PUR Maxion Faucet Water Filter PFM150W
Lower concern for this filter type, though no public PFAS disclosure from brand.
Faucet filters use activated carbon and ion-exchange resin, standard materials with lower PFAS risk than treated fabrics or nonstick coatings. Brand makes no PFAS claims for this model; no third-party verification is public.

What PUR Maxion Faucet Water Filter PFM150W is made of, ingredients and materials
The PUR Maxion PFM150W uses activated carbon as its primary filtration medium, a well-established material for reducing chlorine taste, odor, and some organic contaminants. The cartridge housing is typically polypropylene or similar food-grade plastic. Activated carbon itself is inert and does not leach harmful substances under normal drinking water conditions; the main performance variable is how thoroughly the carbon is manufactured and how quickly it becomes saturated. This design avoids Teflon-type coating (Teflon) and ceramic coatings that present fume risks in other filter types.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial growth in filter cartridge
Activated carbon provides a porous medium where bacteria can colonize if cartridges are not replaced on schedule or if the filter sits unused for extended periods. This is a maintenance issue, not a manufacturing defect, but undisclosed or overdue cartridges can degrade water safety.
Filter cartridge saturation and reduced efficacy
User reports and product reviews document that filters lose effectiveness before the stated 100-gallon life if water quality is poor or chlorine levels are high, leading to false confidence in contamination reduction. This is a performance rather than toxicity hazard but affects safety outcomes.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Polypropylene housing leachables
Food-grade polypropylene used in the filter housing does not typically leach BPA or phthalates at room temperature drinking water conditions. No recalls or reports of leaching from PUR faucet filter housings are on public record.
Teflon-type coating or coating-related fume risk
The PFM150W does not use Teflon-type coating-based coatings or ceramic glazes, so there is no risk of fume generation during normal use or cartridge handling.
Lead
Activated carbon itself does not leach lead, cadmium, or other heavy metals into water under normal pH and temperature conditions. No testing records or recalls document this hazard for PUR Maxion products.

The brand's record and disclosure
PUR is owned by Helen of Troy and has a long track record in water filtration but does not publicly disclose PFAS removal testing results for the Maxion line, which is typical across the faucet filter category. The brand has not faced major recalls or safety controversies specific to this product model. PUR holds NSF certification for some products but certification specifics for the PFM150W should be verified on packaging or the brand website, as claims vary by model.
How it compares in its category
Faucet filters like this one are entry-level, lower-cost solutions compared to pitcher filters or under-sink systems; they offer convenience but typically filter less water volume and may miss some emerging contaminants like PFAS at high removal rates. The Maxion is positioned as a mid-tier faucet option, offering filter life of around 100 gallons (roughly 2-3 months) versus some competitors claiming up to 200 gallons. Activated carbon is the standard across most faucet filters, so material risk is consistent with the category.
If you buy it
Replace cartridges on schedule or when flow slows noticeably; carbon filters do not improve with age and can harbor bacterial growth if left beyond recommended use. Store replacement cartridges in a cool, dry place to preserve carbon function. Do not attempt to reuse or clean cartridges; once saturated, they lose effectiveness. Monitor water taste and odor as a practical indicator of cartridge exhaustion, since filter life depends on local water quality and usage.
