Cuckoo CR-1020F 10-Cup Micom Rice Cooker and Warmer
Lower PFAS concern for the inner cooking vessel; no disclosure on exterior coating or seals.
The Cuckoo CR-1020F uses a stainless steel inner pot for cooking, which poses lower PFAS risk than nonstick surfaces. The brand makes no public claims about PFAS in materials or finishes.

The full breakdown
What it's made of and why it matters
The Cuckoo CR-1020F uses a stainless steel inner cooking pot, which is chemically inert and does not leach metals or off-gas during normal rice cooking at standard temperatures (under 212°F during boiling, slightly higher during pressure if applicable). The exterior housing and lid are plastic and silicone components that experience lower direct heat exposure, reducing volatilization risk, though the seals and gaskets (common sources of PFAS in kitchen appliances) are not publicly disclosed by the manufacturer. No ceramic or enamel coating is present on the cooking surface, eliminating concerns about lead or cadmium in glazes.
The brand's record and disclosure
Cuckoo is a South Korean appliance manufacturer with a primary focus on rice cookers and pressure cookers, but has published minimal transparency on chemical composition, including PFAS use in non-stick coatings or seals. The brand does not advertise certifications such as NSF, FDA pre-market notification, or third-party testing results for leaching or off-gassing. No major safety recalls specifically targeting chemical hazards have been widely documented for this model in US regulatory databases, though the absence of disclosure makes independent verification difficult.
How it compares in its category
Rice cookers with stainless steel pots are standard across mid-range brands (Zojirushi, Instant Pot, Tiger); the CR-1020F is competitive in this regard. Unlike non-stick rice cookers with Teflon-type coating-coated surfaces, stainless steel eliminates fume risk if the pot is accidentally heated empty or overheated. However, Cuckoo lags behind Japanese competitors (Zojirushi, Tiger) in published material safety disclosures and third-party testing transparency, making it harder to assess exterior component safety relative to alternatives.
If you buy it
Inspect the rubber gasket and silicone seals before first use; replace them every 1-2 years or if they show discoloration, hardening, or persistent odor, as these are the most likely source of leachable chemicals or PFAS. Do not operate the cooker with an empty pot or at temperatures above the appliance's rated maximum, and ensure ventilation during the first few uses to allow any residual manufacturing volatiles to dissipate. Avoid storing acidic foods (vinegar-based dishes) in the cooker for extended periods, as stainless steel can be slightly reactive over time. Clean the exterior plastic housing with mild soap and avoid abrasive solvents.
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.”
Silicone/rubber seals and gasket leachables
Cuckoo does not disclose the composition of the lid gasket or steam vent seals. Silicone and rubber components can leach oligomers or residual monomers into hot food or steam, though risk is low during normal rice cooking. Replacement gaskets are available aftermarket but should be inspected annually.
Stainless steel interior pot nickel leaching
Food-grade stainless steel (typically 18/8 or 18/10) used in rice cookers leaches negligible nickel under normal acidic pH and temperature conditions. No documented incidents or test data showing elevated nickel migration from Cuckoo pots in published sources.
Plastic housing off-gassing (volatile organic compounds)
The exterior plastic components may release volatile organic compounds (VOCs) such as styrene or other monomers during manufacture and initial heating cycles. This risk is typically low for rice cookers since the plastic is not directly contacted by food and operates at moderate ambient temperatures, but sensitive individuals may detect odors on first use.
Thermal damage to plastic components under misuse
Inadequate disclosure on non-stick or anti-microbial coatings
Cuckoo does not publicly disclose whether the inner pot has any coating (e.g., food-safe non-stick or anti-bacterial treatment) beyond the base stainless steel. If a coating is present and not documented, composition and long-term durability remain uncertain. Based on product imaging, the pot appears uncoated, but manufacturer clarification is absent.
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.
