3. How to maintain the device clean

a. Cleaning Eartips

Pets have a lot of fur in their ears, which can cause hair to stick to their Eartips and Earcaps.
When this happens, remove the hair from the Eartip and the Earcap. If you prefer, you can separate the Eartip and Earcap and wash them under water, dry them, and reattach them.

b. Removing furs

Remove furs on DearBuds PE with tweezers, tape, or a vacuum.

c. Cleaning mode

Performing the cleaning mode in 'Settings' will drain any remaining humidity and dust within the device.

Place DearBuds PE horizontal and run the cleaning mode.

(Cleaning mode operates for 200seconds.)


In DearBuds PE, if there is a noise during operation, it is a signal to run the cleaning mode.

Once Dearbuds PE fan has been cleaned, it will spin evenly and the noise should disappear.

4. Tips for using the device 

*When DearBuds PE makes noise

The device should be set to cleaning mode if unusual noises occur during operation.

When DearBuds PE is in cleaning mode, the fans are aligned and the noise gets reduced.

*Tips for human
Using a cotton swab pushes earwax into the ear canal, which can damage the delicate skin of the external ear canal.
Instead, DearBuds PE provides gentle ear dehumidification.

*Tips for pets

a. Getting used to unfamiliar devices

If it is their first time looking at an unfamiliar figure, pets may be wary.

It is recommended to use DearBuds PE to pets after a certain period of getting used to it.

b. Finding your way around the device (from low mode)

With DearBuds PE, your pet will easily adapt to the low decibels.

Start by dehumidifying it with L1 mode. Once you get used to it, please switch to L2 and A mode.

c. Using the device wisely – Behind the Ear

When DearBuds PE first appears in your pet's view, they may feel frightened.

It is possible to dehumidify longer without creating discomfort for your pets when the dehumidifier is brought from behind their ears.

d. Select a place free of disturbances

Dehumidify in a place where pets cannot move or run away from outside interference.

e. Compensate properly after dehumidifying the ears

Your pets will be more willing to dehumidify your ears if you reward them with snacks after you dehumidify them.
