> "Previous studies found the major chemical composition to be PET, which is expected since the bottle is made of PET," Yan told us. "Therefore, for a long time, we had the impression that the majority of plastic particles inside bottled water would be Polyethylene terephthalate (PET) particles of a few hundred nanometers in size."
> "That was incorrect," Yan said.
> Ironically enough, the most commonly detected plastic was polyamide, a material commonly used in water filtration systems and "the most popular membrane material used in reverse osmosis … a common water purification method shared by all three brands [of water tested]," the team wrote in the paper.
Too different from the title. And the other comments seem to have been written without reading the text.
- everdrive 3y agoThis is unfortunate news given that I have a plastic water filter on my house.
- kylebenzle 3y agoPlastic seems like an odd choice to use to drink/eat from and even stranger to filter your water. The Berkey uses a carbon filter and ceramic filters have been used for centuries. I e filtered my water through either for the last 20 years. It has always boggled my mind that people use plastic to drink out of and filter their water. Can I ask, why do you choose to use plastic rather than ceramic/carbon filter?

- everdrive 3y agoIt came with the house and I didn't think much of it. We have a well and get significant sand, iron, and a few other things without the filter. I'll probably be upgrade to carbon asap.
