      I read the article. Apparently it only really works with hard water - that’s water with a high concentration of calcium carbonate. At high temperatures, the calcium carbonate becomes a solid, trapping the microplastics inside it, which is then removed from the water with a regular filter.

        So, the boiling doesn’t remove it at all; it pre-treats hard water, making it capable of being filtered out afterwards.

            “calcium carbonate in the (hard) water became solid at higher temperatures, trapping the plastic particles within”

            No gas involved. They did recommend straining the boiled water through a coffee filter and the harder the water the better.

            By causing it to be absorbed into the calcium carbonate that is in hard water

            The calcium carbonate in hard water precipitates out when you boil it, i.e. it turns solid.

            Microplastics make for great nucleation points for the calcium carbonate to latch onto. So, the microplastics became super easy to filter out of the water (with some getting stuck to the bottom of the kettle in that white scale that you have to use vinegar to clean out.

    Luckily I have well water…probably some of the cleanest water on Earth…I’ve tested it several times with kits.

    These fucking clickbait titles.

    It only really works with hard water, otherwise you’d have to add calcium to the water before boiling it, and they only tested it with something like 3 different plastics, and they’re the most benign and least reactive ones.

    This is not a magical solution to clean any water you boil.

      I was about to say. The headline sounds like the equivalent of removing mud from water by boiling it.

      Removing fine particles by aggregating them isn’t a brand new concept either, for what it’s worth.

      Could instead reverse osmosis remove those particles and be used as consumer products?

        Yes to the first, as for the second, who knows, but most likely not, as it’ll be mixed plastics and you can’t just mix them all together and make something out of them

    Microplastics are tiny pieces of plastic debris measuring less than 0.2 inches (5 millimeters) long,

    That can’t be right. There sure ain’t 5mm pieces of plastic in my drinking water. 0.05mm would be hard to believe.

      Not sure that’s correct, but 5 mm being the upper cap doesn’t mean they’re that long.

        I guess the author has just googled “define microplastics”… but when we think about microplastics in our drinking water we’re not thinking about 5mm pieces of plastic.

        A consumer grade filter will remove things larger than 0.0005mm.

      Sadly, that is the definition of microplastics. I’m not sure why a 5mm piece is considered „micro“

    There’s going to be some people that are going to start boiling all of their water after reading this article
