These guys claim their filters are good for this: https://www.hydroviv.com/blogs/water-smarts/duke-nc-state-pf.... I use these filters, but no idea about the validity of their marketing on this.

NSF at least certifies their claim.

That's a surprisingly small volume of water though. I also don't love how private they are about what the filter media is.
