Is it safe to use plastic pitcher water filters?
Based on 2 peer-reviewed studieskitchen
Verdict: Use Caution
The filter helps, but the plastic pitcher leaks microplastics into the filtered water.
What's actually in it
Brita, PUR, and similar plastic pitcher filters have a carbon filter that removes chlorine and some contaminants. Then the filtered water sits in a plastic pitcher for hours or days, picking up microplastics.
What the research says
A 2025 study in NPJ Clean Water showed carbon filters remove most microplastics from water. But the pitcher itself adds them back. A 2025 study found microplastics across plastic water containers.
Upgrade to a glass pitcher filter (Soma, Aarke) or a stainless steel reverse osmosis countertop unit. Or filter at the tap with a metal-body filter and pour into a glass carafe.
