Getting microplastic out of the water is important.
But in the long run that’s not the solution. Microplastic is not just in the water, but everywhere, like in the soil. Textiles not only shed plastic when you wash them, but even more when you wear them. Solution: don’t buy. Use natural fibres.
Same with plastic utensils, cups, plates, containers etc.: don’t use! There have been alternatives for (almost) as long as humans exist. From wood to metal to ceramics to glass.

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/
Consumerist changes are not a solution to anything, government regulation is.
