Hearing aid maintenance checklist

What steps can I take to increase the lifespan of my hearing aids?

Hearing aids serve as reliable companions in our daily lives. However, how long do they actually last? With proper hearing aid care and maintenance, they can last for years. Regularly cleaning the device, replacing damaged or worn components, scheduling periodic professional cleanings, and taking precautions to protect them all can contribute to extending their lifespan.

1.Protect hearing aids from dirty, heat & moisture

To protect and extend the lifespan of your hearing aid, it is important to take daily precautions against dirt, heat, humidity, and water. During the summer months, hearing aids are particularly vulnerable to water and heat damage. If the device is waterproof, it should be carefully dried after bathing. However, if it is not waterproof, it is crucial to keep it well protected from any contact with water. In the event that the device gets wet due to sudden rain or contact with wet hands, it should be promptly removed, turned off, and the battery should be taken out. Wipe the device with a clean cloth, gently shaking it to remove any moisture that may have seeped in. It can then be left on a piece of paper or an open surface with the battery compartment exposed for a few hours to dry. When it comes to heat, it is important to never leave the device in direct sunlight, as high temperatures and sunlight can potentially cause damage to the outer shell.


It is important to avoid contact between hearing aids and:

  • sunscreen
  • cosmetics
  • spray products

as the substances they contain can potentially damage the devices.

Humidity, although invisible, poses a challenge as it can be difficult to detect. Particularly during summer, as we transition between warm outdoor environments and air-conditioned spaces, the humidity level in the atmosphere increases. This, in turn, leads to increased perspiration on our skin, resulting in more dirt accumulation on our hearing aids. Protecting hearing aids from moisture is relatively simple. When not in use, store them in a cool and dry environment, avoiding placement in areas like bathrooms. Additionally, using specific products designed for dehumidification and drying, such as dehumidifying capsules or special dehumidification boxes, can help safeguard the aids from moisture-related issues.

2. Store your hearing aids safely, at night

It is recommended to remove your hearing aid before going to bed, not only for the well-being of your ear but also for the device itself. Resting your ear on a pillow can cause feedback or potential injury. Additionally, removing the device helps prevent unnecessary battery drain when it is not in use (remember to always turn off the device after removal). When taking off the hearing aid, it is important to store it in the appropriate case rather than leaving it in any random location. Establishing a simple routine can be helpful in caring for your hearing aid. For instance, you can follow a few steps each night, such as:

  • removing the aid
  • turning it off
  • opening the battery door if possible to allow for internal drying
  • placing it securely in the case.

Although this last step may seem trivial, it is crucial to handle the delicate device with care to prevent any potential damage.

3. Changing batteries, domes and ear wax filters

Determining the appropriate time to replace your hearing aid batteries, particularly in the early stages of usage, is generally a simple and straightforward process. It is best to replace the batteries when you start noticing a decline in the aid's effectiveness, such as:

  • reduced hearing
  • lower-quality sound
  • when you begin to experience distorted sound.

While batteries are essential for the device's functionality, they are not the only components that ensure attention to extend the lifespan of hearing aids. Filters and domes are additional components that are essential in maintaining the the hygiene of the hearing aid.

  • Hearing aid domes serve to protect the receiver and enhance sound quality by minimizing sound leakage. Therefore, they should be considered and replaced after a certain period of use since they cannot be effectively cleaned. Once damaged or dirty, it is advisable to replace them promptly to prevent any potential irreparable damage to the other components. The process itself is straightforward and can be easily performed independently.
  • Hearing aid filters serve as a protective barrier against earwax, skin oils, dust, and various types of dirt. They play a crucial role in preventing debris from obstructing the internal components of the hearing aid. However, over time, these filters accumulate debris, which can hinder proper functioning and necessitate replacement. Routine maintenance involves cleaning the filters, which not only extends their lifespan but also ensures optimal efficiency. Nevertheless, even with diligent maintenance, there comes a point when the filter needs to be replaced. You can do this using the dedicated cleaning tool provided at the time of purchase, taking care not to damage the device in the process.

4. Cleaning your hearing aid: remove ear wax

Properly cleaning hearing aids is crucial for extending their lifespan. The necessary tools include:

  • soft cloth
  • cleaning sprays
  • wipes
  • dehumidifying tablets, which effectively remove earwax and maintain clean filters.

A clogged filter is often the cause of device malfunction, so it's important to pay attention to this aspect. While the presence of earwax is normal, its accumulation in the device's opening can lead to sound distortion and irritating whistling. Extended contact with earwax can also damage the aid. To clean hearing aids effectively, it's recommended to establish a daily routine:

  • clean the aids before bedtime
  • ensuring they have time to air out for use the following morning
  • use appropriate tools and substances, such as a soft, dry cloth;
  • open the battery door to allow for air circulation.

5. Schedule professional cleanings

Establishing a daily cleaning routine is essential for maintaining hearing aid hygiene, but it is not a substitute for professional maintenance. While a daily cleaning routine helps to keep the devices clean, it is important to seek the expertise of a trusted hearing care professional for thorough and targeted cleaning.

Professional cleaning effectively removes all traces of dirt, including those that may have accumulated on delicate components like microphones and receivers. This meticulous cleaning ensures optimal hearing quality and extends the life of the hearing aids.

6. Have your hearing and hearing aids checked

Regular hearing checks are crucial even for individuals who wear hearing aids. These assessments serve multiple purposes: they help determine if there is a deterioration in hearing ability and ensure that the current hearing aid is a good fit for the individual's specific hearing needs. Periodic hearing and hearing aid checks are the initial measures to maintain optimal hearing.
