COSORI Original Glass Electric Kettle
Borosilicate glass kettle engineered around the water path - stainless inner lid and stainless filter mean plastic never touches the water, at a budget price.
The verdict: No-contact plastic
This is one of the few mass-market kettles deliberately built so no plastic touches the water. The carafe is borosilicate glass, the spout is formed from the glass itself, the lid underside is stainless steel, and the spout filter is stainless. The heating element sits in the glass base. The handle, power switch, and 360-degree base are BPA-free plastic but are all outside the water path.

COSORI's glass electric kettles are 1.7 L borosilicate glass kettles with auto shut-off and boil-dry protection at a notably low price. Two current models share the same water path: the boil-only Electric Glass Tea Kettle (GK173, the successor to the discontinued GK172) and the Original Digital Glass Kettle (CO117-DK), which adds temperature presets and keep-warm.
Pros
- Deliberately designed so no plastic touches water - rare in this price band
- Stainless inner lid closes the usual glass-kettle plastic-lid loophole
- Borosilicate glass lets you see the water; wide mouth is easy to clean
- Inexpensive relative to steel or gooseneck alternatives
Cons
- Glass carafe is breakable and retains heat poorly
- The stainless heating disc is sealed to the glass at the bottom, so the water sits directly on that glass-to-steel seam - and Cosori doesn't disclose what the sealant is; owners have raised this in unanswered product Q&A. It's a disclosure gap, not confirmed leaching, but it's the reason strict roundups steer toward Cosori's all-steel kettles instead
- Steam condenses on the plastic lid components and can drip back into the water - not submerged plastic contact, but worth knowing
- The cheapest model (GK173) is boil-only; temperature presets need the pricier digital CO117-DK
- BPA-free plastic handle and base (outside water path, but present)
- Owned by VeSync (Levoit family); not a plastic-free-focused brand
Notes
- Capacity: 1.7 L / roughly 7 cups
- Descale periodically; glass shows mineral scale readily
- If the glass-to-steel seam concern bothers you, Cosori's all-steel kettles avoid it entirely - the double-wall stainless (CDK-SE151, our Best Budget Stainless pick) for a boiler, or the gooseneck (CO108-NK) for temperature-controlled pour-over
