Best Alkaline Waters

Verywell / Chloe Jeong

On the pH scale of 0 to 14, pure water is a neutral 7, meaning that it's neither acidic nor alkaline. Alkaline water has a higher pH and is thought to promote alkalinity in the body and hydrate more efficiently than regular water. However, these health claims are supported by limited research.

That said, drinking more water— whether it is alkaline or not— will likely benefit your health and promote optimal hydration. If you prefer the taste of alkaline water and feel better drinking it, then that's a plus. There are many options on the market for incorporating alkaline water into your lifestyle, including bottled alkaline water, reusable bottles with alkaline filters, alkaline pitchers, and even home alkaline filtration systems.

Here, the best alkaline waters:

Best Overall: Essentia Ionized Alkaline 9.5 PH Water

Essentia Ionized Alkaline 9.5 PH Water

With a pH of 9.5, silky-smooth taste, and extra electrolytes, Essentia Water takes the top pick for alkaline waters. It's also the only premium bottled water that is listed in the Physicians’ Desk Reference and is clinically shown to hydrate better than regular tap water. That said, the clinical study was funded by Essentia Water, so there may be a conflict of interest.

Unlike some alkaline waters that are treated with harsh chemicals, Essentia is purified through a proprietary microfiltration process and reverse osmosis. The water goes through a three-part ionization process in which the water is purified, trace amounts of electrolytes are added, and then bitter-tasting ions are removed. The added electrolytes —bicarbonate, potassium, magnesium, and calcium— add to the clean, smooth taste.

Best with Eco-Friendly Packaging: Flow Alkaline Spring Water

Flow Alkaline Spring Water

If you're looking for alkaline water with a low carbon footprint, Flow Alkaline Spring Water is the top choice. The eco-friendly packaging is made from 68 percent renewable and 100 percent recyclable materials. Most water bottles are plastic; however, Flow packaging is made primarily from paper by Tetra Pak using sustainably sourced fibers and a plant-based cap.

Choosing Flow is good for the planet and your body. The 100% natural spring water is sourced from the family-owned spring in Ontario, Canada, and from Seawright Springs in Virginia. It has a pH of 8.1. The naturally occurring minerals—magnesium, calcium, bicarbonate, and potassium—boost hydration and taste.

An added bonus: if you're looking for a flavored alkaline water, Flow also has you covered. The water comes in Cucumber + Mint, Lemon + Ginger, Blackberry + Hibiscus, Strawberry + Rose, Watermelon + Lime, and Grapefruit + Elderberry.

Best Antioxidant-Infused: Bai Antioxidant Water

Bai Antioxidant Water

Super purified using reverse osmosis technology, Bai Antioxidant Water is a superior alkaline water that is pH balanced to 7.5 or higher. Electrolytes including potassium and magnesium help to boost hydration and contribute a clean, crisp taste.

Bai Antioxidant Water is not only pH balanced and electrolyte enhanced, it's also infused with selenium. Each 8-ounce serving contains 10% of the recommended daily value of selenium, a natural antioxidant that may play a role in the prevention of cancer, cardiovascular disease, and cognitive decline.

Antioxidants like selenium work to reduce inflammation in the body by fighting free radicals. Reaching for Bai Antioxidant Water after a tough workout may help promote recovery, as research suggests that selenium supplementation may help to reduce exercise-induced oxidant stress.

Best Filtered: Core Hydration Nutrient Enhanced Water

Core Hydration Nutrient Enhanced Water

If you’re looking for a refreshing, filtered water taste that still packs all of the alkaline water benefits, CORE Hydration is an excellent choice. CORE is only slightly alkalized with a pH of 7.4, but you can still reap the potential benefits of alkalization. CORE filters its water to make sure you’re only drinking the nutrients you need, so you’ll never find a trace of fluoride, chromium, arsenic, or chlorine.

The versatile CORE bottle comes with a large cap that doubles as a cup for easy drinking. The large 30.4-ounce bottle can help you easily meet your hydration goals. The bottles are BPA-free and are 100% recyclable, so you know you’re making a responsible choice, even if they are single-use.

Best Budget: Phure Alkaline Water

Phure Alkaline Water

We know that purchasing specialty water can be expensive, especially as you can usually get regular tap water for free. Drinking alkaline water doesn't have to break the bank as there are budget-friendly options on the market like PhURE Alkaline Water.

Comparable to Essentia, PhURE boasts a 9.5 pH. It contains electrolytes including potassium and magnesium that contribute great taste and a hydration boost. The convenient 50.7 fluid ounce bottles are easy to take with you on the go, and the pack of 12 is great to stock up.

Best Pitcher: New Wave Enviro Enviro Alkaline Pitcher

New Wave Enviro Alkaline Pitcher

A refillable pitcher is an excellent, affordable way to enjoy fresh, filtered alkaline water at home. The BPA-free New Wave Enviro Alkaline Pitcher raises the pH of tap water to a range of 8.5 to 9.5 using a powerful filter. Each filter cartridge can alkalize and filter up to 300 liters (64 gallons) of water, which when compared with single-use water bottles, can conserve a ton of plastic and money. The filter even has a handy digital indicator that will remind you when you need to replace it.

