Digital HT Twin Pack UVP & CP Screw-In Filter Kit
Lower concern. Camera filters use glass and aluminum, not typical PFAS sources.
This filter kit contains glass optics and aluminum threads, materials not commonly treated with PFAS. No brand disclosure on PFAS exists, but the product category poses minimal typical risk.

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.
Glass fragmentation and sharp edges
Dropping an optical glass filter can cause breakage, producing sharp fragments. This is a mechanical hazard, not a chemical one. Proper storage in a padded case eliminates this risk.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
Optical coatings on professional glass filters typically use rare-earth oxides and titanium compounds, not lead or cadmium. No recalls or safety alerts exist for Tiffen or generic optical filters on these grounds.
Source, ATSDR ↗Aluminum leaching from threads
Aluminum filter threads contact air and light only; they do not contact food, water, or skin. Anodized aluminum is chemically stable and poses no leaching hazard in this non-consumptive application.
Mold or bacterial growth in sealed filter housing
Screw-in filters are passive optical elements with no sealed chambers, water retention, or replacement media. Unlike water filters or encased lens elements, this kit has no internal environment for microbial growth.
Off-gassing or volatile organic compounds (VOCs)
Glass, aluminum, and optical cement do not emit VOCs at room temperature. No adhesives or polymers in significant quantity are present in standard filter construction.
The full breakdown
What it's made of and why it matters
This filter kit uses optical glass as the primary light-transmitting element, mounted in aluminum threaded rings, with minimal plastic or adhesive components. Optical glass does not leach chemicals during normal use and is chemically inert. Aluminum threads are anodized or bare, and pose no ingestion or dermal risk in this application since the filter sits external to the camera body and never contacts skin, food, or beverage.
The brand's record and disclosure
Tiffen is a long-established optics manufacturer with no significant product safety recalls or chemical disclosure violations on record for camera filters. The company does not publicly disclose PFAS policies, but camera filter products do not typically employ PFAS-containing materials. No independent testing or third-party certifications (e.g., RoHS, heavy-metal limits) have been publicly documented for this specific kit.
How it compares in its category
Camera filter kits across brands (Canon, Nikon, generic) share identical material profiles, optical glass, metal threading, and negligible plastic. This product is materially equivalent to competitors. UV and circular polarizer filters are mature optical products with decades of consumer use; there is no performance differentiation among major brands.
If you buy it
Store filters in a cool, dry case to prevent dust accumulation and lens fungus (a maintenance, not toxicity, concern). Handle glass elements by edges only to avoid oil smearing. No heat limits apply; aluminum and glass are stable across consumer temperature ranges. Inspect threads yearly for corrosion if exposed to salt air or high humidity; replace only if threading becomes damaged and causes vignetting.
