Lifeproof Next Series Dirt + Drop-Proof Case for iPhone 11 Pro
Skip until Lifeproof discloses waterproofing chemistry.
Lifeproof's waterproof phone case uses coatings to repel water and dirt, but the brand does not disclose PFAS presence or absence. Waterproof coatings commonly contain PFAS; unconfirmed chemistry is a concern.

The full breakdown
What it's made of and why it matters
This case combines polycarbonate (a rigid plastic) with thermoplastic elastomer (flexible rubber-like plastic) to absorb impact and maintain the phone seal. The waterproof coating is the concern: Lifeproof does not publicly specify whether it uses PFAS-based hydrophobic treatments, which is standard in the water-protection industry. Polycarbonate and TPE themselves are stable when intact, but the proprietary coating's chemistry remains opaque.
The brand's record and disclosure
Lifeproof (owned by OtterBox/Essentials) has not published detailed material safety data sheets or waterproofing chemistry specifics in publicly available documentation. The company does not claim PFAS-free status or provide third-party testing results for the coatings. This silence around a key ingredient in waterproof cases is a known industry pattern where PFAS use is common but undisclosed.
How it compares in its category
Lifeproof occupies the mid-to-premium drop-proof segment; competitors like OtterBox Defender and Spigen Tough Armor also use polycarbonate/elastomer shells with undisclosed coatings. Some brands (Pela, Casetify) have committed to PFAS-free claims, though verification is limited. Lifeproof's lack of transparency is typical for the category but not a distinguishing feature, most waterproof case makers remain silent on this issue.
If you buy it
Store the case away from direct heat sources (over 140F/60C) to minimize polymer stress and coating breakdown. Clean with mild soap and water only; avoid harsh solvents that could degrade seals. Inspect the rubber gasket annually for cracks or loss of elasticity, as degradation can let moisture in. Replace the case if the waterproof seal shows visible damage, as these are not field-repairable.
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.”
Undisclosed waterproof coating (likely PFAS-based)
Lifeproof's waterproof treatment chemistry is proprietary and not disclosed. Industry standard for water-resistant cases involves PFAS, but no public testing or recall exists for this specific product. Coating degrades over 2-3 years of use and may shed particles or leach into phone or hands; this has not been documented as a reported safety event.
Polycarbonate degradation under UV/heat
Polycarbonate can yellow, become brittle, and potentially leach bisphenol-related compounds when stressed by prolonged UV exposure or heat above 140F. The case is not typically exposed to extreme sustained heat if kept in a normal pocket or bag, so this is a low-probability hazard under typical use.
Elastomer material off-gassing
Thermoplastic elastomer used in drop-protection does not typically off-gas volatile organic compounds under normal conditions. No documented off-gassing complaints or recalls for Lifeproof cases exist. The material is stable when the case is not exposed to solvents or extreme heat.
Bacterial growth in waterproof seals
Tight rubber gaskets and enclosed air pockets in waterproof cases can trap moisture if not dried completely after water exposure, creating conditions for mold or bacterial growth. This is a maintenance and care issue, not a material defect; regular air-drying prevents it.
Lead or cadmium in colorants
No recalls or testing reports indicate heavy metal contamination in Lifeproof case dyes or pigments. Polycarbonate and TPE-based cases are not typically vehicles for lead/cadmium exposure compared to ceramics or paints, so this hazard is not established for this product category.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
