Especially considering that the oil filter in your car is good to tens of microns for tens of thousands of gallons and costs ~$5.

You'd think that if you're running an industrial plant (at a scale where multi-stage filters, centrifugal separation, etc, etc are economically viable) you'd be able to do a heck of a lot better than 10 100 micron particles per liter.

To be fair, I think these microplastics accumulate in the water after they have been bottled.

I didn't think it had anything to do with plastic from the bottles the water is sold in. Where is that assumption coming from?

"It's not clear how the plastic is getting into the bottled water — whether it's the water source itself or the air or the manufacturing and bottling process.

"Even the simple act of opening the cap could cause plastic to be chipping off the cap," Mason said."

I assumed the reason bottled water tastes strongly of plastic was because the plastic of the bottle was leeching into the water.
