Pyrex No-Leak Glass · Food Storage Containers
Pyrex Simply Store Meal Prep Glass Storage Set
Lower PFAS concern, borosilicate glass itself is not a PFAS vector, but plastic lid coatings warrant basic caution.
Pyrex Simply Store uses borosilicate glass containers, a material with no established PFAS risk. The plastic lids are the potential concern point; Pyrex makes no PFAS disclosures.

Why this grade
Category baseline
food packaging 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 containers themselves are borosilicate glass, a thermally stable material that resists thermal shock and does not leach chemicals into food under normal use. The lids are polypropylene (PP, plastic #5), which has a higher melting point (160°C/320°F) than most common food-contact plastics and is considered low-leaching when kept below its thermal limit. The combination of inert glass and PP is among the safer options in meal prep storage; glass provides a passive barrier that does not degrade over time.
The brand's record and disclosure
Pyrex (owned by Instant Brands) does not publish formal PFAS or chemical-use transparency statements specific to this line. The brand has not been subject to major product recalls related to leaching or coating degradation in recent years, though Pyrex has faced historical litigation over thermal shock failures in earlier bakeware lines (unrelated to storage containers). No independent testing or third-party certifications (e.g., BPA-free declarations) are prominently marketed for this product line, which reflects a minimalist disclosure posture rather than active reassurance.
How it compares in its category
Glass storage containers are among the safest category options because the material itself is chemically inert and does not leach under any food-contact scenario. Compared to plastic-only containers (which may contain BPA, BPS, or phthalates) or ceramics with unknown glaze composition, this Pyrex set eliminates leaching risk from the container walls. The polypropylene lids are standard for glass meal prep containers; competing brands (Rubbermaid Brilliance, OXO, Anchor Hocking) use identical or similar materials with no documented advantage.
If you buy it
Do not microwave the lids or expose them to temperatures above 160°C (320°F); transfer food to a bowl if reheating is needed. Hand-wash lids rather than using the dishwasher's hot cycle to extend their lifespan and prevent wear. Replace lids if they become cloudy, cracked, or develop odors, as these signs indicate material degradation. The glass itself is durable and dishwasher-safe indefinitely; focus maintenance on the plastic components.
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 or bisphenol analogs in polypropylene lid coatings
Polypropylene itself does not require BPA to achieve function, and Pyrex has not disclosed BPA use in this line. No independent testing or recalls suggest contamination, but the brand's silence on the topic leaves room for routine caution during high-temperature use.
Phthalates in plastic lids
Polypropylene is rarely plasticized with phthalates because its stiffness does not require them. No evidence links this product to phthalate content, but lid flexibility or any unusual odor would warrant replacement.
Microplastics from lid degradation
Repeated heating, dishwasher cycling, and UV exposure can cause microscopic plastic wear in polypropylene lids over years of use. This is a general risk for all plastic-lid food storage and is not unique to Pyrex, but conscious replacement of visibly worn lids mitigates it.
Lead or cadmium in borosilicate glass
Borosilicate is inherently low in lead and cadmium compared to soda-lime glass or ceramics. No testing or recalls suggest contamination in this product line. The material's chemistry makes intentional addition unlikely.
Coating degradation or delamination over time
Any non-stick or decorative coatings on the glass surface (if present in some versions) could degrade with prolonged use, though borosilicate glass storage containers typically have minimal additional coatings. Check for visual wear and discard containers with visible peeling or discoloration.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 88% 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.
