Cosori CEK-S153 vs Fellow Stagg EKG Pro vs Breville Soft Top Pure

Head-to-head materials table for three popular electric kettles: Cosori's all-metal-interior claim, Fellow's disclosed silicone + polypropylene, and Breville's BPA-free plastic water windows.

How to read verdicts: Pass = primary food/water contact is metal, glass, or disclosed silicone-only seals with no plastic. Partial = usable if you skip a coated accessory, or plastic remains on lids/seals. Fail = plastic or fluoropolymer/nonstick cooking surface in the normal use path.

This is a materials comparison, not a pour-quality ranking. Cosori markets a 304 stainless water path with no plastic contacting water. Fellow publishes a detailed BOM: 304 stainless interior plus silicone probe ring, silicone lid gasket, and BPA-free polypropylene on lid/handle/base. Breville Soft Top Pure uses a brushed stainless body with dual BPA-free plastic water windows in the water path — a mainstream fail for plastic-free rules even though the windows are BPA-free.

Partial

Fellow · Model Stagg EKG Pro

Why: 304 stainless interior, but Fellow's own help article states a compression-molded silicone ring around the temperature probe and a silicone lid gasket; lid/base/handle include BPA-free polypropylene. Excellent pour-over kettle; not fully polymer-free in the water/steam path.

Fail

Breville · Model BKE700BSSUSC

Why: Brushed stainless body, but dual BPA-free plastic water windows contact the water. Breville discloses food-contact plastics tested for BPA; that still fails a no-plastic-touching-water rule.
