Oase internal aquarium filters provide highly efficient water filtration and are incredibly easy to clean and maintain, making them ideal for both first-time and experienced aquarium owners. We also offer a wide variety of Oase external filters to suit your needs.

Removing excess waste and toxins from aquarium water is essential for keeping your fish and plant life healthy and happy, so efficient filtration is needed. Oase internal filters sit inside your aquarium and help maintain water quality for tanks holding up to 200L.

Oase internal filters to suit all compact aquariums

From small aquariums holding just 25L, to larger 200L tanks, Oase internal filters are budget-friendly and provide efficient filtration to remove harmful toxins, chemicals and debris. Internal filters like the Oase range draw water and debris from the aquarium using an internal pump, before feeding it through the filter media and returning the clean water to the tank.

Our range of Oase filters includes the Oase BioPlus and BioCompact models, which combine multiple filter media types for several stages of filtration. Some of our Oase filters can be installed horizontally as well as vertically, meaning water depth need not be an issue, and all Oase internal filters run quietly and efficiently. Some of our BioPlus models also include a built-in water heater, saving you both money and space when it comes to equipment.

Oase has ensured its internal aquarium filters are conveniently low-maintenance with easy to access filter compartments and modular designs, while ensuring no compromise on quality and efficiency.
