Pick up the habit of using a glass bottle. No plastic leech and it pays for itself in a couple months.
if you have a sink you can install a pressure-fed filter and never have to worry about this shit. I’ve replaced the internal membrane once every other year for 50 bucks. It’s cheap, safe, and the filter is good for viruses, heavy metals and PFAS, which makes it even better than bottled water.
Genuine question: what kind of filter would catch microplastic and viruses?
This is the best summary I could come up with:
The average store-bought bottle of water contains somewhere in the neighborhood of 10 to 100 times more minute plastic particles than previously believed, judging from a study published this week.
We’ve long known about the presence of microplastic particles in bottled water and proliferating through nature, while nanoplastics (pieces less than a micron, or 0.001 mm) have been difficult to accurately measure.
“It is not totally unexpected to find so much of this stuff,” Columbia graduate student Naixin Qian, lead author of a PNAS-published paper describing this study, explained.
Previous studies of micro and nanoplastics in the water and food supply have linked them to reproductive abnormalities, increased mortality, oxidative stress and other biological harms to humans and other animals.
“Compared to the traditional Raman technique which may need days to map a filter surface, SRS only needs several hours for a sample,” Beizhan Yan, associate research professor at Columbia and one of the study’s authors, told The Register.
While SRS has allowed the team to say with confidence that they’ve determined there are orders of magnitude more plastic in bottled water than previously believed, there’s still a lot the study’s method isn’t able to detect.
