You're probably on this page because:
- You read about microplastics and can't stop thinking about it
- You switched to bottled water to avoid them
Bottled water isn't the answer. A certified filter is.
Microplastics, by the numbers
- Bottled water has also been found to contain microplastics in research.
- NSF/ANSI 401 is one standard that includes microplastics reduction claims.
Sources: [Cite a specific study]; NSF.
How they get into water
From breaking-down plastic in the environment, and from plastic pipes and packaging.
What catches them
- Reverse osmosis: the membrane blocks particles far smaller than microplastics
- Certified carbon block filters: some are certified for microplastics
- Pitchers: only if certified

Our take
Don't trade one plastic for another
Working directly with our manufacturers, and holding our own patents, has taught us exactly where filters succeed and fail.
A lot of people switch to bottled water to avoid microplastics, but bottled water has been found to contain them too. The fix is filtering your own tap with a certified system.
Check the certification for the specific claim. "Removes microplastics" on a box means nothing without a test standard behind it.
