OASE FiltoSmart Thermo 100 is a compact external canister filter with an integrated heater, designed for aquariums up to 100 litres. It combines two essential pieces of equipment into one elegant unit — keeping your tank clutter-free while delivering reliable 2-stage mechanical and biological filtration.

The built-in HeatUp heater maintains a precise and uniform water temperature, eliminating the need for a separate in-tank heater. Water flows evenly through the filter media, ensuring consistent heating throughout the aquarium.
