Exo Terra Reptile Incubator Unit Replacement Fogger
Restores humidity control in an ageing incubator. This is the genuine Exo Terra replacement USB humidifier for the Exo Terra Precision Incubator PRO – the fogging disc that creates the mist keeping egg-chamber humidity up around your incubating clutch. Foggers have a working life and eventually need replacing to keep humidity climbing to where your species needs it.
Key features
- Genuine fit – the correct replacement fogger for the Exo Terra Precision Incubator PRO.
- USB-powered – connects to the USB port on the rear of the incubator's LED display, drawing power from the incubator itself rather than a separate plug.
- Floats in place – sits on the water reservoir in the foam insert rather than needing to be fixed down.
- Roughly 800 working hours of service life under normal use, longer if run on demineralised or purified water and kept below maximum humidity.

Fitting
Connect the USB plug to the port on the rear of the incubator's LED display, place the fogger in the central opening of the foam insert, then prime it: add water, turn it upside down and shake off the excess, and set it flat to float.
Care and maintenance
Running the fogger on demineralised, reverse-osmosis or purified water – rather than tap water – extends its working life, as does keeping the chamber closer to 70–75% relative humidity rather than the maximum 95% the incubator can reach.
Warranty and delivery
Covered by the manufacturer's standard warranty against faults, in addition to the consumer guarantees you're entitled to under Australian Consumer Law.
Common questions
How do I know it's time to replace the fogger?
Exo Terra rates the fogger at approximately 800 working hours; a drop in mist output or chamber humidity that doesn't respond to cleaning is the usual sign it's due for replacement.
Will any USB humidifier work, or do I need the genuine part?
This listing is the genuine Exo Terra fogger sized and shaped to fit the foam insert in the Precision Incubator PRO.
Does using tap water damage it faster?
Mineral content in tap water shortens working life compared with demineralised, reverse-osmosis or purified water.
