Does Perrier Have Microplastics? What the Filter Scandal Does and Doesn’t Show

Has Perrier been tested for microplastics?

Once, as far as we could find, and only lightly. In July 2022 the French group Agir pour l’Environnement published a survey of nine bottled waters analysed by Labocéa, a public water-testing laboratory in Brittany. The lab bought the bottles itself, washed their outsides, and filtered the whole volume of each. Particles were identified by infrared spectroscopy (FTIR) with a quantification limit of 10 µm.

The Perrier sample was a 1-litre “bouteille bleue” PET bottle listed as 25% recycled PET, with a polyethylene cap. The lab found 2 particles: one PET and one polyurethane. Across the nine waters, results ran from 0 to 121 particles per litre, the highest being a children’s bottle with a sports cap.

Keep the limits beside that number. It was one bottle per product, with no repeat. Anything under 10 µm was invisible to the method, and that is where most particles in bottled water are found by newer techniques. The NGO itself wrote that the survey “n’a pas de visée scientifique” (has no scientific aim). Glass Perrier and canned Perrier were not tested. Our explainer on why water tests miss small microplastics covers why a low count at 10 µm can coexist with many smaller particles.

Perrier is not one of the 11 brands in the 2018 Mason study, which did include Nestlé’s S.Pellegrino. France’s food safety agency ANSES published a 2025 study of drinks sold in France, but its press release names no brands. Nestlé says it runs its own quality testing; it has not published a Perrier particle count that we could find. So the honest answer is: lightly tested, small numbers in that one test, and not enough to rank Perrier against other waters. Our bottled water brands ranked page explains why brand tables built from different methods mislead.

What happened with Perrier’s filters?

French rules, following a 2009 EU directive, say a “natural mineral water” must be pure at source and cannot be disinfected. Since 2001 authorities have tolerated filtration down to 0.8 µm, a cut-off meant to avoid changing the water’s natural microbial makeup. The French Senate’s inquiry, which adopted its report on 14 May 2025, set out what Nestlé Waters did at its Vosges and Gard plants, including Perrier’s at Vergèze.

The Senate’s summary is blunt. It calls the State’s response “tardive, inadaptée et non transparente” (late, unsuitable and not transparent) and describes a deliberate strategy of concealment. It also records that some bacteriological contaminations at the Perrier site from June 2020 were not reported to the regional health agency, and that experts appointed by the prefect doubted the original purity of the Perrier aquifer at many boreholes. Nestlé’s position, on its own site, is that “the food safety of Perrier natural mineral waters has always been guaranteed.” Since 2022, water from two Vergèze boreholes has been sold as “Maison Perrier”, without the natural mineral water label, according to Swiss news agency Keystone-SDA.

The latest decision we could confirm is the prefect’s December 2025 order. According to franceinfo, it acknowledges occasional exceedances of bacteriological limits in raw water and adds virus monitoring not usually required for mineral water. A Paris criminal investigation remains open. We found no court ruling on the merits as of October 18, 2026.

Was Perrier contaminated?

Yes, but with microbes, not plastic, and mostly in raw water before treatment. That distinction is the main thing to take from the affair. The contamination findings were bacteriological: fecal-indicator bacteria in March 2024, and bacteriological exceedances in raw borehole water through 2025. ANSES recommended reinforced monitoring including viral risk in October 2023, according to the Senate. When it admitted the treatments in 2021, Nestlé argued, in the Senate’s words “sans preuve” (without proof), that they had not affected food safety or the water’s composition.

None of these documents measured microplastics, and none alleged that Perrier’s plastic content changed. The Senate report does discuss microplastics, but generally. It cites the 2024 Columbia study’s roughly 240,000 particles per litre in bottled water (three unnamed US brands) and recommends prioritising research. That is a call for research, not a finding about Perrier.

Does a 0.2 µm filter remove microplastics?

It can retain some particles at the point where it sits. That is all it can claim. Microplastics run from 5 mm down to about 1 µm, and nanoplastics are smaller. A membrane rated at 0.2 µm should hold back many particles larger than its rating in the water flowing through it. But three things stop anyone turning that into a claim about the bottle you drink:

• Position. The filters sat upstream of filling. Particles added later by bottle walls, caps, lubricants and filling equipment pass no filter at all. Several studies point to closures and handling as sources of what is found in bottled water.
• Ratings are not like-for-like. ANSES’s April 2026 note on microfiltration warns that filter ratings “are not directly equivalent to each other and may not accurately reflect the filtration capabilities” of the devices.
• Nobody measured it. We found no published before-and-after particle data for Perrier’s filters, at 0.2 or 0.45 µm. Nestlé has not claimed they reduce microplastics.

