Anchor Hocking Snugfit Glass Storage 10 Count
Lower-concern choice, glass containers carry minimal PFAS risk, though lid materials deserve scrutiny.
Anchor Hocking's glass food storage containers are made from borosilicate glass, a material with no inherent PFAS concern. The brand makes no PFAS claims and provides no third-party verification.

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
Anchor Hocking Snugfit containers are constructed from borosilicate glass, a high-silica formulation designed for thermal shock resistance and chemical inertness. Borosilicate glass does not leach BPA, phthalates, or other plasticizers because it contains no organic polymers. The metal lids (typically stainless steel or aluminum with silicone or plastic gaskets) are the only components where minor leaching is theoretically possible, but metal-to-food contact through sealed lids under normal storage is minimal and poses negligible risk.
The brand's record and disclosure
Anchor Hocking is a long-established US glassware manufacturer with no major recalls specifically tied to chemical leaching or hazardous coatings in recent decades. The company maintains silent stance on PFAS in manufacturing processes and product disclosure, which is typical for glass container makers but does not indicate a problem. No peer-reviewed studies or FDA enforcement actions have identified safety violations in their standard glass food storage lines.
How it compares in its category
Glass storage containers rank among the safest options in the food storage category, well ahead of plastic alternatives that carry BPA or phthalate leaching risks. Compared to ceramic or stainless steel containers, borosilicate glass offers superior chemical inertness and transparency without glaze concerns. Anchor Hocking's product is competitively priced and functionally equivalent to Pyrex or OXO glass storage, with no material advantage or disadvantage.
If you buy it
Borosilicate glass is safe for oven, microwave, and freezer use within typical temperature ranges (most products rated to 400-500°F); verify your specific product label. Inspect metal lids and silicone gaskets annually for corrosion, cracking, or degradation; replace gaskets if they become brittle or discolored. Avoid sudden temperature swings (hot glass to cold water) which can cause thermal shock and breakage. Hand washing is gentler on gaskets than dishwashers; air-dry upright to prevent trapped moisture.
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.”
Metal lid corrosion and gasket degradation
Silicone or rubber gaskets in metal lids can harden, crack, or discolor over 3-5 years of repeated use, especially in humid storage. Corroded metal lids may shed microscopic particles; replacement gaskets are widely available and inexpensive.
Borosilicate glass breakage from thermal shock
Rapid temperature changes (hot oven to cold countertop, or freezer to microwave) can cause fracture. This is a mechanical hazard, not a chemical one, but glass shards are a known risk for any glassware product.
BPA/phthalates in gasket materials
Anchor Hocking does not publish detailed gasket composition. Most modern silicone gaskets are BPA-free, but elderly or replacement gaskets from unknown sources could theoretically contain these compounds. Contact manufacturer for gasket material specifications if concerned.
Lead or cadmium in glass or metal
Borosilicate glass manufactured in the US is not formulated with lead or cadmium. Stainless steel lids do not typically leach heavy metals. No recalls or reports exist for Anchor Hocking containers on this issue.
Microplastics or off-gassing
Glass and stainless steel do not emit volatile organic compounds or degrade into microplastics under normal storage or heating. This hazard class is irrelevant to this all-glass-and-metal product.
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.
