Ghostek Nautical Slim S25 Waterproof Case Screen Protector and Camera Lens Cover Rugged Magnetic MagSafe Compatible
Skip until brand discloses waterproof treatment chemistry; high uncertainty on coating source.
This rugged phone case relies on waterproof/water-resistant technology typical of smartphone cases, often achieved via Teflon-family coating or PFAS-based water-repellent coating treatments, but Ghostek provides no public disclosure of the specific coatings used.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
