Plastic free is a term that gets used loosely, and it's worth being precise about what it covers. On a kettle, the parts that matter most are the ones that actually touch the water while it heats: the tank interior, the spout channel, and the underside of the lid. A kettle can be marketed as plastic free while still having a plastic seal around the lid or a plastic filter clipped inside the spout, so it's worth checking specifically rather than taking the label at face value. The kettles in this range use a glass body with a stainless steel tea infuser, and a full stainless steel interior with a stainless steel inner lid, so every surface the water contacts during boiling is glass or stainless steel, not plastic.
Why It's Worth Choosing a Plastic Free Kettle
Boiling water is one of the more demanding things you can do to plastic, since heat speeds up the release of microplastics and chemical residues from any plastic surface it touches. A kettle with a glass or stainless steel interior avoids that altogether, which matters if you're filling baby bottles, making tea or coffee daily, or simply prefer not to have hot water sitting against plastic before you drink it. Stainless steel and glass are also easier to keep genuinely clean, since they don't hold onto odours or stains from tea, coffee, or mineral buildup the way some plastic components can over time.
