Learn how to replace your kettle water filter quickly and correctly. This step-by-step guide covers the process, common mistakes, and when to change the filter.
Quick Answer
To replace your kettle water filter, remove the old filter from the spout or lid, rinse the new filter under cold water, insert it securely, and run a full boil cycle before use.
Why You Should Replace Your Kettle Filter Regularly
A clogged or old water filter can reduce water flow, affect taste, and allow limescale to build up inside your kettle. Replacing it every 2-3 months keeps your water clean and your kettle running efficiently.
Even if you descale your kettle regularly, the filter traps particles that descaling alone won't remove. A fresh filter also helps prevent scale from reaching your cup.
Choosing the Right Replacement Filter
Russell Hobbs kettles use different filter types depending on the model. Honeycomb and Groove ranges use a standard mesh disc filter, while Purity™ kettles require a spout-mounted cartridge. Using the wrong type can cause poor fit or reduced filtration.
Check your kettle's model number (usually on the base) or look at the shape of the old filter to pick the correct replacement.
Step-by-Step Filter Replacement
- 1. Unplug and empty the kettle: Make sure the kettle is unplugged and completely cool. Pour out any remaining water and remove the lid. Never work on a plugged-in or hot kettle.
- 2. Remove the old filter: For disc filters (Honeycomb/Groove), gently pry the mesh disc out of its slot using your fingers or a soft tool. For Purity™ spout filters, twist the cartridge counter-clockwise until it releases. If the old filter is stuck, soak it in warm water for a minute to loosen any mineral deposits.
- 3. Rinse the new filter under cold water: Hold the new filter under cold running water for about 10 seconds. This removes any loose dust or packaging residue. Do not use soap or detergent – they can leave a taste.
- 4. Insert the new filter securely: For disc filters, press the new mesh disc firmly into the slot until it sits flat. For Purity™ spout filters, push the cartridge into the spout opening and twist clockwise until it clicks into place. A loose filter may rattle or allow unfiltered water to bypass.
- 5. Run a full boil cycle and discard the water: Fill the kettle to the maximum level, boil it, and pour the water away. This flushes out any remaining manufacturing residues and ensures the filter is seated properly. The first boil may produce a slight plastic smell – this is normal and will disappear after one or two cycles.
