PFAS are long-lived chemicals, and PFOA and PFOS are the two most common in drinking water. Waterdrop's PFAS page says reverse osmosis puts a 0.0001 micron membrane between those compounds and your glass.
The company is careful on one point: performance varies by model and by your water conditions. Its listings say reductions for PFOA, PFOS, lead, fluoride and arsenic come from third-party laboratory tests.
On paper, NSF/ANSI 58 covers RO systems and requires at least 75% TDS reduction and 96.7% lead reduction. Waterdrop's NSF page marks PFOA and PFOS reduction under NSF/ANSI 58 and 53, so read each product's data sheet for the exact claims.
Models that its PFAS page lists with NSF/ANSI 42, 53, 58 and 372 are the G3P800 and G3P600, while X12 and X16 show 42, 58 and 372. The M6 countertop line is listed under 58 and 372.
For PFAS-focused households, a compact way in is the M6 countertop line, with the $70 off on its hot model. Under the sink, G3P600 and G3P800 are the ones with the longest certification lists.

Does Waterdrop say RO reduces PFOA and PFOS?
Yes. It states that its 0.0001 micron RO membrane reduces them, with the caveat that results vary by model and water conditions.
Which models list NSF/ANSI 58?
M6, G3P600, G3P800, X12 and X16 are listed with it on the official pages.
Is there independent testing behind the claims?
The listings refer to third-party laboratory tests and an IAPMO R&T certificate. Open the report linked on each product page for the exact figures.
Does this address well water?
The official pages do not make a well water claim, so rely on a lab test of your own supply before choosing a system.
