Need a replacement cord or adapter? Learn which Duux power accessory fits the Neo Humidifier and Tube, and how to check compatibility before you buy.
Quick answer
The Duux Power Cord Tube fits Tube models DXPU03 and DXPU04, while the Neo Humidifier Power Adapter fits the Neo Humidifier DXHU31. These accessories are model-specific, so check your device's type number before ordering. If you're unsure, look for the label on the base or plug.
Why model numbers matter more than product names
Duux uses similar names across generations, but a power accessory that fits one type often won't fit another. The safest approach is to find the exact type code printed on your device — usually on a sticker underneath or near the power input. For example, the Neo Humidifier Power Adapter is designed for type DXHU31, and the Power Cord Tube is made for types DXPU03 and DXPU04. If your device's type isn't listed, that accessory is not confirmed to work.
What to check before buying a replacement power cord
Start by confirming the connector shape and voltage. The Power Cord Tube is a white cable specifically for the Tube, so it matches the Tube's power input. If you try to use it on a different device, the plug may not fit or the cable may not be rated for the same electrical load. When in doubt, compare the old cord's connector to the product photos and check the type code. If your device isn't a Tube DXPU03 or DXPU04, this cord isn't the right match.
How to tell if your Neo Humidifier needs a new adapter
If your Neo Humidifier won't turn on, first check the wall outlet and the adapter's connection to the humidifier. A damaged cable — frayed, bent, or with exposed wires — should be replaced immediately. The Neo Humidifier Power Adapter is a direct replacement for the DXHU31 model. It's white and matches the original. If your humidifier is a different model, this adapter won't fit; you'll need to find the correct one for your type.
Can you use a universal adapter instead?
Universal adapters can work if they match the voltage, polarity, and plug size, but they often don't fit securely and may not meet the same safety standards. For a device like the Neo Humidifier, a dedicated adapter is the safer choice because it's designed for that model's power requirements. The same goes for the Power Cord Tube: it's made for the Tube, so it's a straightforward swap. Using the wrong adapter can risk damage to the device or create a fire hazard.
Where to find your device's type code
The type code is usually printed on a rating label on the bottom or back of the device, or sometimes on the original power supply. It's a short alphanumeric code like DXHU31 or DXPU03. If the label is worn or missing, check your manual or the original packaging. Without the type code, you can't be certain which accessory fits, so it's worth taking a photo of the label before you shop.

- Fits only the Neo Humidifier type DXHU31. Check the label on the base of your humidifier. If your model is DXHU31, this is the correct adapter.
- Power Cord Tube
- Fits only Tube types DXPU03 and DXPU04. The connector and cable length are specific to these models. If your Tube is DXPU03 or DXPU04, this cord will work.
