Best Water to Drink in 2026: Types, Brands, and What Actually Matters

What Is the Best Water to Drink? A No-Nonsense Guide

Walk into any grocery store and you'll find 30+ different bottled water brands staring back at you. Fiji. Evian. Voss. Smartwater (or Smart Water, depending on who you ask). Dasani. Poland Spring. Arrowhead. Some cost $1, others cost $8. Some claim to be "naturally alkaline." Others brag about volcanic filtration or glacial water sourced from ancient ice.

So what is the best water to drink? The honest answer: it depends on what you're optimizing for. Taste, mineral content, pH level, price, and environmental impact all pull in different directions. We tested and researched the most popular bottled water brands to help you pick the right one.

The 7 Types of Drinking Water, Ranked by Health Benefits

Before comparing brands, you need to understand what's actually in the bottle. Not all water is the same, and the type matters more than the label.

1. Spring Water

Spring water comes from an underground source and flows naturally to the surface. It retains natural minerals like calcium, magnesium, and bicarbonate picked up as it filters through rock layers. Brands like Poland Spring, Evian, and Crystal Geyser sell spring water.

The mineral content varies by source. Evian contains about 309 mg/L of total dissolved solids. Crystal Geyser runs around 130 mg/L. That difference affects taste and minerality noticeably.

Spring water is a solid everyday choice. It tastes better than purified water to most people because the minerals add subtle flavor. The FDA requires it to come from an actual spring, so the sourcing is regulated.

2. Mineral Water

Mineral water must contain at least 250 parts per million of total dissolved solids from a geologically protected underground source. Think of it as spring water's richer cousin. San Pellegrino (1,109 mg/L TDS) and Gerolsteiner (2,527 mg/L TDS) are classic examples.

The high mineral content means you're getting calcium, magnesium, and bicarbonate with every sip. A 2017 study in the Journal of the International Society of Sports Medicine found that mineral-rich water improved hydration markers compared to low-mineral water during exercise.

Downside? Mineral water costs more. And some people find the strong minerality off-putting, especially with high-TDS brands like Gerolsteiner.

3. Purified Water

Purified water starts as tap water, then gets filtered through reverse osmosis, distillation, or deionization to remove contaminants. Dasani and Aquafina are purified water. So is most of the water from your home reverse osmosis system.

The process to purify tap water strips out both bad stuff (chlorine, lead, fluoride, bacteria) and good stuff (minerals). That's why purified water often tastes flat or "empty" — most people say spring water tastes better in blind tasting bottled water comparisons. Some brands add electrolytes back in for taste. Smartwater adds calcium chloride, magnesium chloride, and potassium bicarbonate.

Purified water is the safest option if you're worried about contaminants. But it's not necessarily the healthiest, since you lose the natural minerals.

4. Alkaline Water

Alkaline water has a pH level above 7, typically between 8 and 9.5. Some brands achieve this naturally (the water passes through mineral-rich rock), while others ionize regular water to raise the pH artificially.

Naturally alkaline spring water brands include Icelandic Glacial (pH 8.4), Waiakea (pH 8.2), and Essentia (pH 9.5, though Essentia is ionized, not naturally alkaline). Voss Water also offers an alkaline option. The alkaline drinking water market has exploded in the last decade, with consumers debating whether water is best when it's acidic or alkaline.

Does high pH water actually help? The evidence is mixed. A 2012 study in Annals of Otology, Rhinology & Laryngology found that water with pH 8.8 deactivated pepsin, potentially helping acid reflux. But the American Institute for Cancer Research says there's no evidence alkaline water prevents cancer or other diseases.

Our take: naturally alkaline water from a spring source is fine. Paying a premium for ionized water with artificially raised pH is probably not worth it. Want to try it yourself? See our guide on how to make alkaline water at home, or browse our picks for the best alkaline water brands.

5. Distilled Water

Distilled water has been boiled into steam and condensed back into liquid. This distillation process removes virtually everything: minerals, bacteria, chemicals, dissolved solids. The result is water in its purest form.

Distilled water is useful for medical equipment, car batteries, and steam irons. For drinking? It's safe but not ideal. The lack of minerals means it can taste flat, and long-term consumption without mineral supplementation could theoretically contribute to mineral deficiencies, though this is debated.

6. Sparkling Water

Sparkling water contains dissolved carbon dioxide, either naturally occurring (Perrier, San Pellegrino) or added (Topo Chico, LaCroix). It's available in glass bottle and plastic formats. The carbonation doesn't affect hydration. A 2016 study in the American Journal of Clinical Nutrition confirmed that sparkling water hydrates just as well as still water.

Some people worry about sparkling water damaging tooth enamel. The acidity is higher than still water (pH around 3-4), but a 2001 study in the Journal of Oral Rehabilitation found that sparkling mineral water was only slightly more erosive than still water and far less erosive than soft drinks.

7. Flavored and Enhanced Water

Flavored water and enhanced water brands like Hint, Propel, and Vitaminwater add fruit flavors, vitamins, or electrolytes. Check the label carefully. Some "enhanced" waters contain as much sugar as soda. Vitaminwater, for example, has 26 grams of sugar per bottle.

If you want flavor without sugar, Hint Water uses fruit essences with zero calories and zero sweeteners. It's a decent option for people who struggle to drink plain water.

Best Bottled Water Brands: Our Picks for 2026

After comparing mineral content, pH levels, taste, sourcing, and price across 20+ brands, here are our top picks by category.

