The Franke 04 'High Flow' cartridge is a superb alternative to the Franke 03 when an improved water flow is required.

Manufactured from advanced carbon block with a pre-filter wrap and mesh, the Franke 04 is an excellent alternative in situations where the ceramic section of the Franke 03 is clogging too frequently due to higher than average levels of sediment.  The Franke 04 is especially effective against a range of possible chemical  contaminants and heavy metals , including chlorine and lead.

Please note the Franke 04 is the standard replacement filter cartridges for Franke FilterFlow customers in Northern Ireland.

Your Franke 04 cartridge should be replaced every 6 months.

What will the Franke 04 cartridge remove?

The Franke 04 is especially effective against a range of possible chemical  contaminants and heavy metals , including chlorine and lead. It also offers cyst reduction.

How often should I be changing my Franke 04 cartridge?

We recommend that Franke 04 cartridges are changed every 6 months. Carbon works by adsorption and will gradually becomes less effective as it becomes loaded with contaminants.  Please bear in mind, however, that the period between cartridge replacements is not guaranteed.  Everyone's water is different and in areas with a higher level of turbidity (dirt, sediment etc.) it is possible that more frequent cartridge changes will be required.

My kettle seems to be constantly full of limescale and we often notice a filmy substance on the top of tea and coffee, too.  Is it possible to switch to a filter cartridge that will stop this?

Yes and no!  50% of UK households are in hard water areas - but the actual hardness of water still varies dramatically from home to home.  Franke standard filter cartridges do not tackle hard water because as a product that is intended to deliver healthy, great-tasting drinking water, calcium and magnesium (the causes of limescale) are regarded as essential! 

However, we do recognise that - whilst harmless - the aesthetic appearance of scum on hot drinks is not desirable.  As such, you might wish to try switching to a Franke 06 filter cartridge.  The Franke 06 combines granular activated carbon with a de-alk resin to tackle chemicals such as chlorine and heavy metals e.g. lead and it works to reduce the residues of limescale.

The flow of my filtered water seems to becoming slower and slower - what could be the problem?

With a Franke 04 cartridge, an increasingly slow flow is an indication that the exterior of the cartridge has become blocked with contaminants.  The Franke 04 cartridge is not cleanable and a new cartridge will need to be installed. 

I think I can see miniscule black specks in my filtered water - what are they?

You should have no need for concern - especially if you have recently changed your filter cartridge.  The black specks are tiny, harmless particles of carbon that are residues from the manufacturing process.  Flush them through by allowing your tap's filtered flow of water to run for a few minutes until they disappear.

What should I do with used filter cartridges?

You can dispose of old cartridges in your normal household waste.  Alternatively, we welcome the return of spent cartridges so that we can recycle them responsibly.  Please allow used cartridges to dry naturally before returning them to us in your new cartridge's packaging.
