Waterproof Camera Filter
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes glass or optical resin, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Waterproof Camera Filter is made of, ingredients and materials
Waterproof camera filters are constructed from optical-grade glass or specialized optical resin (likely acrylic or polycarbonate) with no applied protective coating described in public specifications. Glass is chemically inert and will not leach or degrade under normal use or light exposure. If resin-based, the material itself is stable; the waterproofing comes from the sealed optical construction and gasket design, not a surface treatment that could off-gas or break down.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Optical resin thermal degradation
If the filter core is acrylic or polycarbonate resin (not glass), prolonged exposure to direct sunlight or temperatures above 60°C may cause slight warping or stress-crazing. This affects optical clarity but not chemical safety.
Gasket/seal material degradation
Rubber or silicone gaskets used to create the waterproof seal can degrade over years of UV exposure or repeated thermal cycling, compromising waterproofing. No toxic outgassing known, but loss of function is likely.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leachables from optical resin
No reports of BPA, phthalates, or other endocrine disruptors leaching from optical-grade acrylic or polycarbonate filters under normal (non-heated) use. These polymers are treated differently from food-contact plastics.
Heavy metals
The brand does not describe an applied anti-reflective or protective coating on this filter. Without an applied coating, no cadmium, lead, or antimony hazard applies.
Source, FDA ↗Microplastic shedding
Optical filters are rigid and not flexible; they do not shed microparticles during normal use or cleaning with soft brushes.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand has a mixed transparency record on chemical disclosure. The company has faced litigation over PFOA/PFAS in legacy products but does not routinely volunteer PFAS statements for optical or protective equipment lines. For this specific filter product, no safety data sheet warnings, recalls, or chemical concerns have been publicly documented. The brand's silence on PFAS for a glass/resin optical filter is consistent with the product's simple construction.
How it compares in its category
Waterproof camera filters in this category typically use similar materials, borosilicate glass or optical polymers without added coatings. The brand's offering is standard-class; no performance or safety advantage or disadvantage versus unnamed competitor filters made of the same base materials. The waterproof seal depends on gasket integrity and design, not chemical treatments, whereas filters with undisclosed hydrophobic coatings may rely on added chemistry.
If you buy it
Store the filter in a dry case when not in use to preserve gasket integrity. Do not expose to prolonged heat above 50 degrees Celsius, as resin bases may soften. Rinse with distilled water if exposed to salt spray; dry immediately to avoid mineral deposit buildup on optical surfaces. Replace gaskets every 2-3 years if the filter is used in high-humidity or submersion environments, or if you notice water seeping around the edge.
