Why swap
Plastic kettles hold water at 100°C many times a day. Heat is the main driver of particle release from plastics.
What to look for
- Stainless steel or glass body
- Steel lid interior and steel limescale filter
- No plastic water-level window, or a glass one
- A stovetop kettle is the simplest fully plastic-free option
Watch out for
- Many "steel" kettles have a plastic lid interior, filter or water window touching the water
- Check the spout filter — it is often plastic mesh
