Custom-made earplugs are designed to be worn repeatedly, often for hours at a time. That makes proper cleaning and storage an important part of keeping them comfortable, hygienic and functional.
Whether you use your earplugs at festivals, at work, while communicating, or while sleeping, a few simple habits can make a big difference.
At NP-ONE, our custom earplugs are supplied with maintenance accessories such as a cerumen pen, cleaning materials and a storage case, depending on the model.
A simple cleaning routine
1. Remove earwax
Use a cerumen pen to carefully remove visible earwax around the earplug and sound channel.
2. Clean the earplugs
Wipe the earplugs with the appropriate cleaning material. Avoid aggressive cleaning products that can damage the material or filters.
3. Let them dry
Make sure your earplugs are completely dry before storing them.
4. Store them safely
Keep your clean earplugs in their storage case to protect them from dirt and damage.
How often should you clean them?
For regular use, clean your earplugs frequently and always give them some attention after heavy use, such as during festivals, sports or long working days.
A few minutes of maintenance once every while can help keep your custom earplugs performing as intended.
Clean. Dry. Store. Repeat.
With the right care, your NP-ONE custom earplugs stay ready for whatever you use them for — from work and communication to music, festivals and sleep.
