A stainless steel body isn't enough: many "steel" kettles still have plastic touching the water. Check the lid, the filter and the water window before you buy.
Where plastic hides in a kettle
- Lid interior. The underside of the lid is often plastic, and steam and condensation run back into the water.
- Limescale filter. Spout filters are frequently plastic mesh.
- Water level window. Many use a plastic strip or tube that the water sits against.
- Seals and gaskets. Often silicone, which counts as plastic under our definition.
Plastic handles, bases and switches don't touch the water, so they matter much less.
What to look for
- A stainless steel or glass body and a steel lid interior.
- A stainless steel mesh filter.
- No water window, or a glass one.
- Clear information from the brand about every part that touches water.
The simplest option
A stovetop kettle, all steel with a wooden or steel handle, has no electronics and usually no plastic in the water path.
Why it matters
A kettle heats water to 100°C several times a day. Heat is the main driver of particle release from plastics, which is why this swap ranks high. See the full swap: plastic kettle → steel kettle.
