Wax Guards for Hearing Aids: Which Part Fits and When to Change It

What a wax guard is, in the makers' own guides

On the aids covered by the guides read for this page, the filter sits where sound leaves the speaker. ReSound's user guide for its rechargeable Nexia receiver-in-ear aids places it at the inward end of the receiver or custom earmold, and says it helps keep earwax away from the aid's components. Oticon's instructions for its Opn miniRITE aids describe a white filter attached to the end of the speaker, where the earpiece goes on.

The names differ more than the idea. Phonak's US guide for the Audéo I-R calls the part "earwax protection" and exchanges it with CeruStop on the regular receiver. Oticon's part is the ProWax miniFit filter. ReSound ships its filters already loaded on small tools, in a box of 8. Signia lists each guard under a part number, such as the miniR Wax Guard 10962332.

If you wear a custom mould, check who changes the filter before you order. Oticon's guide says that with a mould, the hearing care professional replaces the wax filter in the speaker.

Are all hearing aid wax guards the same?

No. Each maker in this table sells its own guard, and one maker can use two systems on a single model. Phonak's Audéo I-R guide has CeruStop on the regular receiver and the HF3 wax filter, with its own dispenser and changing tool, on the ActiveVent receiver with SlimTip.

Signia's wax guard guide, an Australian product document, splits its parts by receiver generation. The miniR Wax Guard 10962332 fits the miniReceiver 2.0, Silk and Active. The QuickGuard Pack 10962504 fits the Click Mould 2.0, the HP Shell 2.0 and Insio aids. The WG 3.0 NanoCare 10993649 goes with the miniReceiver 3.0, ThinTube 3.0, Power ThinTube 3.0 and Ear Mould 3.0. Signia's training guide for hearing care professionals adds one more name, CeruStop XL, for the wax guard of its 3.0 HP receiver.

The Signia guide lists the 2.0 and 3.0 parts on separate lines and gives no rule for using one in place of the other, so the table keeps them apart. Jabra Enhance sells one bundle, a pack of 48, which its page says fits all Jabra Enhance Select aids and earlier models. The table above sets every part beside the receiver or model it fits.

How often to change hearing aid wax guards

Of the four makers whose guides we read, only Phonak prints a number. Its Audéo I-R guide says to replace the earwax protection every 4 weeks on a regular receiver and every 2 weeks on the ActiveVent receiver, and adds that your hearing care professional can advise a different cycle. It also asks you to check the protector regularly and exchange it sooner if it looks dirty or the volume or sound quality drops.

The others tie the change to a condition. Oticon's guide says to replace the ProWax miniFit filter when it becomes clogged, or to contact your hearing care professional. ReSound's says you must replace the filter on a regular basis and sends you to your professional for how often. Signia's support FAQ says to replace wax guards regularly and that the frequency depends on the wearer.

So a calendar applies on the Phonak model, and on the other brands the schedule is a condition you watch for or a cycle your professional sets. Wearers of Oticon moulds leave the speaker filter to the professional.

How to use the tool that comes with the filters

Each system comes with its own small tool, and the three designs described in the guides differ. Phonak's HF3 changing tool has a screw end that removes the used filter and a forked end that picks up a new one from a rotating dispenser; the dispenser also has a slot for used filters.

Oticon's ProWax miniFit tool has two pins: an empty one that you push into the old filter and pull out, and one carrying the new filter. Once the new filter is in, the tool is thrown away. ReSound's tools follow the same idea, with a removal tip at one end and a replacement tip holding a white filter at the other, and they come in a box of 8.

The pictures and the exact sequence are in each model's guide, which is the document to follow. Daily cleaning of the aid and its earpiece is covered on how to clean hearing aids.

What wax guards cost, and how they are billed

Our dated price readings hold no wax guard pack yet, so this page prints no shelf price. Jabra Enhance's bundle page carries a condition worth checking before you pay: certain customers who bought before 5/14/2024, and Unlimited Plan customers, may be eligible to get its pack of 48 at no cost.

On a claim, supplies without a code of their own go under V5267, which the October 2026 CMS code file describes as "hearing aid or assistive listening device/supplies/accessories, not otherwise specified". Nationally, Medicaid paid $73.66 per V5267 claim line in 2023-2024, across 18,257 lines. That covers every supply and accessory billed under the code, so it is not a wax guard price. Codes and payers for the other accessories: hearing aid accessories.
