It can be also easy to clean!
small update (08/17/2013)
I can filter unfortunately not really recommend. After about a 3/4 year the pinion is now followed by the water wheel turns totally sanded. Now the wheel wobbles and skin constantly against the plastic housing. This not only reduces the flow or the speed but is also extremely loud and disturbs tremendously in the long run.
So one probably should prefer but look for another filter - at least I've now done it, ...
