> not sure that it filters some of the PFOS/PFAS chemicals
Just to clarify the terminology: PFOA, PFOS, PTFE, and thousands of other chemicals are all examples that are part of a larger group of (mostly) problematic chemicals called PFAS.
That PDF has links to products certified by various certification bodies, and suggests looking for products certified against NSF 53, NSF 58, or both. but the EPA also notes the following:
> It's important to note that the current certification standards for PFAS filters (as of April 2024) do not yet indicate that a filter will remove PFAS down to the levels EPA has now set for a drinking water standard. EPA is working with standard-setting bodies to update their filter certifications to match EPA’s new requirements. In the meantime, remember that reducing levels of PFAS in your water is an effective way to limit your exposure.

Here is the EPA’s guidance on filtration standards and how to identify filters that are effective for PFAS: https://www.epa.gov/system/files/documents/2024-04/water-fil...
