If you’re on a crusade to banish microplastics, the refrigerator filter is not your champion. You need the heavy artillery: Reverse osmosis (RO) systems. These are the nuclear submarines of water filtration. They shove water through a membrane so tight, only pure H2O molecules get through. Even dissolved salts and viruses bounce off.
Do Activated Carbon Filters Remove Microplastics? - Tongke
Reverse osmosis is great at zapping microplastics, but it’s also expensive, wastes water (typically 3-4 gallons wasted per gallon purified), and requires installation. It’s the overachieving cousin at the family reunion. For most people, a standard fridge filter is like having a friendly, slightly lazy dog that barks at mailmen but ignores burglars.
Another option: distillation. Boil water, catch the steam, and you get pure water. Microplastics have a higher boiling point than water, so they stay in the pot. It works, but it’s slow and uses a lot of energy. You are basically playing kitchen chemist for every glass.
