Caraway 17-Piece Food Storage Set - Navy
Lower-concern choice; glass + verified PFAS-free claim reduce risk, though plastic lids warrant scrutiny.
Caraway's 17-piece set uses borosilicate glass (inherently PFAS-free) with BPA-free plastic lids. The brand explicitly markets it as PFAS-free and holds MADE SAFE certification.
Brand says: “Caraway explicitly states their food storage containers are PFAS-free and made from glass.”

Why this grade
Category baseline
food packaging is a category where PFAS exposure is more common.
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
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
This set pairs borosilicate glass containers with BPA-free plastic lids. Borosilicate glass is chemically inert and does not leach into food at normal temperatures, making it the safest common food storage material. The plastic lids are the variable: BPA-free designation removes one known endocrine disruptor, but other plasticizers or degradation products in the lid material remain possible over years of use, particularly if exposed to heat, dishwashers, or oils.
The brand's record and disclosure
Caraway publicly markets this set as BPA-free and has made explicit PFAS-free claims across its cookware and storage lines. The brand has voluntarily published material sourcing transparency and responded to consumer inquiries about chemical content. No major recalls or safety violations are on record for this storage line. Their stated commitment to non-toxic materials aligns with third-party reviews noting the absence of chemical odor or off-gassing typical of lower-cost plastic-lid containers.
How it compares in its category
Glass containers with plastic lids occupy the middle-to-premium segment of food storage. They outperform single-use plastic or polycarbonate alternatives (which may contain BPA or bisphenols) and match the safety of stainless steel containers, but cost more. Caraway's borosilicate-grade glass is thicker and more durable than budget glass sets, reducing breakage and the need for frequent replacement, which itself reduces cumulative hazard exposure.
If you buy it
Store at room temperature or refrigerated; avoid prolonged microwave heating with lids sealed, as trapped steam and heat can stress plastic seals. Hand wash lids if possible rather than dishwasher to extend plastic lifespan and reduce thermal stress. Replace lids if they crack, become discolored, or develop persistent odors, as these signal polymer degradation. Glass containers themselves are nearly indefinite in lifespan; lids typically warrant replacement every 3 to 5 years depending on frequency of use.
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.”
BPA and other bisphenols in plastic lids
Caraway explicitly labels these lids BPA-free. No public reports of BPA detection in independent testing of this product line. However, BPA-free does not guarantee absence of other endocrine-active plasticizers; the full list of lid polymers is not fully disclosed.
Phthalates in plastic lid material
Phthalates are sometimes used in flexible plastics to improve durability. Caraway's lid material composition is not exhaustively detailed in public disclosures, so residual phthalates cannot be ruled out, though no specific reports of contamination exist for this product.
Microplastics from lid degradation
Over years of use, plastic lids may shed microparticles, especially if frequently heated, bent, or damaged. Boiling or high-heat storage inside sealed containers increases this risk. Regular lid replacement mitigates this.
Lead or cadmium in glass
Borosilicate glass is a standard food-grade material and does not typically contain lead or cadmium. No recalls or safety alerts have been issued for Caraway glass containers on this basis.
Leaching from plastic lids at room temperature or refrigeration
Plastic lids may slowly leach residual monomers or plasticizers into food over extended contact, particularly fatty or acidic foods. The risk is lower at cool temperatures but non-zero. Rotating lids and avoiding long-term contact with oils reduces exposure.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
