Compare Food Storage Containers
Which scores higher on safety? R3 breaks it down.
The most important dimensions, side by side.
Borosilicate glass is the gold standard for food-contact safety — chemically inert, handles freezer-to-oven transitions without shattering, and zero chemical migration.
Soda-lime glass is chemically inert and FDA-approved — safe for daily food contact. Pyrex US uses tempered soda-lime (not borosilicate), which means you should avoid sudden freezer-to-hot-oven transitions.
OXO does not disclose the specific plastic type used in the lid. While it includes a silicone gasket and is BPA-free, the lack of material transparency is a concern since the lid contacts your food directly.
BPA-free polypropylene lids are FDA-approved and safe at normal storage temperatures — a reliable plastic choice for food-contact lids.
Confirmed BPA-free for both the borosilicate glass container and plastic lid components.
Confirmed BPA-free for both the glass containers and polypropylene lids.
OXO has not published PFAS-free testing for the silicone gasket or lid — common across most brands in this category.
Pyrex has not published PFAS-free testing for the lid material — common across most brands in this category.
Borosilicate glass goes from freezer to preheated oven without needing to thaw first — full versatility for reheating, baking, and roasting.
Oven-safe to 425°F in a preheated oven — suitable for reheating and light baking, but avoid broiling or rapid temperature changes.
Four locking tabs with a silicone gasket create a fully leakproof, airtight seal — safe for soups, sauces, and anything you need to transport.
Press-fit lids sit on top without locking or sealing — adequate for refrigerator storage but will not prevent leaks during transport.
Both glass container and lid are fully dishwasher safe.
Both glass containers and PP lids are dishwasher safe — containers on any rack, lids on the top rack.
Four locking tabs require two hands to open and close — slightly frustrating for quick refrigerator access but the trade-off for a leakproof seal.
Simple press-fit lids lift on and off with one hand — the easiest daily use in this comparison, trading seal security for convenience.
Stacks neatly in the fridge or freezer and nests in the cabinet when stored without lids.
Round containers nest inside each other and rectangular containers stack flat — efficient for both fridge organization and cabinet storage.
Everything you need to make the call - who each one is for, and who should skip it.

The main thing to know
OXO does not disclose the specific plastic type used in the lid. While it is BPA-free with a silicone gasket, buyers who want full material transparency should consider alternatives like Glasslock that disclose PP lids.
The press-fit lids are not airtight or leakproof. Pyrex Simply Store is designed for home refrigerator use — if you pack lunches or transport food, these lids will shift and leak.
Skip this if you...
You want full material transparency on lid composition — OXO does not disclose the specific plastic type
You prefer one-handed convenience — the 4-tab locking mechanism requires two hands
You need a budget-friendly set — at $14.99 per single container, a full set adds up quickly
You need leakproof containers for transporting lunches, soups, or liquids
You want borosilicate glass — Pyrex US uses soda-lime glass since 1998, which has thermal shock limitations
You want PFAS-free verification on lid gasket materials
