Clearly Filtered · Faucet Water Filters
Brita On Tap Faucet Water Filter System
Lower-concern filtration option, but no PFAS transparency from brand.
Brita On Tap faucet filters use activated carbon and mechanical filtration, materials with lower inherent PFAS risk. However, Clearly Filtered does not publicly disclose PFAS testing or claim PFAS-free status. The plastic housing material composition is not specified, leaving a small gap in full transparency.

The full breakdown
What it's made of and why it matters
The Brita On Tap system uses an activated carbon cartridge housed in plastic (likely polypropylene or acetal copolymer) that attaches directly to the faucet aerator. Activated carbon itself is inert and safe; the concern is the plastic housing durability and whether it leaches under repeated hot-water exposure or aging. No published material composition or BPA/BPS disclosures are readily available from Clearly Filtered for this specific model.
The brand's record and disclosure
Clearly Filtered does not publish detailed cartridge material specifications or third-party NSF/ANSI certifications for the On Tap model on their website. The brand is less transparent than market leaders like Brita (which publishes material datasheets) or PUR (which discloses NSF certification status). No recalls or contamination incidents have been publicly reported for this product line, but the brand's silence on material composition limits independent safety verification.
How it compares in its category
Faucet-mounted filters like this sit at the budget end of the market; they offer convenience but less filtration capacity than pitcher or under-sink systems. Competitors such as PUR and standard Brita On Tap models provide NSF/ANSI certifications (e.g., NSF 42, 53) that specify what contaminants are reduced; Clearly Filtered does not advertise equivalent third-party validation. Activated carbon is the industry standard for this form factor, so material risk is comparable to brands, but transparency is lower.
If you buy it
Replace cartridges every 100 gallons or 2 months, whichever comes first, to prevent bacterial biofilm buildup in the carbon bed. Do not use with water hotter than 100F (38C) as prolonged heat exposure can degrade plastic fittings. Inspect the housing annually for cracks or discoloration; discard if visible degradation appears. Flush with cold water for 5 seconds before first use and after each cartridge change to remove loose carbon particles.
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.”
Plastic housing leaching (BPA/BPS/other organics)
No material specification published by Clearly Filtered. Repeated exposure to cold and warm water may cause slow leaching from polypropylene or acetal housing, but risk is lower than with direct-contact drinking vessels due to brief contact time. Age and UV light exposure can increase leaching risk.
Bacterial biofilm in filter cartridge
Activated carbon filters are known to harbor bacteria if not replaced on schedule or if water sits in the filter between uses. Faucet-mounted filters are particularly prone to this because they are exposed to air when not in use. Clearly Filtered provides no guidance on antimicrobial treatment or testing protocols for this model.
Cartridge loose carbon particles
New activated carbon cartridges can shed fine black particles, especially if not flushed before first use. While activated carbon itself is food-grade and non-toxic, visible particles in drinking water are undesirable and indicate improper installation or cartridge degradation.
Faucet aerator compatibility and wear
The attachment mechanism may not fit all faucet types and can loosen over time, creating dead spots where water stagnates. No installation instructions or troubleshooting guidance are prominently available, risking improper use that increases biofilm risk.
Lack of contaminant-reduction certification
Unlike NSF 42/53 certified competitors, Clearly Filtered does not publish third-party verification of what this filter actually removes (e.g., chlorine, lead, cysts). Consumers cannot independently verify performance claims, making it harder to assess whether the product meets their water quality needs.
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.
