There is no single schedule for every filter
Drinking-water elements and shower cartridges are different products. Their replacement guidance can depend on the material, water conditions and amount of use. Follow the instructions supplied with your model.
Know which replacement you need
The carbon replacement pair contains two black elements with threaded connectors and securing nuts. Check the system model and connector dimensions before ordering. White add-on cartridges are not included.
The shower replacement cartridge is a separate item for the Helfy 15-stage shower filter. It is not interchangeable with the drinking-water elements.
Keep a simple record
Write down the fitting date and retain the care guide. This makes it easier to follow the recommended service interval and reorder the correct replacement.
Give your system regular attention
Follow the cleaning and preparation instructions provided. If anything changes unexpectedly or you are unsure which element to fit, contact Helfy Hub before continuing.
Ask when you are unsure
A model name and a clear photo of your existing filter can help us identify the right replacement. We are here to make the next step simple.
