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.
This system uses stainless steel and copper construction with RO and UV filtration, none of which are typical PFAS application points. RO membranes and UV units do not require Teflon-type coating or Teflon-family coating coatings.
