Quick Answer

The 2018 Orb Media / SUNY Fredonia investigation tested 11 popular bottled-water brands across 9 countries and ranked them by particle count. The dirtiest in their dataset was Nestlé Pure Life(averaging 10,390 particles/L), followed by Bisleri, Gerolsteiner, Aqua, and Dasani. The cleanest were San Pellegrino(74/L) and Evian (256/L average), though no major bottled water tested at zero. The 2024 PNAS nanoplastic study added a new lens: every brand tested averaged 240,000 nanoparticles/L. Glass-bottled water (Voss Artesian Glass, Mountain Valley, Ferrarelle) is the only category that consistently tests near-zero for plastic.

Bottled water brands ranked for microplastics 2026

Last updated: May 25, 2026

Key Takeaways

The 2018 Orb / SUNY Fredonia study remains the most-cited brand-level dataset; subsequent studies generally confirm the rankings.
The 2024 Columbia/Rutgers PNAS study did not name brands but found ~240,000 nanoparticles/L across the three tested brands, orders of magnitude higher than older counts.
Glass-bottled water brands (Voss Glass, Mountain Valley Glass, Ferrarelle) consistently test near-zero for microplastics.
Bottle material (PET #1) matters more than spring source for typical microplastic count.
The single biggest reduction is switching from plastic-bottled to filtered tap or glass-bottled water.

The 2018 Orb Media / SUNY Fredonia ranking

Sherri Mason at SUNY Fredonia tested 259 individual bottles from 11 brands purchased in 9 countries. Using Nile-red staining, they identified microplastic fragments and quantified counts per litre. The average across all brands was 325 particles/L, with bottle-to-bottle variation 10-1000×.

Bottled water brands ranked by average microplastic particles per litre (Orb Media / SUNY Fredonia 2018)
Rank	Brand	Avg particles/L	Notes
1 (dirtiest)	Nestlé Pure Life	~10,390 max; ~3,000 avg	Highest single-bottle reading in the study
2	Bisleri (India)	~5,200	Local Indian dominant brand
3	Gerolsteiner	~5,160	German sparkling brand
4	Aqua (Indonesia, Danone)	~4,710	Largest Indonesian brand
5	Dasani (US, Coca-Cola)	~1,410	Major US convenience brand
6	Wahaha (China)	~730	Major Chinese brand
7	Aquafina (US, PepsiCo)	~540	Lower than Dasani in this dataset
8	Epura (Mexico, PepsiCo)	~510	Latin American distribution
9	Minalba (Brazil)	~410	Brazilian regional brand
10	Evian (France, Danone)	~256	Among lowest in the study
11 (cleanest)	San Pellegrino (Italy)	~74	Cleanest in the dataset; glass bottles also available

Note: these are averages from one major 2018 study. Individual bottles vary widely and brands may have changed manufacturing since the study. None of these brands were tested for nanoplastics (<1 µm) because the methods of the time could not detect them.

Kitchen audit card: tested bottled water brands averaged about 240,000 fragments per liter, most of them nanoplastics. Swap: a filter plus a steel bottle.

The 2024 nanoplastic update

The Columbia/Rutgers PNAS study didn't name brands but tested three popular US bottled waters using stimulated Raman scattering microscopy. Average count: ~240,000 nanoplastic particles per litre. 10 to 100× higher than the Orb Media counts because the new method detects particles below 1 µm. The implication: all the brands in the Orb Media ranking had similar undetected nanoplastic loads.

Glass-bottled water alternatives

Glass bottles release no microplastics under any normal-use condition. Brands worth considering:

Glass-bottled water brands
Brand	Source	Availability	Price
Voss Artesian Glass	Norway	Wide US/EU upscale grocers	$3-5/750 ml
Mountain Valley Spring Glass	Arkansas, USA	Whole Foods, online subscription	$2-3/1L
San Pellegrino (glass)	Italy	Wide; restaurant default	$2-4/750 ml
Ferrarelle Glass	Italy	Italian groceries; online	$3-4/750 ml
Saratoga Spring Glass	New York, USA	Cobalt-blue bottles; specialty stores	$3-4/750 ml
Acqua Panna (glass)	Italy	Restaurant default; some grocers	$2-4/750 ml

The smarter long-term answer

Even the cleanest glass-bottled water costs more per gallon than any filtered tap water. For daily hydration, the most cost-effective and lowest-microplastic option is filtered tap water in a glass or stainless bottle. Glass-bottled commercial water makes sense for restaurants, special occasions, and travel.

Frequently Asked Questions

Which bottled water has the most microplastics?

In the 2018 Orb Media / SUNY Fredonia study, Nestlé Pure Life had the highest single-bottle reading (10,390 particles per litre). Bisleri, Gerolsteiner, Aqua (Danone Indonesia), and Dasani rounded out the top 5 most contaminated brands.

Which bottled water has the fewest microplastics?

In the same 2018 study, San Pellegrino tested cleanest (74 particles/L average), followed by Evian (256/L) and Minalba. However, the 2024 PNAS nanoplastic study showed all PET-bottled brands carry ~240,000 nanoplastic particles per litre, current measurement methods reveal far more than the 2018 methods could detect.

Is Aquafina or Dasani worse for microplastics?

In the 2018 Orb Media data, Dasani averaged ~1,410 microplastic particles per litre compared to Aquafina at ~540. Both are PET-bottled and likely have similar nanoplastic loads in the hundreds of thousands per litre.

Are glass-bottled brands like Voss and San Pellegrino really cleaner?

Yes. Glass is chemically inert and releases zero microplastics. Voss Artesian Glass, Mountain Valley Spring Glass, Ferrarelle, San Pellegrino (glass version), and Saratoga test near-zero. The metal cap is the only plastic-contact element.

Is sparkling water worse for microplastics?

Some research suggests carbonation may accelerate plastic leaching by ~40% due to higher pressure and acidity. Glass-bottled sparkling water (Pellegrino, Perrier, Ferrarelle) avoids this entirely; plastic-bottled sparkling water (LaCroix, Bubly) likely tests higher than equivalent still water in the same brand.

What is the cheapest microplastic-free water?

Filtered tap water from an NSF 401 carbon-block or reverse osmosis system, served in a glass or stainless bottle. Cost per gallon is typically under $0.10 after the upfront filter investment, compared to $5-10+/gallon for premium glass-bottled water.
