National/ Panasonic N5C Rice Cooker
Lower concern for PFAS, stainless steel inner pot typical of rice cookers, but verify exterior materials with manufacturer.
The National/Panasonic N5C is a traditional electric rice cooker with a stainless steel inner cooking pot, which presents lower PFAS risk compared to nonstick cookware. The brand makes no PFAS claims either way. Exterior plastics and seals are not typically disclosed; contact Panasonic if you need material specifics for peace of mind.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
The N5C uses a stainless steel inner pot, which is chemically inert and does not leach metals like aluminum or cadmium into rice or water during normal cooking. The exterior housing is plastic and glass, materials that typically do not contact food directly but can off-gas volatile organic compounds (VOCs) if exposed to sustained high heat above their design limits. Stainless steel pots in rice cookers are considered the safest pot material for this appliance class because they resist corrosion and degradation over time, even with repeated wet-heat cycles.
The brand's record and disclosure
National (Panasonic's Japanese consumer brand) has not publicly disclosed detailed chemical composition or toxicology testing data for the N5C housing materials. The company maintains general safety certifications typical of kitchen appliances in major markets but has not published responses to PFAS or other contaminant concerns. No major product recalls related to material safety have been documented for this model in public databases.
How it compares in its category
Stainless steel inner pots are standard in mid-range and premium rice cookers; the N5C is typical rather than exceptional. Many budget models use non-stick coatings or aluminum, which carry leaching and degradation risks absent here. The plastic-and-glass exterior is common across the category; competitors typically use similar materials without reported hazard complaints.
If you buy it
Avoid leaving the cooker running or on 'warm' mode continuously for more than a few hours, as sustained low heat can increase plastic off-gassing. Do not submerge the exterior housing in water or expose it to direct flame. Inspect the stainless steel inner pot annually for pitting or discoloration; replace if visible corrosion develops (rare but possible after 5+ years of heavy use). Clean with mild soap and water; avoid abrasive scrubbing that may degrade any protective oxide layer on the steel.
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.”
Plastic housing off-gassing (VOCs)
The exterior plastic casing may release low levels of volatile organic compounds when heated repeatedly or exposed to warm environments. Risk is minimal during normal use but increases if the cooker is run continuously for 8+ hours or left in direct sunlight.
Stainless steel inner pot corrosion and leaching
Stainless steel is highly resistant to leaching under normal rice-cooking conditions. No documented cases of nickel, chromium, or other steel components entering food have been reported for this product category, though extremely prolonged exposure to acidic or salt-rich liquids could theoretically initiate slow surface degradation.
Glass or plastic lid degradation
Repeated thermal stress (heating and cooling cycles) can cause micro-fracturing in glass lids or softening in plastic components. Inspect the lid for cloudiness, cracks, or warping before each use; replace if compromised to prevent contamination from loose particles.
Bacterial growth in condensation traps or vents
Rice cookers accumulate steam condensation in internal vents and water collection areas. If not cleaned regularly, stagnant water can support mold or bacterial growth. Wipe dry interior surfaces and vents weekly if the cooker is used daily.
Thermal burns or electrical hazard from continued wear
This is a mechanical and electrical durability concern rather than material toxicity. Power cords, heating elements, and switches can degrade over time; inspect the cord annually for cracks or fraying and do not use if damage is visible.
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.
