(2 pack) Rice Robot Personal Rice Cooker, PFAS-free, Nonstick. 1 Quart Capacity (4 Cups), with Stainless Steel Steamer Tray, Measuring Cups, Recipe
Explicit PFAS-free claim is a strong signal, but lack of third-party verification or coating detail leaves moderate uncertainty.
Aigostar explicitly markets this rice cooker as "PFAS-free" and includes stainless steel components, which lowers concern. However, the nonstick coating type is not specified, and there is no third-party certification (MADE SAFE, EWG Verified) to independently confirm the claim.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This rice cooker uses an unspecified nonstick coating on the inner cooking bowl, paired with a stainless steel steamer tray. Aigostar's explicit PFAS-free claim suggests the coating is likely ceramic, silicone-based, or a newer hydrocarbon polymer, but the manufacturer has not disclosed the exact formulation publicly. Stainless steel is chemically stable under normal rice-cooking temperatures (around 212°F) and poses no known leaching risk. The coating's durability and safety depend heavily on its specific chemistry and how well it is maintained.
The brand's record and disclosure
Aigostar markets this product with a direct PFAS-free claim, signaling awareness of consumer concern around nonstick coatings. However, the brand does not appear to have published third-party test results, Safety Data Sheets for the coating material, or independent certifications (e.g., from NSF or similar bodies) confirming the absence of PFAS. No major recalls or safety controversies for this model are documented in public records. The lack of granular material transparency is typical of budget-range small appliances but leaves room for uncertainty.
How it compares in its category
Personal-size rice cookers with nonstick interiors dominate the under-$50 segment. This Aigostar model's PFAS-free claim puts it ahead of many competitors that remain silent on coating chemistry or continue using Teflon-type coating (Teflon). Most stainless steel alternatives (like Zojirushi or Tiger) cost 2-3x more but offer proven track records and detailed material specs. Mid-range options with ceramic or anodized aluminum coatings also exist but are less common at this price point and capacity.
If you buy it
Keep the rice cooker on its low heat setting (avoid high-temperature searing or browning modes) to minimize stress on the coating. Hand-wash the bowl; dishwasher use can accelerate wear. Inspect the nonstick surface every 6-12 months for peeling, pitting, or discoloration; if the coating visibly degrades, retire the unit. Avoid using metal utensils inside the bowl, and do not exceed the maximum fill line. Store in a dry location to prevent moisture-driven corrosion of the stainless tray.
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.”
Nonstick coating degradation and fume risk (non-PFAS)
Unspecified nonstick chemistry increases uncertainty. If the coating is ceramic or hydrocarbon-based, fume risk at normal cooking temperatures is low; however, any coating that flakes or peels over time poses ingestion and potential off-gassing concerns. No recalls or incident reports for this model are documented.
Aluminum leaching (from heating vessel)
The cooking bowl material is not explicitly stated; if aluminum rather than stainless steel, mild leaching under acidic conditions (e.g., cooking rice with acidic ingredients) is theoretically possible but typically negligible in short, neutral rice-cooking cycles. Stainless steel steamer tray poses no leaching risk.
Electrical safety and thermal injury
No documented electrical failures or burn hazards for this 1-quart model. Standard rice cooker safety features (automatic shutoff) are expected but not confirmed in available product documentation. Risk is typical for the category.
Lead or cadmium in glaze or coating pigments
No recalls or testing has flagged heavy metals in Aigostar nonstick rice cookers. Stainless steel and modern nonstick coatings do not typically contain lead or cadmium, but lack of third-party certification leaves this unverified.
Microplastics from coating wear (if polymer-based nonstick)
If the PFAS-free coating is a hydrocarbon polymer or silicone, minor particle shedding from mechanical wear is theoretically possible over years of use, though no evidence of harm at typical exposure levels exists. Ceramic and anodized coatings present lower risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
