Delta Reverse Osmosis Contemporary Faucet DWQ4001002-SS
Lower concern. RO/carbon filters and stainless steel typically avoid PFAS.
Delta's reverse osmosis faucet uses stainless steel and standard RO/carbon filtration. No PFAS disclosure found, but materials are not typical PFAS sources.

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.
