Using 3D printing, researchers developed lattices which removed up to 75 per cent of PFOA, one of the most common forever chemicals.

Pretty sure normal folks don't have indium oxide at home, nor a 3D printer that can handle the material correctly.

'Scuse me neighbor, can I borrow a spool of indium oxide filament?

"In three hours, the monoliths removed 53 per cent of perfluorooctanoic acid (PFOA), one of the most common forever chemicals also called PFAS.

Moreover, by heating the monoliths at 500°C and reusing them three times, researchers observed that at least 75 per cent of PFOA was removed."

So yeah, like 9+ hour process. Gotta cool them down between each run. I looked on wikipedia, Indium is about $167/ Kg. What if, I know this is crazy, what if we stopped poisoning the planet, and ourselves?

Even if we could stop poisoning the planet tomorrow, we still need to figure out how to deal with the mess we've created so far. The important distinction is to not let this technology development be used as a smokescreen for industries that produce PFAS, as has been done with carbon capture for the fossil fuel industry.

Perhaps the average Jane won't be making one of these filters at home, but they could perhaps be utilized in water treatment facilities to help stem forever chemical contamination in municipal water supplies. Better yet, make DuPont pay for these systems via an industry tax or punitive damages for their negligence when promoting the materials and downplaying their risks to human health. (and the environment)
