I wouldn’t run an external without one.
Pre filters make life much easier when keeping your water quality in optimum condition and crystal clear. Added bonus is it also picks up juvenile snails that you can remove when you’re rinsing your filters out. I wouldn’t dream of running an external filter nowadays without adding an Eheim
Pre Filter into the mix.Read full review

Filter Efficiency
Great addition to the filtration of your tank. Prevents solid waste and sand from entering your filter meaning cleaning periods of your filter can be extended.
Clean this pre filter sponge regularly though as it gets clogged quickly and reduces water flow from the filter outlet.
I keep Malawi’s but even I was surprised at the amount of waste that came out of these two sponges when I cleaned them.Read full review

Eheim pre filter
First class product, easy to fit and adds extra filtration to your tank. if you already use Eheim internal filters you can swop the canisters and foam inserts from them, handy to seed new tank or emergency tank. I had another brand of external filter and they make a inline pre filter it was messy to clean because it's outside the tank fitted to the supply pipe work and you always had water spillage disconnecting and filling back upRead full review

Eheim pre filter
The Eheim pre filter is of a high quality with two cleanable sponge filters inside. They are easy to remove and wash out. The filter will fit 16 and 22mm suction pipe with a two diameter taper inside the connecting pipe. The filter is a bit bulky and unsightly but you can hide with a tall plant in front. I purchased as I have started to keep fresh water shrimp and didn't want them all ending in the filter. It also saves cleaning out the big filter so often as this catches the worst before it gets there. Its a easy job to clean these out and I wash these out once a week.Read full review

Eheim says it all !
I bought this pre filter as an add on to my Eheim main filter for my reef tank. A wonderful thing that traps most of the waste before going into my main filter making life easier! Can also be used for freshwater.Read full review

Eheim pre filter
If you have never used a pre filter you will not believe the difference it makes when you come to clean your external filter. This’ll save you time. I cannot recommend this unit enough.
