national/ Panasonic n10c Rice Cooker
Lower concern, stainless/aluminum construction typical of rice cookers poses minimal PFAS risk; brand silent on the topic.
The National/Panasonic N10C uses a stainless steel inner cooking bowl and aluminum components, which are inherently PFAS-lower materials. Rice cookers rarely employ nonstick coatings or water-repellent treatments. No public PFAS claims or third-party testing data exist for this model, but the material profile is reassuring.

The full breakdown
What it's made of and why it matters
The National/Panasonic N10C uses a stainless steel inner bowl and aluminum heating plate, both common in mid-range rice cookers. Stainless steel is chemically inert under normal cooking conditions and does not leach metals into food at typical rice-cooking temperatures (around 212°F/100°C during active cooking, lower during keep-warm mode). Aluminum is more reactive but is typically anodized or clad in stainless steel in quality cookers to prevent direct contact with food; if the inner surface remains uncoated, aluminum can leach in small amounts under acidic conditions, though rice cooking does not create acidic conditions.
The brand's record and disclosure
National (Panasonic's former domestic brand name in some regions) has not published specific safety disclosures or certifications regarding heavy metals, coatings, or chemical usage in rice cooker construction based on available public records. The brand does not appear in major product safety recalls related to cookware contamination in the past 15 years. No third-party testing or certified lead/cadmium limits have been documented for this specific model, placing it in the silent-but-standard category typical of Japanese appliance manufacturers from this era.
How it compares in its category
The N10C's stainless steel and aluminum construction is typical for entry-to-mid-range rice cookers and represents a safer baseline than models with non-stick coatings (Teflon-type coating/Teflon risk at high heat) or ceramic glazes (potential lead in older or imported glazes). High-end models often add stainless steel cladding on the aluminum or use reinforced enamel coatings, but this adds cost without substantially reducing cooking safety for rice. This model avoids the durability concerns of budget cookers with thinner aluminum or unlined interiors prone to pitting.
If you buy it
Keep cooking temperatures moderate by following manufacturer water-to-rice ratios; excessive heat or prolonged keep-warm use (above 4 hours) is unnecessary and increases any theoretical aluminum leaching risk. Inspect the inner bowl annually for visible corrosion, pitting, or discoloration; stainless steel is durable but should be replaced if the surface becomes rough or discolored. Do not use abrasive scrubbers on the interior; hand wash with soft sponges and mild detergent, or use the gentle dishwasher cycle if the bowl is removable. Replace the cooker if the heating element shows signs of failure or the bowl develops cracks, as continued use risks both performance degradation and potential uneven heating.
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 from heating plate
Direct aluminum contact with rice is unlikely if stainless steel is properly anodized or clad, but minor leaching under normal cooking conditions (neutral pH, moderate heat) is theoretically possible though not documented in recalls. Risk is minimal for rice (non-acidic, short cooking time) but would increase if cooker were misused for acidic foods like tomato soup.
Coating degradation (enamel or non-stick if present)
Available product descriptions and user reports do not indicate that this model uses Teflon-type coating non-stick or enamel coatings on the inner bowl; the stainless steel is the primary cooking surface, so chipping or fume risk is not a documented concern.
Heavy metals in stainless steel (nickel, chromium)
Food-grade stainless steel (typically 304 or 316 grade) used in cookware is formulated to minimize leaching of nickel and chromium under normal cooking conditions. No recalls or test reports indicate elevated heavy metal migration from this model into rice or water.
Bacterial growth in keep-warm reservoir
Extended keep-warm cycles (beyond 4-6 hours) at temperatures below 140°F can allow bacterial proliferation; this is a usage issue rather than a material defect but is common to all rice cookers. Follow manufacturer guidance on keep-warm duration to minimize food safety risk.
Off-gassing or odor from new appliance
Stainless steel and aluminum do not off-gas significantly; any plastic components (cord, casing) may emit minor VOCs on first use but dissipate within hours to days. No specific reports of odor complaints for this model.
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.
