If you know the power of the Exo Terra Fogger ultrasonic nebuliser in a terrarium, you would hardly want to exchange this great piece of terrarium technology for another device. But: The Exo Terra Fogger only does its job reliably and ensures perfect humidity in the terrarium if the membrane can work perfectly. Especially when the Fogger is operated with hard water, the membrane can calcify and must then be replaced so that the ultrasonic nebuliser continues to work reliably. With the replacement membrane for the Exo Terra Fogger, you receive high-quality original accessories from Exo Terra - this membrane fits the Exo Terra Fogger accordingly. However, it can also be used as a replacement membrane in some other ultrasonic nebulisers. Before ordering, please check which ultrasonic nebuliser you use in your terrarium.
