Electric kettles without plastic: which parts touch the water, by the maker's own description
Plenty of kettle listings promise that no plastic touches the water. What a maker writes in its own documents can be more specific than that, or less. We read the product pages, manuals and help articles from Fellow, Cosori and OXO for four kettles, plus the California chemical disclosures where they exist, and wrote down what each one says about the parts the water touches. Where a maker says nothing, the table says so.
Fellow gives the fullest description: a 304 stainless steel interior, a stainless steel underside to the lid, and silicone around the temperature probe and in the lid gasket. Fellow also says its kettles are not fully plastic-free. Cosori says the SE152 has a stainless steel interior with a plastic-free inner lid and filter. For the two glass kettles, the makers name the glass and the steel parts but not the lid.
What touches the water, kettle by kettle
| Kettle | Body | Lid underside | Filter or infuser | Seals | Maker on plastic |
|---|---|---|---|---|---|
| Fellow Stagg EKG Pro | 304 stainless steel | Stainless steel | None named | Silicone ring at the probe, silicone lid gasket | Not fully plastic-free |
| Cosori SE152 | 304 food-grade stainless steel | Plastic-free inner lid | Plastic-free filter | Not named | Plastic-free interior |
| OXO Brew Cordless Glass | BPA-free borosilicate glass and stainless steel | Not stated | Perforated stainless steel | Not named | No statement |
| Cosori glass with infuser (CGK-G119TI) | Glass, 304 stainless steel rim | Not described | 304 stainless steel infuser | Not named | No statement on this page |
Both Cosori rows come from the image descriptions on Cosori's product pages, not from a written materials list or manual. We count them as the maker's statement; a spec sheet would be stronger evidence.
What "no plastic contact" usually leaves out
Water reaches more than the body. It also meets the underside of the lid, the gasket that seals it, the ring around the temperature probe, the filter in the spout and, on some kettles, a water-level window. The handle and the base stay dry, so plastic there is a separate question.
Of the three makers, only Fellow goes through those parts one by one, and only Fellow says plainly that its kettles still contain plastic: in parts of the lid, the base and the handle. It also answers the PFAS question directly. Fellow says all external kettle parts, including those that touch water, are PFAS-free, and that the only PFAS is in components of the control board inside the base.
Get it if You want the clearest maker description of what the water touches, and you brew pour-over coffee or tea.
Skip it if You want a kettle with no plastic and no silicone anywhere: Fellow says this is not one.
- Fellow names every material the water touches: 304 stainless steel and a silicone ring around the temperature probe
- The underside of the lid is stainless steel, according to Fellow
- Fellow says the parts that touch water are PFAS-free; PFAS remains only in control-board components inside the base
- The plastic Fellow lists is in parts of the lid, the base and the handle
- Fellow says its EKG kettles are not fully plastic-free
- Silicone in two places: the probe ring and the lid gasket

Get it if You brew loose tea and want glass and steel where the maker describes the parts.
Skip it if You need every part that touches the water named before you buy.
- Glass body with a 304 stainless steel rim, according to Cosori
- Removable 304 stainless steel tea infuser (maker)
- Six temperature presets and a 60-minute keep-warm (maker)
- Cosori's page does not describe the underside of the lid or the seals
- Cosori's California disclosure groups this kettle with other models, so its chemical list cannot be read for this model alone
California chemical disclosures
Since 2023, California law has required cookware makers to post on their website any chemicals from the state's designated list that they intentionally add to a handle or to a surface that touches food or drink (Health and Safety Code 109012). Kettles show up in these disclosures. The lists name chemicals; they are not a safety rating.
OXO lists the spout filter of the Cordless Glass Electric Kettle with chromium, iron, manganese and nickel, the elements of stainless steel. Cosori's disclosure has a kettle section that groups several models under one list of chemicals, so it cannot be read model by model. No kettle in that section lists PTFE, which Cosori does list for some of its other appliances.
If you also filter your water
Certification for what is in the water works per contaminant and belongs to the filter. For microplastics, see which filters have a listing that names them. If you would rather have filtered hot water from one machine, the Waterdrop M6H on our countertop water filters page dispenses it. We have not checked the materials of its hot water path, so it is not in the table above.
