Oster 6-Cup Electric Rice Cooker
Lower PFAS concern; typical appliance with no Teflon-family coating, but Oster offers no transparency.
Oster's 6-cup rice cooker uses a stainless steel inner cooking pot and plastic housing, no nonstick Teflon-family coating is evident from standard product specs. The brand does not disclose PFAS presence or absence.

Why this grade
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This model uses a stainless steel inner cooking pot, which is chemically inert and does not leach metals into food under normal use. The exterior housing is polypropylene plastic, a common food-contact material that is stable at the temperatures generated by a rice cooker. No Teflon-family coating non-stick coatings (like Teflon-type coating/Teflon) are involved, eliminating the fume-release risk associated with overheated non-stick cookware.
The brand's record and disclosure
Oster is a mature appliance manufacturer owned by Sunbeam Products and has not faced major food-safety recalls specific to rice cooker construction or materials. The brand does not publish detailed material sourcing or PFAS avoidance statements, reflecting typical silence among budget-tier small-appliance makers. No established controversies regarding heavy metals, coatings, or leachables in Oster rice cookers appear in public records.
How it compares in its category
Stainless steel inner pots are standard across budget and mid-range rice cookers and are considered safer than non-stick alternatives. This 6-cup capacity is typical for household use and does not require any exotic or high-risk materials. Oster's offering sits in the conventional middle ground, with no premium claims (and no premium safety transparency) compared to other sub-$50 rice cookers from brands like Hamilton Beach or Black+Decker.
If you buy it
Stainless steel pots are durable and do not require special care beyond normal washing; avoid abrasive scrubbers that may scratch the surface cosmetically but will not compromise safety. Do not submerge the heating base or electrical components. Empty and dry the pot after each use to prevent mineral buildup from hard water, which can cloud the steel but poses no health risk. Replace the plastic exterior housing or cord if cracked or damaged to prevent electrical hazards, though the pot itself is long-lived.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Aluminum leaching
No aluminum is used in the inner cooking pot or food-contact surfaces. The stainless steel pot is the active cooking vessel.
Teflon-type coating/Teflon fume emission
This model uses stainless steel, not non-stick Teflon-family coating coatings, so the risk of toxic fume release from overheating is not present.
Polypropylene plastic leaching (exterior housing)
The plastic exterior can release small amounts of polypropylene oligomers or residual additives if heated well above 200 degrees Celsius, but normal rice cooker operation (steam environment, ~100 degrees Celsius) does not reach this threshold. No BPA is typically used in polypropylene molding, though additive composition is not disclosed by Oster.
Stainless steel chromium or nickel leaching
Food-grade stainless steel (typically 304 or 316 grade) is corrosion-resistant under normal use, but acidic or high-salt foods may cause trace nickel or chromium release over decades of use. This is not unique to Oster and is consistent with the material class; risk is minimal for typical rice and water cooking.
Electrical safety (housing degradation)
Plastic housings can become brittle or crack with age and repeated heat cycles. Inspect the exterior and cord annually for damage; cracks that expose wiring pose electrocution or burn risk, particularly if used near water.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
