Interesting, I used ZeroWater for a while … and know others that do. But yeah, searching around it seems it’s only ConsumerLabs.com that came up with that result and all other filters were removing (at least some percentage of) microplastics.

I’m not sure how much I trust that ConsumerLabs.com test: https://www.consumerlab.com/methods/water-filters-review/water-filters/

Repeatability isn’t really established by testing one device, one time. I’m not an expert either, but that result seems quite surprising.

I have a reverse osmosis system now personally…
