug. A totally dry plug will retain its compressed shape and rigidity slightly longer, making it easier to insert. A sign that the earplug is sealing your ears properly is that your voice will sound more internal and exaggerated. Following these directions and tips with help ensure a proper seal and noise reducing benefits as well as help keep the earplugs securely in your ears.
