I know that Reverse osmosis membranes are able to prevent these from passing. That's what I installed at home for drinking water for this exact problem.
You're likely thinking of microplastics not nanoplastics. RO is actually suspected of ADDING nanoplastics

Thanks for the link. That's interesting to me. I was not confused about nano vs micro plastic. In my research before installing, I see the membrane size is about 1/10th that of nanoplastic size, hence thought it would remove them. For microplastic most non-RO filters can already remove them.
So what does that leave us with to filter water absolutely safely? Distillation? Are there any commercial or consumer systems that can do that in an easy and convenient package?
The only alternative to RO/Distillation in purity I can think of is collecting rainwater. Im still going to use RO. For the volumes of water I use and without a rainwater collection system that doesn't use plastic pipes it's the best I can do.
While it may introduce nanoplastic it also removes it from the source water so depending on the numbers it may still be better
