A plastic-free kettle guide should check the complete water-contact pathโand, if your standard excludes it, the steam and condensation path too. โBPA-freeโ does not establish that a kettle has no plastic contact, and a stainless-steel body alone is not enough to tell. The models below are compared using manufacturer disclosures; those claims are not independent product audits.
Before buying, decide whether silicone is acceptable to you, then verify the exact modelโs lid underside, spout or strainer, sensor area, and seals. Capacity, temperature controls, cleaning access, and how clearly the maker describes materials matter alongside the body material.
What โPlastic-Freeโ Should Mean
There is no single definition that fits every shopper. A strict standard excludes plastic from surfaces that contact water, hot water, steam, or condensation that returns to the kettle. Some shoppers also exclude silicone; others treat it as a distinct material. State your boundary before comparing products.
Ask about the kettle wall and base, spout or strainer, temperature sensor, lid underside, and seals. โBPA-freeโ addresses only a particular chemical claim; it does not prove that every water- or steam-contact surface is free of plastic. Likewise, a makerโs material description is not the same as an independent audit.

Named Kettles Compared
| Model | Maker-disclosed materials or features | What to verify |
|---|---|---|
| Saki Luna | Saki describes stainless steel and borosilicate glass in the water-contact path. Saki also says an outside lab tested a sample Luna for BPA, phthalates, PFAS, and heavy metals. | Check the exact current model and request the test documentation. Sakiโs reported sample test is not a general finding about all kettles or production units, and the surfaced information gives no numerical results. |
| GRAEF WK350 | GRAEF describes water contact as glass or stainless steel. Its listing specifies a 1 L capacity, temperature settings, 30-minute keep-warm, boil-dry protection, and overheating protection. | Confirm details in the exact modelโs current listing or manual and check regional availability. These are maker specifications. |
| Mueller 1.8 L glass kettle | Mueller lists a glass body, stainless-steel filter, BPA-free and PTFE-free claims, automatic shut-off, and boil-dry protection. | The cited page does not settle every water- and steam-contact surface. Treat it as a glass-body comparison, not as a confirmed strict plastic-free choice. |
| Aarke temperature-control kettle | Aarkeโs surfaced product wording describes stainless steel and a silicone sensor seal in the water path; it also says steam may contact silicone and plastic in the lid structure. Another surfaced Aarke page says no plastic contacts drinking water. | The wording conflicts across pages. Ask Aarke to clarify the exact modelโs lid and steam-contact surfaces before treating it as plastic-free. |
| Fellow EKG | Fellow says its current EKG models are not fully plastic-free: the maker describes a 304 stainless-steel interior, a silicone probe ring, and polypropylene in components including the lid, base, and handle. | Useful counterexample: a stainless interior does not establish a fully plastic-free kettle. |
| ZWILLING Enfinigy 1.7 L glass kettle | ZWILLING describes glass and stainless steel, plus a BPA-free silicone inner-lid seal, with no other plastic contacting water. | It includes silicone, so it is not an all-glass/all-metal contact path for shoppers who exclude silicone. |
| Xiaomi Double Wall Electric Kettle | Xiaomiโs FAQ identifies a 316L stainless-steel interior and says water-contact materials meet food-contact requirements. | The cited FAQ does not establish that every steam-contact surface is plastic-free. |
These comparisons reflect what the named manufacturers say in the cited pages, not product testing by this article. Confirm the current model number and ask the maker about any contact surface the listing leaves unclear.
How to Choose for Your Kitchen
Set your material boundary
Decide whether your requirement covers water only, or water plus steam and condensation, and whether silicone is acceptable. Without that decision, two shoppers can read the same maker disclosure and reach different conclusions about whether a kettle meets their needs.

- ๐๐๐ถ๐น๐ ๐๐ผ ๐๐ฎ๐๐: Durable stainless steel construction with superior heat retention (compared to Cosori 171 Glass Kettle) and Strix auto shut-off for long-term reliability.
Match capacity and controls to use
Compare the exact capacity and controls rather than assuming all glass or stainless kettles are alike. In the examples above, the GRAEF WK350 is listed at 1 L, while Mueller lists a 1.8 L model. GRAEF lists temperature settings and a 30-minute keep-warm function for the WK350. These are model specifications, not general category guarantees.
Check cleaning and safety details
Glass can make water and scale visible, while cleaning access depends on the particular opening and removable parts. Follow the exact modelโs care instructions. Check the manual or maker listing for automatic shut-off and boil-dry or overheating protection rather than assuming a feature is included.

Questions to Ask Before Buying
- What are the materials of the lid underside, spout or strainer, sensor area, and seals?
- Can steam or condensation contact plastic, including inside the lid?
- Does the answer apply to the exact model and current version I plan to buy?
- If silicone is present, where is it usedโand does that fit my definition?
- Where can I find the model manual, cleaning instructions, and replacement-part information?
FAQ
Does BPA-free mean a kettle is plastic-free?
No. BPA-free does not establish that a kettle has no plastic in its water- or steam-contact path. Check the material of each relevant surface, including the lid underside and strainer.
Does a stainless-steel interior mean the whole kettle is plastic-free?
No. A kettle can have a stainless interior and still use plastic or silicone in the lid, base, handle, sensor area, or other parts. Fellow, for example, says its current EKG models are not fully plastic-free.

Is silicone the same as plastic?
Silicone is a distinct material. Whether it meets your personal โplastic-freeโ standard is a choice to make before comparing products. Ask the maker where it appears and whether it contacts water or steam.
Which kettle has a fully plastic-free contact path?
Based on the cited manufacturer disclosures, Saki describes the Lunaโs water-contact surfaces as stainless steel and borosilicate glass, and GRAEF describes the WK300/WK350 water-contact materials as glass or stainless steel. Those are maker claims, not independent audits; verify the exact model and ask about steam contact if that is part of your standard.

Does Sakiโs reported lab test prove every Luna is free of the listed substances?
No. Saki says an outside lab tested a sample Luna for BPA, phthalates, PFAS, and heavy metals. The surfaced information does not include numerical results or full report details, and a sample test should not be generalized to every unit or to broader health claims.
Is a glass-body kettle automatically plastic-free?
No. Glass describes the body, not necessarily the lid, filter, sensor, or other contact surfaces. Mueller lists a glass body and stainless-steel filter, but its cited page does not settle every water- and steam-contact surface.
