Eheim Pre-Filter Coarse Filter for Aquarium Canister Intake

The Eheim Pre-Filter (Coarse Filter) is an add-on unit that attaches to the intake line of your external canister filter. It catches coarse debris and sediment before the water reaches the main filter, helping keep the canister media cleaner for longer.

Its cylindrical design with a large surface area sits on the aquarium floor and draws water in from around it. Two easy-to-remove baskets provide mechanical filtration and also give beneficial bacteria a place to grow. By helping protect the biological media inside your external filter from early clogging, it can extend maintenance intervals and support overall filtration efficiency.
