TLDR: Calcium binds to the microplastics making them easier to filter. You have to boil > cool > filter. Works better with hard water.

Filtering drinking water can remove microplastics. (After boiling)

FTFY

instructions unclear drinks boiling water

[–] moondaddy@piefed.social 3 points 3 months ago

Been doing this for years. Boil a gallon, let it cool, put it through charcoal filter. And my water is also hard so the boiling helps precipitate a lot of the minerals out. BTW Brita filter cartridges can be refilled if you drill a hole in the top, dump it out and replace with activated charcoal. This also saved my heart because when I got the minerals out, I stopped having angina.

Wouldn't this also just put a lot of them into the air? We know both nano and micro forms can be found in atmosphere, so it would seem this would displace a portion from the water into the air via steam, no?

binds to calcium.. becomes particulate large enough for filtration

I get that part, but that can't be the entire volume of everything in the water.

i can see it now...

~~conservatives~~ fascists; 'hey, heres a nifty 300$ filtration system you can install that will automatically boil and filter on your behalf, american made!'

~~democrats~~ conservatives; ' we have a guarantee by all major manufactures who can spell plastic to join a committee to potentially reduce plastic use by 4% over the next 75 years! until they, boil your shit. '

~~progressives~~ democrats; 'no regulation says whhhhhat?'

This...

This is exactly how we got into this mess

People don't like consuming pieces of plastic, so we'll break it down into pieces so small they can't be detected!

I can't wait to freak out about teeny-plastics in 2045 and hear about how they're poisoning my balls and brain

Pre-emptive edit:

Yes, I'm aware that the article says the heat causes calcium to crystalize around the plastic then needs filtered out. If you believe heat that high isn't causing very very small (and undetactable) pieces of plastic are coming off...
