All-glass brewing with no plastic parts touching hot water. Paper filters are chlorine-free. Unlike plastic drip machines that leach BPA and microplastics at brewing temperatures. See our plastic-free coffee maker guide.

What this replaces is a drip machine, where near-boiling water sits in a plastic reservoir and runs through plastic tubing before it reaches your cup, and single-serve pod machines, where hot water is forced through a plastic pod. If you want zero plastic anywhere on the object, a stainless steel press or a glass pour-over with a steel dripper gets you there.
Straight answer: we're a research team, not a testing lab. Here's exactly what our rating is based on — and what it isn't — so you can weigh it honestly.
Anything that adds a known microplastic, PFAS, or off-gassing source — a non-stick coating, a plastic surface against food or skin, vinyl/PVC — is downgraded or cut. We only list what clears that bar.

Vacuum-insulated 18/8 stainless tumbler for coffee, so a hot drink is never held against plastic. The café cap is plastic; the drink sits in steel.
Loose-leaf eliminates plastic tea bags entirely. A 2019 McGill study found a single plastic tea bag releases 11.6 billion microplastic particles per cup. Learn more in our plastic tea bag article.