Fiji vs. Evian vs. Smartwater: How the Big Brands Compare

These three dominate the premium bottled water market. Here's how they stack up:

Fiji wins on taste for most people. The high silica content gives it a distinctly soft mouthfeel that other brands can't match. Evian wins on mineral balance. Smartwater wins on price and availability but loses on mineral content since it starts as tap water.

Is Tap Water Safe to Drink?

In most U.S. cities, yes. The EPA regulates public water supplies under the Safe Drinking Water Act, testing for 90+ contaminants. Municipal tap water in cities like New York, Boston, and Portland consistently ranks among the cleanest in the country.

But "most cities" isn't "all cities." The Flint, Michigan water crisis (2014-2019) exposed lead contamination affecting 100,000+ residents. A 2023 USGS study found PFAS ("forever chemicals") in 45% of U.S. tap water samples. Older homes with lead pipes face ongoing risks.

If you're concerned about tap water quality, a home filtration system is more cost-effective than bottled water. A reverse osmosis water system removes 95-99% of contaminants. Even a basic carbon filtration pitcher removes chlorine, lead, and many common contaminants. Where your water comes from matters, and knowing your local water supply is the first step.

The water quality in your specific area matters. Check your local Consumer Confidence Report (every water utility publishes one annually) or test your tap water independently through a certified lab.

Spring Water vs. Purified Water: Which Is Better?

This is the most common question in the bottled water aisle, and the answer isn't straightforward.

Spring water retains natural minerals from its underground source. Those minerals (calcium, magnesium, potassium) contribute to daily intake and affect taste. Spring water generally tastes better in blind taste tests because the minerals add complexity.

Purified water has been stripped of contaminants AND minerals through reverse osmosis or distillation. It's the safest option if the source water is questionable, but it tastes flat to most people. Some brands add minerals back for taste.

For everyday drinking, spring water from a reputable brand is the better choice. For people with compromised immune systems or in areas with poor water supply, purified water provides an extra safety margin.

Does pH Level Actually Matter?

The alkaline water industry wants you to think so. They claim that drinking water with a high pH (8-10) can neutralize acid in your body, boost energy, and prevent disease.

Reality check: your body maintains blood pH between 7.35 and 7.45 regardless of what you drink. Your kidneys and lungs handle pH regulation. Drinking alkaline water doesn't meaningfully change your blood pH.

That said, naturally alkaline water isn't harmful. If you prefer the taste of Icelandic Glacial or Waiakea, drink it. Just don't pay a premium expecting health miracles. The Environmental Protection Agency recommends drinking water with a pH between 6.5 and 8.5, and most bottled water falls within that range.

How Much Water Should You Actually Drink?

The "8 glasses a day" rule is a myth with no scientific basis. The National Academies of Sciences recommends about 3.7 liters (125 oz) daily for men and 2.7 liters (91 oz) for women, but that includes water from food (which accounts for about 20% of intake).

A simpler approach: drink when you're thirsty. Your body's thirst mechanism works. If your urine is pale yellow, you're hydrated. If it's dark, drink more. Athletes, people in hot climates, and pregnant women need more than average.

The type of water matters less than the amount. Whether you're drinking tap water, spring water, or purified water, consistent hydration is what keeps your body functioning properly.

Frequently Asked Questions

What is the healthiest water to drink?

Natural spring water or mineral water with a balanced mineral content is generally the healthiest choice for daily drinking. Brands like Evian, Fiji, and Crystal Geyser provide natural minerals (calcium, magnesium, bicarbonate) without artificial additives. The key is choosing water that's free of contaminants and provides trace minerals your body needs.

Is bottled water better than tap water?

Not necessarily. In most U.S. cities, tap water meets or exceeds EPA safety standards and is perfectly safe to drink. Bottled water is regulated by the FDA, which has similar but not identical standards. The main advantages of bottled water are convenience and consistency, not safety. If your local tap water quality is good, a reusable bottle with filtered tap water is the most cost-effective and environmentally friendly option.

What is the best bottled water brand?

For overall quality and taste, Evian and Fiji consistently rank highest in taste tests and mineral analysis. For budget-conscious buyers, Crystal Geyser and Kirkland (Costco) offer excellent quality at lower prices. The best brand depends on whether you prioritize taste, mineral content, pH level, or price.

Is alkaline water worth it?

Naturally alkaline water (like Icelandic Glacial or Waiakea) is fine to drink but unlikely to provide the dramatic health benefits some brands claim. Your body regulates its own pH regardless of what you drink. If you enjoy the taste, go for it. But don't pay a premium expecting it to cure diseases or dramatically improve your health.

What is the difference between distilled water and purified water?

Both have impurities removed, but through different processes. Distilled water is boiled into steam and condensed, removing virtually everything. Purified water typically uses reverse osmosis or carbon filtration, which may leave trace minerals. Purified water is better for daily drinking; distilled water is better for medical equipment and appliances.

Is sparkling water as hydrating as still water?

Yes. Multiple studies confirm that sparkling water hydrates just as effectively as still water. The carbonation doesn't affect absorption. The only concern is that the slightly acidic pH (3-4) could theoretically affect tooth enamel with excessive consumption, but research shows the effect is minimal compared to soft drinks or fruit juice.

How can I test my tap water quality?

Request your local utility's annual Consumer Confidence Report (required by law). For more detailed testing, send a sample to a certified lab through the EPA's Safe Drinking Water Hotline (800-426-4791). Home test kits from brands like Tap Score provide detailed analysis for $100-200.
