How do you practically change the filter. Do you just twist the old one and screw in the new one (and reset the electronic counter?)

Yes, just unscrew the old filter, no need to turn the water off as the filter head has a non return valve inside, then simply screw new filter in, you will get hiss as the filter pressurises as you screw the last few threads, only tighten hand tight! Then flush through about 3 litres, it will splutter a bit as it gets the air out. Then reset your counter.

How often does the filter need to be changed.

Hi Flossy,this Filter is for a capacity of 600 liters.Kind regardsJenny Hetkamp and the KILEAN team

Can I still use the boiling water and hot and cold water without resetting new filter?

I feel you need to ask Grohe 😀. I use only Grohe red for boiling water. Therefore only reset once I have changed the filter! I use hot and cold water as I would normally.

I have a grohe blue 600 the filter that has arrived is a lot smaller. will it still work or should i reorder?

It should work, ours did. It just appears to be smaller but does the same job and of course takes up less room. Best of luck, I accept no liability if it is not up to your expectations.
