Fiji vs Evian
Which premium bottled water has fewer microplastics?
The verdict
Neither, meaningfully — and the difference in their scores is mostly a difference in how much anyone has looked. Evian was in the eleven-brand Mason 2018 cohort and Fiji was not. Both are water in a PET bottle, and that is the finding.
PET (#1) bottle with a polypropylene cap; a glass line also exists
87% confidence
These carry different evidence grades. Fiji Water is grade B and Evian is grade A. One component of our score is measured release, which only earns points where a laboratory has actually counted particles — so a product nobody has tested scores lower than an identical one that has been. Part of the gap you are looking at is a difference in how much anyone has looked. Why we do it this way →
Where they actually differ
| Fiji Water | Evian | |
|---|---|---|
| Evidence grade | B — no brand-specific test exists | A — brand was in a tested cohort |
| Bottle | PET with a polypropylene cap | PET with a polypropylene cap; a glass line also exists |
| Supply chain | Long, tropical, ambient | Long, temperate |
| The real decision | Neither, if a glass option is on the shelf | Buy the glass Evian, which is the same water |
Where this comparison stops being reliable
This is a comparison across evidence grades and it is the clearest example of why we publish confidence separately. Fiji scores lower than Evian, and no part of that gap is a claim that Fiji is cleaner — it is a claim that nobody has checked.
The full picture on each
Does Fiji Water have microplastics?
Almost certainly yes, like all PET bottled water — but no one has published a test of Fiji specifically. The bottle is the same PET measured at roughly 240,000 particles per litre across other brands, and Fiji ships further and warmer than most.

Does Evian have microplastics?
Yes in the plastic bottle, which was one of the eleven brands measured in Mason 2018. Evian also sells the same water in glass, and that is a genuinely different product for this purpose — the format changes the answer, the spring does not.
