PFAS score
Aqua Guard · Under-Sink RO Systems
Aquaguard Ritz RO+UV Taste Adjuster Stainless Steel Copper Water Purifier
Lower PFAS concern for this RO+UV system; stainless/copper hardware and standard membrane filtration are not known PFAS sources.
Aquaguard Ritz uses stainless steel and copper construction with RO and UV filtration, none of these are typical PFAS application points. RO membranes and UV units do not require Teflon-type coating or Teflon-family coating coatings.

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.
