Pyrex Totalseal · Food Storage Containers
Snapware Total Solution Pyrex 4-piece Glass Storage Set with Plastic Lids
Lower PFAS concern for glass portion; plastic lids lack transparency, skip if PFAS-sensitive.
The borosilicate glass storage containers present lower PFAS risk inherently. However, the plastic lids' material composition (polypropylene, polycarbonate, or other) is not disclosed, and Pyrex/Snapware makes no public PFAS statements.

Why this grade
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
The containers are borosilicate glass, which is chemically inert and does not leach into food under normal use. The plastic lids are composition-unspecified, a significant gap since food-contact plastics can migrate compounds like BPA or phthalates into stored food, especially if heated or aged. Borosilicate is superior to soda-lime glass for thermal shock resistance and durability, reducing coating failure risk.
The brand's record and disclosure
Pyrex (owned by Snapware/Groupe SEB) has not publicly committed to PFAS-free manufacturing for plastic components, and the lids lack material transparency on this product. The brand has no known major food-contact safety recalls in recent years, but the silent stance on lid composition reflects insufficient consumer information. Pyrex maintains general food-safety compliance but does not lead on transparency compared to competitors like Rubbermaid or Oxo.
How it compares in its category
Borosilicate glass containers rank among the safest for storage; however, many competitors (Pyrex itself, Rubbermaid Brilliance, Oxo) now offer lids with stated BPA-free or certified-safe materials. This Snapware set does not specify lid material, placing it below branded alternatives that disclose polypropylene or certified lids. Glass-only alternatives (e.g., glass bowls with glass lids) eliminate plastic migration risk entirely but are less common and pricier.
If you buy it
Do not microwave or dishwash the lids unless manufacturer guidance confirms safety; hand-wash lids in cool water to minimize plastic leaching into hot food residue. Replace lids every 2-3 years or sooner if they show cloudiness, cracks, or warping, as degraded plastic poses higher migration risk. Store acidic foods (tomatoes, citrus) in the glass containers for minimal contact with plastic. Keep lids away from high heat and do not use for long-term storage of fatty or oily foods, which accelerate plastic breakdown.
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 phthalates in plastic lids
Lid composition is unspecified; standard food-contact plastics may contain BPA or phthalates. Risk increases with heat, age, or storage of fatty/acidic foods. Migration into food is possible but generally low under cool, brief storage.
Plastic lid degradation and microplastic shedding
Unspecified plastic lids degrade over time, especially with dishwasher use or thermal cycling. Cloudiness and brittleness are visible signs; degradation may release microparticles into stored food.
Borosilicate glass thermal shock
Borosilicate glass is engineered to resist thermal shock better than soda-lime glass. No safety concerns are on record for normal use (oven, freezer, dishwasher); risk is low.
Lid seal failure and food contamination
Plastic lids may not maintain an airtight seal over time, leading to food spoilage rather than chemical hazard. Non-food contamination (dust, mold) is a hygiene concern if seals fail.
Heavy metals in glazes (glass containers)
Borosilicate glass does not use ceramic glazes or enamels, so lead and cadmium contamination is not a concern for the container body. Pyrex has not faced recalls for leaching from glass in recent years.
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.
