Quantum QUS Quantum Ultra Stacking & Hanging Acrylic Crystal Clear Bins, By Multiples 8-1/4" / 14-3/4" / 7"
Lower concern. Clear acrylic bins have minimal PFAS risk profile.
Acrylic storage bins are inherently unlikely to contain PFAS, as they require no water-resistance or nonstick treatment. No brand disclosure about PFAS, but material itself presents lower concern.

The full breakdown
What it's made of and why it matters
These bins are cast or injection-molded polymethyl methacrylate (PMMA), commonly called acrylic or plexiglass. Unlike polycarbonate (PC) or polystyrene (PS), acrylic is chemically inert at room temperature and does not leach BPA, phthalates, or other endocrine disruptors into stored goods. The material is rigid, non-porous, and resistant to moisture and mild solvents, making it stable for dry goods storage across temperature ranges typical of home and workshop use.
The brand's record and disclosure
Quantum Storage Systems is a manufacturer of modular storage solutions with no publicly documented recalls, safety certifications, or transparency statements specific to chemical composition. The brand makes no published claims about PFAS avoidance, phthalate-free status, or third-party testing. However, no adverse events or chemical concerns have been raised in consumer reports or regulatory filings for this product line. The company's silence on material sourcing reflects industry norms for generic resin suppliers rather than a red flag.
How it compares in its category
Acrylic bins are safer than polycarbonate (which can leach BPA) and more durable than polyethylene terephthalate (PETE/PET), which can develop stress fractures and microplastic shedding. They rival polypropylene (PP) in chemical inertness but offer superior optical clarity and scratch resistance. Among clear rigid plastics for food-adjacent or dry storage, acrylic sits in the low-hazard tier, second only to borosilicate glass in safety profile.
If you buy it
Store dry goods, hardware, craft supplies, and non-food items without concern. Avoid sustained exposure above 70°C (158°F) or direct UV sunlight, which can cause crazing and yellowing over time. Clean with mild soap and water; do not use harsh solvents, acetone, or abrasive scrubbers, as these can cloud the acrylic. Replace if cracks develop or interior surfaces become brittle, though this is rare under normal storage conditions.
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.”
Microplastics shedding from mechanical stress
Repeated stacking, dropping, or friction can generate micro-particles of acrylic. Risk is minimal if bins are handled gently and stored away from abrasive contact; concern is only significant if particles enter food or drinking water.
Crazing and stress fracturing over time
Prolonged exposure to UV light, temperature cycling, or chemical solvents (acetone, strong cleaners) can initiate hairline cracks in acrylic. Once cracked, structural integrity declines and microscopic fragments may shed; however, this develops over years of poor storage conditions, not normal use.
Yellowing and optical degradation
Clear acrylic naturally yellows under sustained UV exposure, reducing optical clarity but posing no chemical hazard to stored contents. This is cosmetic degradation, not a safety issue.
Volatile organic compounds (VOCs) off-gassing
Molded acrylic bins release negligible VOCs at room temperature after manufacturing; off-gassing is not a documented concern for this product class in indoor storage use.
Thermal leaching or warping
Acrylic is stable below 70°C and does not leach monomers or plasticizers when used for room-temperature storage. Risk of leaching into stored contents is absent under normal household conditions.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
