> ZeroWater makes a carafe that reduces total dissolved solids to 0 ppm, including PFAs and microplastics, or so they claim.

ZeroWater uses an ion exchange filter - It's my understanding that many (most?) micro plastics are not dissolved and/or are not charged meaning it won't effectively filter most microplastics.

Similarly they aren't designed to filter bacteria.

They do manage to filter inorganic solids, but I’m not sure about microplastics. I assumed they did, but they’re hesitant to say on their site. Perhaps I mistakenly assumed that if they can eliminate PFAs from water, microplastics are also removable.
