PFAS in Waterproof Phone Cases, Which Brands Grade Best and Worst

Waterproof phone cases rely on tight-sealing gaskets, hydrophobic coatings, and rubberized polymers to keep water out, and those same properties are exactly where PFAS ("forever chemicals") tend to show up in consumer products. Based on the waterproof phone cases in our database with published grades, every model we've reviewed so far comes from a single brand, LifeProof, and every one of them lands in the same "Poor" tier with a model-based safety score of 40 out of 100. That is not a close call between winners and losers; it is a category where, so far, nothing has cleared the bar.

So the clear takeaway up front, based on available materials and data, there is no LifeProof waterproof case in our database that qualifies as lower concern, and no brand in this specific category has separated itself from the pack. If you're shopping for a waterproof case today, treat this guide as a "what to avoid and why" reference rather than a straightforward "buy this one" recommendation, and use our product finder to check any specific model before you buy.

Summary Comparison

Product	PFAS Grade (Model Estimate)	Verdict
LifeProof FRE Case for iPhone 11 Pro	Poor (40/100)	Higher concern; avoid if minimizing PFAS exposure is a priority
LifeProof FRE Series Case for iPhone 11 Pro Max (Non-Retail Packaging)	Poor (40/100)	Higher concern; same core construction as the standard FRE line
LifeProof FRE MagSafe Series Case for iPhone 13 Pro	Poor (40/100)	Higher concern; newer MagSafe design does not change the score
LifeProof Next Series Dirt + Drop-Proof Case for iPhone 11 Pro	Poor (40/100)	Higher concern; drop-proof design does not offset materials profile

Product-by-Product Breakdown

LifeProof FRE Case for iPhone 11 Pro

This is LifeProof's flagship fully submersible case, built around a multi-layer polycarbonate shell with rubberized, gasket-sealed ports designed to keep the phone usable underwater. Based on available materials and data, cases in this construction category commonly rely on synthetic rubber and polymer seals where fluoropolymer or PFAS-adjacent additives can be used to improve water and grease resistance, which is reflected in the model's Poor (40/100) score, our model-based estimate from materials and public disclosure, not a lab test.

Brand claims, LifeProof markets the FRE line as waterproof to 2 meters and dirtproof, snowproof, and dropproof. These are brand-stated performance claims about water resistance, not third-party verified statements about chemical composition.

Pros, Strong physical waterproofing performance, drop protection, widely available, established repeat product line.

Cons, Poor grade in our model, no published third-party PFAS testing disclosed by the brand that we found, sealed gasket design that is difficult to disassemble or recycle.

LifeProof FRE Series Waterproof Case for iPhone 11 Pro Max (Non-Retail Packaging)

This is functionally the larger-phone version of the same FRE construction, sold in bulk or non-retail packaging, often through third-party resellers. Materials and sealing approach appear consistent with the standard FRE case, which is why it carries the identical Poor (40/100) score in our system.

Brand claims, Same waterproof, dirtproof, and dropproof claims as the retail FRE packaging; non-retail packaging typically reflects a distribution channel difference, not a materials difference.

Pros, Often cheaper than retail-boxed versions, same protective performance as the standard FRE case.

Cons, Same materials concerns as the standard FRE case, plus less transparency around sourcing when purchased through bulk or non-retail channels.

LifeProof FRE MagSafe Series Waterproof Case for iPhone 13 Pro

The MagSafe-compatible update to the FRE line adds a magnetic ring for wireless charging and accessory attachment, but the core waterproofing shell and gasket system are built on the same design philosophy as earlier FRE models. This is reflected in the same Poor (40/100) score.

Brand claims, LifeProof states this case is waterproof, MagSafe compatible, and drop-tested; these are performance and compatibility claims, not independently verified chemical safety claims.

Pros, Adds modern MagSafe convenience without sacrificing waterproof performance, drop protection comparable to earlier FRE models.

Cons, Newer release does not translate into a materials improvement based on available data; still scores Poor in our model.

LifeProof Next Series Dirt + Drop-Proof Case for iPhone 11 Pro

Unlike the fully submersible FRE line, the Next Series is dirtproof, snowproof, and dropproof but not designed for full water submersion. Despite the lighter-duty sealing requirements, it still scores Poor (40/100) in our model, based on available materials and data about the polymer and rubberized components used.

Brand claims, LifeProof positions Next as a rugged, open-back case that skips full waterproofing for a lower-profile design; it does not claim full waterproof submersion.

Pros, Slimmer and more open design than fully sealed cases, drop protection, no full gasket sealing around ports.

Cons, Still carries the same Poor score as fully submersible LifeProof cases, suggesting the concern is tied to broader material choices across the product line rather than the sealing method alone.

What to Avoid

• Vague "waterproof coating" language with no ingredient or polymer disclosure. If a brand won't name what the water- and grease-resistant coating is made of, treat that as a red flag rather than reassurance.
• Marketing claims of "eco-friendly" or "safe" waterproofing with no supporting test data. A brand-stated claim is not the same as a third-party verified result, and none of the products in this guide come with independent lab disclosure we could confirm.
• Assuming a higher price or premium brand name means a better materials profile. All four LifeProof cases reviewed here, spanning multiple iPhone generations and two different product lines, scored identically, which suggests the concern sits at the brand or manufacturing-process level rather than in any single model.
• Non-retail or bulk-packaged versions of the same case, assuming they differ from retail versions. Based on available data, packaging channel does not appear to change the underlying materials profile.

Our Pick

Based on available materials and data, we are not able to name a "lower concern" waterproof phone case from the products currently in our database; every graded model here, across LifeProof's FRE, FRE MagSafe, and Next Series lines, lands in the Poor tier at 40/100. Rather than force a recommendation that the data doesn't support, our honest guidance is this, if avoiding PFAS-associated materials is a priority, consider whether you need full waterproof submersion at all, since dirtproof/dropproof-only designs and simple silicone sleeves may carry a different materials profile, though none of those alternatives have been graded in our database yet either. Use our product finder to check for newly graded phone cases before you buy, and if you're evaluating waterproofing more broadly across your gear, our camping gear and outdoor waterproofing finder covers related sealed and water-resistant products with their own independent grades.

Does a "Poor" grade mean this phone case definitely contains PFAS?
