Hearing Aid Wax Guards: What You Should Know


Willy Stewart


  • Hearing aid wax guards protect your hearing aid from damage caused by moisture or wax
  • Typically, hearing aid wax guards should be changed once a month
  • It is important to use a wax guard suitable for your device as the size of a wax guard can vary. If the wax guard doesn’t fit properly, it could fall out or become stuck in your ear
  • BTE hearing aids have a tube which can also become blocked with wax

One of the most common causes of hearing aid damage is either not using a hearing aid wax guard or using the wrong one for a particular device. Where damage occurs, the quality and level of sound received can be reduced. Using the right wax guard helps to maintain the effectiveness and longevity of your hearing aids. Most importantly, it ensures the sound you rely upon is crisp and clear.

What is a Hearing Aid Wax Guard?

A hearing aid wax guard is a small filtered stick that repels ear wax and excess moisture which could damage the hearing aid.

Why do I need a Wax Guard for my Hearing Aid?

Your hearing aid receiver, like any audio equipment, does not react well with moisture or sticky substances. Wax blocks the passages which enhance & transfer sound to the user. It can then begin to damage the device itself through prolonged exposure. Ear wax causing moisture damage is one of the most common reasons hearing aids require repair.

What Wax Guard Should I Use for My Hearing Aid?

Hearing aid wax guards can differ in size and shape, it is important to remember that they are not all the same. Different manufacturers can create wax guards specific to their models. If you don’t use the correct wax guard for your hearing aid, there is a risk the wax guard could fall out or become lodged in your ear.

At Wholesale Hearing, we stock Cerustop hearing aid wax guards. Cerustop wax filters are compatible with some Phonak, Resound, and Unitron hearing aids. If you are unsure what wax guard will be suitable for your exact model, one of our team will be happy to help find the right one for your hearing aid.

How Do I Replace a Cerustop Hearing Aid Wax Guard?

To replace a Cerustop wax guard, remove the rubber cover from the hearing aid earpiece. Using the filter stick, retract and replace the small white fitting with the new wax guard element from your replacement Cerustop supply. Close the hearing aid earpiece with the rubber cover.

How Often Should I Change the Wax Guard in my Hearing Aid?

Typically the wax guard in your hearing aid should be changed once a month, although it is wise to check more often to ensure optimum performance. You should be able to tell if a wax guard should be changed sooner if the volume drops or sound is distorted from your hearing aid.
