For the most part, trying to not drink water out of a plastic bottle is really advisable because that is a big source of microplastics ... Any type of activated carbon filter will filter out a lot of the plastic-associated chemicals, but if you really want to filter out all these microplastics in all their sizes... a reverse osmosis filter at home, whether it's a tabletop one that you just drink your water out of or it's a whole-home filtration system, is the way to go because it does filter out even the nanoplastics.
