 28 Popular Bottled Water Brands, Ranked Worst To Besthttps://www.tastingtable.com/756881/popular-bottled-water-brands-ranked-worst-to-best/ | 2.0% |
There isn’t one universally agreed “cleanest” spring water brand, because “clean” can mean different things: lowest contaminants, best source protection, least processing, mineral profile, or safest packaging. Independent testing also shows that bottled water quality can vary by brand and even by source within a brand.
For high-quality natural spring waters, these are often considered among the better choices:
| Brand | Why it stands out |
|---|---|
| Icelandic Glacial | Very low mineral content, naturally filtered through Icelandic lava, and often chosen by people seeking a very “pure” taste. Some testing of glass-bottled waters has found very low detectable heavy metals. abnrf.org |
| Mountain Valley Spring Water | Long-established spring source, available in glass bottles, and a good option if you prioritize avoiding plastic contact. Glass-bottle testing has shown very low detectable heavy metals. abnrf.org |
| Evian | Protected Alpine spring source with a consistent mineral profile; more mineral-rich than some “pure” waters. |
| Fiji Water | Artesian source and distinctive mineral profile; generally well regarded for taste, though it is not a spring water in the strict U.S. labeling sense. |
| Saratoga Spring Water | A premium spring water available in glass bottles; glass packaging is appealing if minimizing plastic exposure is a priority. abnrf.org |
My short list for clean + natural + premium would be:
A few things to keep in mind:
If you mean the healthiest water for daily drinking, I’d rank it slightly differently than “cleanest” (minerals, electrolytes, and fluoride content start to matter).
When looking for the "cleanest" natural spring water, "clean" usually refers to a combination of low Total Dissolved Solids (TDS/mineral load), a lack of chemical and microplastic contaminants, and pristine source protection . Unlike purified tap waters (like Aquafina or Dasani), true spring water retains its natural minerals, but the concentration and purity vary wildly by source geography and bottling practices.
The top-tier natural spring water brands frequently cited for exceptional purity, minimal contamination, and transparent third-party testing include:
If you'd like, let me know:
If by “cleanest” you mean a genuinely natural spring source, low contaminants, minimal processing, and preferably glass packaging, my top pick is Icelandic Glacial.
$2.98
Icelandic Glacial — best overall for purity
Mountain Valley Spring Water — best U.S. choice
$25.98
$76.00
One important caveat: there isn't a single universally accepted “cleanest water” ranking. Bottled-water quality can vary by source, bottling facility, bottle material, and contaminants tested. Older EWG investigations also found that transparency about sources and treatment varies considerably among brands.
If I were buying specifically for maximum purity: Icelandic Glacial in glass.
If I wanted the best U.S.-sourced option: Mountain Valley in glass.
If you want, I can also rank the top 10 bottled waters specifically by PFAS, microplastics, heavy metals, and other contaminants and tell you which one is healthiest overall.
When people talk about the "cleanest" natural spring water, they are usually looking for a combination of low total dissolved solids (TDS), non-detectable or ultra-low chemical and heavy metal contaminants, a pristine isolated source, and packaging that doesn't leach plastics.
While individual taste and local availability vary, independent water quality testing and independent purity reviews frequently point to a few standout natural spring and aquifer brands:
Would you prefer to focus on spring waters that come exclusively in glass or aluminum packaging to avoid plastics, or are you looking for a specific mineral profile (like high alkalinity or low sodium)?
If by “cleanest” you mean natural spring water with very low contaminants, low mineral load, and strong independent testing, my top pick right now is Icelandic Glacial.
$2.98
$1.50
Mountain Valley is an excellent choice: it comes from a spring in the Ouachita Mountains and is bottled at the source in glass. It has more naturally occurring minerals than Icelandic Glacial, so it tastes richer.
$13.52
Evian is legitimate natural spring water from the French Alps, naturally filtered through underground rock for more than 15 years. www.evian.com But if purity/microplastics is your primary concern, I'd put Icelandic Glacial ahead of it; one 2026 third-party screening found particles consistent with PET microplastics in a plastic-bottled Evian sample.
My ranking for “cleanest”:
If you tell me whether you care most about PFAS, microplastics, heavy metals, fluoride, or overall purity, I can rank the top 5 specifically on that criterion.
There isn't a single brand that can be definitively called the "cleanest" natural spring water, because water quality varies by source, bottling batch, and what you mean by "clean" (PFAS, heavy metals, bacteria, microplastics, etc.). However, based on independent testing and transparency, a few brands consistently stand out.
If I had to recommend one overall, it would be:
$1.50
Why it's often ranked at the top:
Other excellent choices include:
$2.88
Known for a protected Icelandic source, naturally low mineral content, and consistently good contaminant testing.
$2.78
Naturally filtered through volcanic rock and contains silica and other naturally occurring minerals. Availability varies by region.
Some well-known spring waters have had issues reported in recent years:
Natural spring water always contains some naturally occurring minerals, which is part of its appeal. If your priority is minimizing contaminants rather than drinking spring water specifically:
If you're specifically concerned about PFAS, microplastics, heavy metals, or you're looking for the best-tasting spring water, I can narrow the recommendations based on that priority.
When looking for the "cleanest" natural spring water, purity depends on a combination of source protection (distance from industrial/agricultural pollution), low Total Dissolved Solids (TDS), absence of contaminants (like PFAS or heavy metals in independent lab tests), and the type of packaging (glass or aluminum vs. plastic, which can leach microplastics).
Based on independent water quality tests, sourcing integrity, and consumer/sommelier consensus, a few standout brands are widely considered to offer the cleanest natural spring water:
Note: Brands like Dasani or Smartwater are often marketed heavily for crispness, but they are technically purified municipal/distilled water with added minerals rather than natural spring water.
If you're narrowing down your choice, let me know:
There isn't a single brand that can objectively be called the "cleanest" natural spring water. It depends on what you mean by clean:
Based on independent testing and publicly available water quality reports, these are among the strongest options:
$1.50
This is frequently recommended because:
Other excellent choices include:
$2.98
$6.70
One thing to keep in mind: studies have found that most bottled waters—regardless of brand—can contain some microplastics, largely because of the bottle or cap rather than the water source itself. If minimizing microplastics is your priority, choosing glass bottles is generally a better option.
If your goal is the cleanest bottled spring water overall, my ranking would be:
If you're looking for the lowest PFAS, lowest microplastics, or the best tasting option specifically, I can narrow the recommendation further.
When looking for the "cleanest" natural spring water, purity is usually judged by a combination of low contaminant levels (like non-detectable PFAS, heavy metals, and chemicals), low Total Dissolved Solids (TDS) , and environmentally protective glass or aluminum packaging that prevents plastic leaching.
Independent lab tests and consumer advocacy groups (such as Consumer Reports ) consistently point to several top-tier natural spring water brands known for exceptional source protection and purity:
Note: If absolute chemical absence is your primary goal, purified waters (like reverse-osmosis brands) are technically stripped of all minerals and impurities, but true natural spring water retains natural electrolytes while maintaining strict non-detectable contaminant lab results.
If you're looking for a specific type of water, would you prefer recommendations based on low sodium/minerals, alkaline pH levels , or glass/plastic-free packaging?
Several brands are recognized for offering exceptionally clean natural spring water, often lauded for their purity, natural filtration processes, and sustainable sourcing. Top contenders based on consumer reviews and expert rankings include:
Key Considerations for Cleanliness:
Would you prefer to know about bottled in glass options only, or are you looking for the best value in recycled plastic/aluminum?
