Of course, we need government action! But do you know the micro plastic content coming from tap water? Do you have much of a choice as to what you are consuming? Wouldn’t you want to filter it out?
As far as technology, this isn’t pie in the sky, it seems fairly simple and I wouldn’t be surprised if home-made solar punk versions start appearing in zines and online forums.
Of course we need stop producing plastics, or at least the types that break down so easily.
But even then, the micro plastics will likely remain in the environment for some time, so efforts to filter them from water are important. Especially considering as some of the health effects are only starting to become apparent. See https://www.uri.edu/news/2023/08/microplastics-infiltrate-all-systems-of-body-cause-behavioral-changes/
