A recent study (made it to HN) used a novel sensor to count microplastics in bottled water. The numbers were 10x higher than expected, but the real surprise was that 50% were shed from the plant filtration system.
I’m guessing RO is similarly bad (the membrane is made from one of the plastics in question).
- engneeer 3y agowhich study was that? anyone got the link? thanks!

- camkego 3y agoI have been buying 5gal water jugs from a local Seattle company until recently, with the articles on all the microplastics shedding from the bottles into the water inside. I did buy no-plastics Aarke glass/steel carbon filter pitcher for my drinking water. It's hard to find water filtration without plastic involved, hopefully other options will come to the market, but their offering is pretty good so far.

What about distillation as a filtration method? Are the micro/nano plastics filtered by distillation? Interesting what method of filtration the chip factories use, as they need 100% pure water for the cpu making process.
- bruce343434 3y ago100% pure water sucks the salts and electrolytes out of your body though, so you'd need to dope it again with some minerals
- infecto 3y agoIts not that interesting. Distillation works but its not healthy to consume. You could distill the water without plastics involved but then you need to add back minerals before drinking.

- noduerme 3y agoWater is hardly the worst of it. Most people I know microwave food in plastic on a regular basis, and have been doing so for decades. If you wonder about the crazy rise in colon cancer, I'd say doing that plus keeping a cellphone next to your ass 16 hours a day would definitely be more than enough in an animal model.
- doctorhandshake 3y agoIDK about the cell phone radiation but given the trickle/torrent of bad indicators about our biology and plastic, my rule is no plastic near food, at least at home where I can control it. Definitely no freezing, heating, or microwaving plastic near food. Feels like one of the many accepted facets of space-age modern life that is too convenient to examine closely for most people, and I think it retrospect it will be viewed somewhat as we view lead in paint and fuel, asbestos in buildings, smoking in public, etc.
- galangalalgol 3y agoWe use a distiller now that is all stainless into a glass carafe. It has a small paper/charcoal filter that sits in a porcelain housing just before it drips. What is left over is gross. Not what it looks like, that is just minerals. But it smells like things I shouldn't be smelling. I'd like to build a glass only solar still to save all that power, and to avoid the high temps that I suspect are causing some reactions that release VOCs. Not all of which might be getting caught by the charcoal.
