The 350T thermo filter combines external aquarium filtration with integrated temperature control, making it an excellent all-in-one solution for freshwater aquarium setups.

High-Performance External Aquarium Filtration

The Eheim Professionel 4+ 350T is designed to provide reliable and efficient mechanical and biological filtration. Its high flow capacity and large filter volume help maintain clean, healthy aquarium water while its low energy consumption makes it economical to operate.

The square-shaped canister provides stability and allows the filter to fit neatly into corners, making efficient use of space in your aquarium cabinet.

Xtender Control Function

The innovative Xtender function helps extend the intervals between filter cleaning. When the fine filter pad becomes blocked, the Xtender control can increase the flow rate by redirecting water while maintaining biological filtration.

This allows the filter to continue operating effectively and can postpone filter cleaning for a few days, providing greater convenience between maintenance sessions.

Self-Priming System

The integrated self-priming aid makes starting the filter quick and easy. There is no need for complicated manual suction methods, helping simplify installation and filter maintenance.

Safety Hose Adapter

The safety hose adapter features a tap unit with two hose connectors. For additional safety, the hose adapter can only be released when the valves are closed, helping prevent accidental water release during maintenance.

Integrated Prefilter

The top prefilter captures larger dirt particles before they reach the main filter media. The prefilter can be cleaned regularly, helping extend the maintenance intervals between full filter media cleaning.

This design reduces the amount of larger debris reaching the main filtration stages while helping maintain consistent filter performance.

Easy-Clean Filter Baskets

Individual filter baskets allow mechanical and biological filter media to be arranged conveniently within the filter. The baskets can be easily removed, while the contents can be cleaned using the integrated Easy Clean grid.

This makes filter media maintenance straightforward and helps simplify routine aquarium filter cleaning.

Quiet and Reliable Operation

EHEIM high-performance bearings and ceramic axles are designed to provide quiet operation, long service life, and excellent durability. The Professionel 4+ 350T is engineered for reliable continuous operation in home aquarium systems.