So the filter story cuts neither way. It doesn’t show that the finer filter made Perrier lower in plastic, and it doesn’t show that removing it added any. ANSES’s note lists the industry’s own reasons for microfiltration: removing particles naturally present in the source, protecting equipment and limiting contamination risk. Microplastics are not among them. For filters that do carry a tested microplastics claim, see water filters compared.

Is Perrier in glass better than plastic or cans?

Not reliably, on the evidence. Perrier comes in its green glass bottle, in PET and in cans; a 2013 trade report on Vergèze described separate glass, PET and can lines at the plant. Each format has a polymer contact point:

The glass result surprises people. In the ANSES study the glass wall shed nothing; the particles matched the paint on metal caps, scratched as caps rub together before bottling. Our Voss review sets out the three studies behind “glass is not automatically cleaner”, and do plastic bottle caps shed microplastics? covers the closure itself. Carbonation adds internal pressure, which is one reason our sparkling water guide treats fizzy water in PET as a format to handle with care.

For cans, the question shifts to the coating. See are cans lined with plastic? for what a can liner is and why “BPA-free” does not mean plastic-free.

Which Perrier do you actually buy?

Scan it. The app reads the format, the closure and how you store it, shows what has and hasn’t been tested for that brand, and suggests a lower-plastic way to drink sparkling water.

Does Perrier have PFAS?

PFAS are a separate question from microplastics, but they come up in the same searches. In 2020 Consumer Reports tested 47 bottled waters for PFAS. Perrier Natural Sparkling Mineral Water measured 1.1 parts per trillion of total PFAS, one of seven carbonated waters above 1 ppt; Topo Chico was highest at 9.76 ppt. Nestlé told CR its own recent testing did not detect PFAS. That was one round of testing six years ago. The Senate inquiry recommended PFAS testing campaigns for bottled water in 2025. Our PFAS explainer separates those chemicals from plastic particles.

What would a useful Perrier test look like?

The 2022 result is a start, not an answer. A test that could actually tell a Perrier drinker something would need to:

• Cover all three formats, glass, PET and can, bought at the same time, because the contact layers differ.
• Sample several lots and bottles, since single bottles in earlier studies ranged from near zero to thousands of particles within one brand.
• Count down to at least 1 µm and confirm each polymer spectroscopically, rather than relying on a dye.
• Report blanks so lab contamination is subtracted, and give counts with size ranges rather than one headline number.
• Test unopened and reopened bottles, because cap friction adds particles in other brands’ studies.

Nestlé has the samples and the laboratories to publish exactly this. Until someone does, any precise “Perrier microplastics per litre” figure you see online is either this one bottle or borrowed from another study.

What the evidence does not establish

• A Perrier particle count. One bottle at 10 µm and above is not a brand average, and says nothing about smaller particles, glass or cans.
• That the filters affected plastic either way. No before-and-after particle data were published.
• That Perrier is unsafe. A Nanterre court rejected UFC-Que Choisir’s emergency request to pull Perrier in November 2025, and the main contamination findings concerned raw water. The regulatory and criminal questions are still open.
• A health effect from the particles. The FDA says current scientific evidence does not show that the levels of micro- and nanoplastics detected in foods pose a risk to human health. Research continues.
• The cap and can coatings. Perrier’s site blocked our access, and we found no first-party statement on its closure materials or can liner. We have not guessed.

What should you drink instead if this worries you?

1. If you like Perrier, keep it and handle it well. Store it cool and out of sunlight, finish a PET bottle quickly rather than reopening it all day, and don’t refill it. Heat raised particle release in bottled-water handling studies.
2. Choose a format for your reasons. Glass avoids a PET wall but not a closure; a can avoids PET but adds a coating. Neither has a published Perrier particle count.
3. Make sparkling water at home from tap water through a filter certified to NSF/ANSI 401 for microplastics, carbonated in a glass carafe rather than the default plastic bottle.
4. If the affair itself bothers you, that is a question of labeling and trust, not microplastics. Read the label: Perrier carries “natural mineral water”; Maison Perrier does not.
