Water filter does what it says on the tin. Like others I really struggled to remove the old unit, until I discovered what when you've removed the (red in my case) retaining clip, you need to push the grey collet INTO the filter as you remove the pipe, to release it. Just pulling on the pipe will only make the collet grip harder and will potentially stretch the pipe.

Samsungs instructions tell you to install it the correct way around as shown by a direction flow arrow on the filter... That does not exist.

I have seen many comments regarding direction of flow not indicated. Well I have to dispute this. It is clearly marked on the label ..
