If this can be commercialized into an at-home filter that's easy to install and use, you can absolutely bet that this would be advertised to hell and back and make a fuckton of money from people convinced of the absolute need to filter out microplastics.
Of course, no direct adverse health effects have ever been proved from them, but wouldn't you pay $30 for a filter, just in case? I guarantee you millions of people would.
The shareholders don't want you to become living plastic; they want you to buy shit, and this is a very obvious product that would make a lot of money.
