Compare Coffee Machine
Which scores higher on safety? R3 breaks it down.
The most important dimensions, side by side.
The 60-oz removable reservoir is confirmed BPA-free, which is reassuring. However, Ninja doesn't disclose the specific plastic type used, so we can't fully evaluate what your water is in contact with before brewing.
The reservoir is confirmed BPA-free, but OXO doesn't disclose the specific plastic type. Without knowing the exact polymer, we can't fully verify whether replacement chemicals like BPS or BPF are present.
Ninja explicitly declares the reservoir and carafe components BPA-free — a clear commitment to reducing chemical exposure in your daily brew.
OXO explicitly confirms all water-contact and coffee-contact components are BPA-free — a meaningful safety commitment for daily use.
This machine carries UL certification, meaning an independent lab has verified it meets rigorous electrical safety standards for fire, shock, and overheating protection.
OXO is an established brand sold through every major US retailer, and the instruction manual includes standard electrical safety warnings consistent with certified products. We're confident this machine meets safety standards, though OXO doesn't prominently display the certification mark in their online materials.
At 200°F, this brewer hits the sweet spot for coffee extraction — your grounds release full flavor without bitterness, producing a rich, well-balanced cup every time.
OXO's BetterBrew technology delivers water in the optimal 197-205°F range for full flavor extraction. This is an SCA-certified brewer — it meets the same brewing standards as machines costing twice as much.
The glass carafe sits on an adjustable warming plate, which keeps coffee hot but continuously degrades its flavor. The adjustable temperature helps a bit, but coffee left on the plate for over 30 minutes won't taste as fresh.
The double-wall vacuum-insulated stainless carafe keeps coffee hot for hours without a warming plate — your coffee won't develop that overcooked taste that glass-on-hotplate models produce.
The glass carafe and reservoir are both dishwasher-safe, making daily cleanup genuinely effortless — no hand-scrubbing required.
The brew basket and Rainmaker showerhead are dishwasher safe, but the thermal carafe itself needs hand-washing — standard for vacuum-insulated carafes.
The 60-oz reservoir detaches completely so you can carry it to the sink for filling — no awkward pouring from a pitcher or positioning the machine near the faucet.
The water tank is built into the back of the machine — you'll need to bring a pitcher or cup to fill it rather than taking it to the sink.
Set the 24-hour delay brew the night before and wake up to a fresh pot — it's the kind of feature that quickly becomes indispensable in a busy morning routine.
There's no timer or delay brew — you press the button when you're ready. OXO designed this as a simple, one-button brewer without scheduling features.
The permanent screen filter means no paper filter runs — just rinse and reuse. You can also swap in paper filters if you prefer a cleaner cup.
Uses basket-style paper filters — you'll need to keep them stocked. Third-party reusable filters are compatible if you prefer to skip the paper.
At $90, the CE251 offers exceptional convenience features — removable tank, permanent filter, delay brew — at a very competitive price point for a 12-cup brewer.
At $199.99 this is the most affordable SCA-certified thermal carafe brewer on the market — you're getting brew quality that rivals $350 machines. Price is recorded for context but does not affect the R3 score.

You're looking for a feature-packed 12-cup brewer under $90 that includes a permanent filter

You want SCA-certified brew quality with a thermal carafe at the lowest price available in this segment
You brew both full pots and single cups and want a machine that handles both without accessories
You prefer a simple one-button operation without complicated menus or programming
You're comfortable with the trade-off of fewer convenience features for better brew quality per dollar
The main thing to know
The glass carafe on its warming plate continuously degrades your coffee's flavor — if you don't drink the full pot within 30 minutes, the taste noticeably declines compared to thermal carafe models.
Every usability feature is stripped away — no programmable timer, no removable reservoir, no dishwasher-safe carafe, no permanent filter. This is a machine for coffee purists who don't mind a hands-on routine.
Skip this if you...
You need full material transparency about what type of plastic contacts your hot water before brewing
You want your coffee to stay fresh for hours without flavor degradation — a thermal carafe model would serve you better
You want full material transparency about what type of plastic contacts your hot water before brewing
You want to wake up to fresh coffee — there is no programmable timer or delay brew feature on this machine
Full material safety transparency is important to you — the reservoir polymer is not disclosed despite the strong BPA-free commitment
You want a removable water tank and dishwasher-safe carafe for minimal daily maintenance effort
Neither of these quite what you're looking for?