The pitcher system uses activated carbon, ion exchange resins, negative potential particles, and far-infrared ceramic balls to effectively purify and enhance regular tap water. The sleek pitcher fits easily into your refrigerator and holds up to 3.5 liters of water. Since it's dishwasher-safe, the pitcher is a breeze to clean.

Best Machine: APEC Water Systems Alkaline Mineral Ph+ Ultra Safe Reverse Osmosis Filter System

APEC Alkaline Mineral Ph+ Ultra Safe Reverse Osmosis Drinking Water Filter System

While buying bottled alkaline water is a good temporary solution, buying plastic bottles for a long period of time is not only expensive, but also taxing on the environment. If you’re committed to drinking alkaline water, upgrade your home filtration system with this water filter system from APEC. Through a six-step process, this machine purifies your water to remove harmful substances and unpleasant tastes and then mineralizes your drinking water with calcium to increase the alkalinity.

While purchasing this system can feel like a big investment, it’ll be worth it in the long run both because you will save on buying individual-use bottles. Reviewers note that the system is designed for the average DIY homeowner, as it is easy to install and maintain.

Best Portable: GoFiltr Alkaline Water Filter

GoFiltr Alkaline Water Filter

If you’re looking for a simple way to enjoy alkaline water without extra plastic usage, a portable alkaline filter is a great choice. This reusable option from GoFiltr makes ionized alkaline water in any bottle, including most reusable water bottles, hydration packs, and water bladders with an opening of one inch or larger. The convenient, easy-to-carry filter is powerful enough to filter up to 40 ounces at once, and each filter lasts up to three months.

Simply place the filter inside your favorite water bottle and fill it with water. The high-quality filter uses all-natural, proprietary granules infused with magnesium, potassium, calcium, trace minerals, and electrolytes to turn tap water into alkaline water in about 15 minutes. The filter creates ionized antioxidant mineral alkaline water with a pH up to 9.5 and removes potentially harmful heavy metals.

Final Verdict

For an excellent bottled alkaline water, try Essentia (view at Amazon). For a more sustainable and budget-friendly option, consider purchasing a reusable pitcher like the New Wave Enviro Alkaline Pitcher Filter (view at Amazon).

What to Look for in Alkaline Water


You can reap the benefits of alkaline water in many different ways. The water is available in convenient single-use bottles, individual filtration bottles, refillable pitchers, or more complex home systems. Each option has unique pros and cons. Single-use bottles are more affordable on a short-term basis; however, reusable options or home systems may reduce cost and plastic use in the long run

Measure of Alkalinity (pH):

Alkaline waters come in a range of pH 8.5 to 9.5. Technically, alkaline water is any water whose pH measures above 7, but most waters on the market seem to fall somewhere in the range of 7 and 9. Note that there's no proven scientific research that identifies the optimal pH of alkaline water, nor is there consistent clinical evidence to support the purported health benefits of alkaline water.

Additional Ingredients:

Some bottled alkaline waters contain added ingredients, such as antioxidants or vitamins, which may impart beneficial effects. As with all packaged goods, it's a good idea to take a look at the ingredient list before selecting an item.

Frequently Asked Questions

  • What Is Alkaline Water?

    Technically, alkaline water is any water with a pH level above 7 on a scale of 0 to 14. The pH level indicates how much hydrogen is in the water, with a level below 7 meaning that, due to the hydrogen levels, it is more acidic. A pH level above 7 means that it is more a base (or alkaline).

    Most alkaline waters on the market seem to fall somewhere in the range of 7 and 9. This is higher than other types of drinking water, such as tap water, bottled water, or super oxygenated water. Note that there's no proven scientific research that identifies the optimal pH of alkaline water.

  • What are the benefits of Alkaline Water?

    There is no consistent clinical evidence to support the purported health benefits of alkaline water. That said, some studies have connected higher pH water with improved health.

    For instance, one piece of research noted that water with a pH of 8.8 can help treat acid reflux disease. Other studies have linked drinking alkaline water with restoring blood viscosity—the blood's ability to flow healthily through the body's vessels—after exercise.

What Experts Say

"Hydration is essential for good health and can help to optimize immunity, digestion, physical performance, and much more. While there is not adequate research to support some of the health claims around alkaline water, naturally alkaline water (from passing through springs) contains minerals and electrolytes that can help enhance hydration. Simply having a bottle of water with you at your desk or in your bag will inherently remind you to drink more water. If you’re not a fan of plain water, add some flavor by infusing it with fresh fruit or herbs like lemon, lime, cucumber, and mint." Nathalie Rhone, MS, RD

Why Trust Verywell Fit?

A personal note on my recommendations written above. As a dietitian, I am careful to recommend ingestible products, including beverages like enhanced water. While I believe that we need to look at clinical research to make health claims, anecdotally, some people feel better or are more apt to engage in healthy behaviors with a product that makes them feel good.

While there may be a lack of clinical evidence to support health benefits associated with alkaline water, if people drink more water as a result of the great tasting product, I would view that as a net positive. I believe the products in this round-up are superior in quality, and I would feel comfortable recommending them to my clients, friends, and family. Eliza Savage, MS, RD, CDN
