What You Need To Know About The EHEIM Classic
The EHEIM Classic has been around for a really long time. It is a tried-and-tested filter that has sold millions of units throughout its decades-long run, and it shows no signs of slowing down.
And why should it?
This filter is nearly perfect. Sure, it lacks some of the bells and whistles of newer, flashier filters on the market today, but it makes up for it by just doing its job and doing it well.
The Eheim classic is very simple in design – it looks like a green plastic bucket with two holes in it – and this simplicity makes it extremely reliable, durable, and easy to clean.
There are people out there who have been running the same Eheim Classic for over 30 years. These things just keep running, no matter what you throw at them.
This filter is very efficient and consumes very little power. It’s also nearly silent. You barely notice that this thing is on, even if you are running two of them at the same time.
Although there are less expensive filter options out there, the quality and reliability of this filter mean that it is still an exceptional value for the money.
Eheim also offers its own more expensive models, but the simple functionality of the Eheim Classic and the relatively affordable price put it squarely in the sweet spot, and make it the best Eheim canister filter available.

Hands On EHEIM Classic Canister Filter
The Eheim Classic comes complete with canister chamber, spray bar, inlet pipe, hoses, installation accessories and filtration media.
As soon as you pick it up it’s obvious just how well-built this filter is. All of the parts from the canister chamber to the tubing are made of high-quality materials that feel very solid in your hands.
Even the clips that attach the motor head to the canister are made of stainless steel instead of the cheap plastic used by every other manufacturer. That means the clips won’t break, and if they lose their shape you can easily bend them back with pliers.
The Eheim Classic does not have any media trays, which can be a negative for some since you have to keep your media separated when you empty it for cleaning.
But, when filters with media trays get dirty, water tends to find the path of least resistance and bypass the filtration media altogether, which defeats the purpose of having a filter.
Not so with the Eheim Classic!
The simple bucket design with the intake at the bottom and the exhaust at the top means that your tank water will always pass through the filtration media, even if you haven’t cleaned it out in months.
Sure, your flow rate will decrease, but the filter will keep doing its job and keep your water clear. The lack of media trays also means you can fit an insane of amount filtration media in this thing.
One of the few complaints about this filter is that it can be difficult to prime. In this modern age of self-priming canister filters, the Eheim Classic sticks to the more involved process of manual siphoning. But, the process is not complicated.
