Pelican PSF-1 Replacement Shower Water Filter
Lower PFAS concern; standard carbon/KDF filter media without known Teflon-family coating treatment, but brand offers no PFAS disclosure.
The PSF-1 uses activated carbon and KDF-55 media, neither of which are inherently PFAS-containing materials. Shower filters don't typically require water-repellent coatings or Teflon-type coating components.

Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The PSF-1 uses activated carbon and KDF-55 (copper-zinc alloy media) as its core filtration substrates. Activated carbon is an inert, highly porous material that traps chlorine and volatile organics through adsorption and poses no known leaching risk in warm water. KDF-55 is a well-studied media used to reduce chlorine and heavy metals via oxidation-reduction; it does not leach copper or zinc into water at the contact times and temperatures typical of shower use. Neither material is known to degrade, shed microparticles, or release harmful compounds under normal residential shower conditions.
The brand's record and disclosure
Pelican is a major U.S. water treatment brand with a long market presence and no documented safety recalls related to the PSF-1 or similar replacement cartridges. The brand provides no explicit PFAS impact statement or third-party certification (NSF, WQA) for PFAS reduction on this model. Standard industry practice for carbon-KDF filters is to avoid Teflon-family coating coatings, and Pelican's silence on the subject is typical of the category rather than a red flag; however, independent PFAS testing data for this specific model is not publicly available.
How it compares in its category
Shower filters using activated carbon and KDF-55 are among the safest filtration media available; they are non-pressurized, low-contact-time devices that do not concentrate contaminants. This product sits in the middle-tier of the replacement cartridge market in terms of transparency. Competitors often market activated alumina or ion exchange resins, which carry similar or lower hazard profiles; Pelican's combination is conventional and well-tolerated in the market.
If you buy it
Replace the cartridge every 6 months or per the manufacturer's schedule to prevent bacterial biofilm buildup in the housing and media saturation. Store replacement cartridges in a cool, dry place away from direct sunlight. Do not expose the filter housing to temperatures above 104F (40C) or freeze it. Rinse the cartridge under cold running water before installation and flush the system for 30 seconds after installing a new one to clear any carbon dust.
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.”
Bacterial growth and biofilm in filter housing
Shower filters with standing water and moist media can harbor Legionella or other pathogens if not replaced on schedule or flushed regularly. This is a maintenance issue, not an inherent material hazard; Pelican cartridges are no more or less prone to biofilm than competitors.
Carbon dust or particulate shedding during initial use
Activated carbon cartridges often release fine black particles (carbon fines) in the first few uses. This is cosmetic and not a health risk but can stain shower surfaces. Pre-flushing the cartridge cold water mitigates this.
KDF-55 media leaching under extreme conditions
KDF-55 is stable in neutral to slightly acidic water at typical shower temperatures (95-105F). No documented leaching of copper or zinc has been reported for Pelican PSF-1 in residential use. Leaching would require prolonged contact with very hot water or acidic conditions not present in shower filtration.
Housing material degradation or off-gassing
Pelican housing is typically polypropylene or similar rigid plastic rated for warm water exposure. No recalls or complaints of VOC off-gassing, plasticizer leaching, or structural failure from the PSF-1 housing are on public record.
Reduced chlorine removal effectiveness over time
As activated carbon and KDF-55 become saturated, filtration capacity drops. This is not a safety hazard to the user but indicates the filter is no longer functioning effectively; replacement on schedule prevents this.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
