> 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.
> The current system is meant to be used with municipally treated, potable water as the current filter will not remove microbiological contaminants.
