Find the right Russell Hobbs kettle filter for your model. Check model numbers and choose the correct anti-scale filter for Mode, Retro, or Textures kettles.
Quick answer
To find the right filter, check the model number on the base of your kettle and match it to the compatible filter listed below. For Mode kettles use the Anti Scale Filter for Mode Kettle, for Retro kettles use the Water Filter for Retro Kettles, and for Textures kettles use the Anti Scale Filter for Textures Kettle.
Why model numbers matter
Each Russell Hobbs kettle range uses a slightly different filter fitting, so a filter designed for one model won't necessarily clip into another. The model number is printed on the underside of the kettle base and usually starts with 21 or 22. Matching that number to the filter's compatible list is the most reliable way to avoid buying the wrong part.
If you've lost the manual or the model number is worn, check the kettle's base for a silver sticker or embossed code. You can also look up the original product page in your order history or contact Russell Hobbs support with a photo of the base.
What happens if you use the wrong filter
A filter that isn't designed for your kettle may not sit flush, which can let scale pass through or cause the lid to close poorly. In some cases, the filter might even pop out during pouring. Using the correct filter keeps your water clean and your kettle working as intended.
If you're between two similar filters, always double-check the model number. The Textures and Mode filters look alike at a glance, but they are not interchangeable.
Decision rules for choosing your filter
- Check the model number: Look on the underside of the kettle base for a number like 21400 or 21271. Write it down before shopping. If the number is missing, contact support or check your order history.
- Match the model to the filter: Use the Anti Scale Filter for Mode Kettle for models 21400, 21401, 21400-70. Use the Water Filter for Retro Kettles for Retro models. Use the Anti Scale Filter for Textures Kettle for models 21271, 22591, 21270-70, 22591-70. When in doubt, choose the filter that lists your exact model number.
- Buy the right quantity: Filters are sold individually. If you use your kettle daily, consider ordering a spare so you always have a clean one ready. Replace the filter every 2–3 months or when you notice scale in your water.
