    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.
