How do water ionizers differ in pH range?

Different ionizers produce different pH ranges. Some reach super-alkaline (pH 11.5+) or very acidic (pH 2.5-4) levels, which are useful for cleaning but not for drinking. Look for machines that cover the ideal drinking range of about pH 7-10. The extremes of pH (high/low) can only be attained by adding saline, which requires a port and also can harm the water ionizer.

What types of plates do water ionizers use?

Ionizer plates can be solid, mesh, or coated with platinum. Mesh plates provide more surface area for ionization, while advanced electroplating ensures long-lasting performance. The type and quality of plates directly affect the machine’s efficiency and durability. (See #12 in the section above called 'Explaining the Features')

How important is automatic cleaning?

Though all the water ionizers use automatic cleaning, only a rare few use a special feature, called 'automatic continuous-cleaning'. These advanced systems maintain plate efficiency over time, reducing calcium buildup, because the cleaning is continuous. Machines with only intermittent acid-wash cleaning may require manual intervention and can affect long-term performance. (See #12 in the section above called 'Explaining the Features')

What should I look for in filtration quality?

Most water ionizers use high-quality filters, which remove chlorine, heavy metals, fluoride, and microbes. But AlkaViva and Jupiter brands of water ionizers use advanced UltraWater filtration, offering multiple stages for optimal water purity for 249 contaminants up to 99.99%.

Does power supply affect water ionizer performance?

Yes. Switch-mode power supplies are lighter and more energy-efficient, while traditional transformers are robust. Both are reliable, ensuring consistent ionization, especially for machines with multiple plates or advanced features. (See #41 in the section above called 'Explaining the Features')

Are there differences in molecular hydrogen or ORP performance?

Some ionizers produce higher antioxidant levels (more negative ORP) and more molecular hydrogen, which can enhance health benefits. Side-by-side testing is the only way to reliably compare this feature. (See #17-18 in the section above called 'Explaining the Features')

How do installation options vary?

Water ionizers can connect via countertop diverters, under-sink plumbing, or dedicated faucet kits. Consider your kitchen setup, water pressure, and preferred convenience when choosing an installation type.

What are the health benefits of alkaline water?

Alkaline water may improve hydration, reduce acid reflux, and support antioxidant defenses through negative ORP. Many users report enhanced energy and digestion.

Why are alkaline water machines (water ionizers) so expensive?

Electric water ionizers are more expensive because they use pure titanium plates covered with medical-grade platinum (~$1500/oz), include high-quality design, electronics, workmanship, and warranties, and ionize all naturally occurring minerals like calcium, magnesium, and potassium. Non-electric ionizers only ionize magnesium and are less effective. Compared to medical equipment or years of bottled water, they are cost-effective.

Why do water ionizers (alkaline water machines) use platinum-coated electrodes?

Platinum-coated electrodes are essential because platinum is extremely durable and corrosion-resistant. Combined with titanium, electrodes last virtually a lifetime and catalyze the electrolysis process, allowing water to be ionized instantly as it flows through the electrolysis chamber.

Which brand/model of alkaline water machine makes the best water?

Several properly manufactured water ionizers are considered the best if they achieve a wide pH range, produce antioxidants at each alkaline level, and include a good warranty. Other features can be compared in the Water Ionizer Comparison Chart.

Are there any cautions about drinking ionized alkaline water?

Start slowly at the lowest alkaline level, and increase gradually if the water agrees with you. High alkalinity (9.5-10.0) is best for drinking; highest levels can be used for cooking. Use the 'Purified Water' setting for medications. Do not drink acid water from the lower spout.

What is pH and how do I test my body's pH?

pH means 'potential hydrogen' and indicates acidity or alkalinity on a scale of 1-14. 1-6 is acidic, 7 is neutral, 8-14 is alkaline. Saliva should be slightly alkaline (above 7.3) for optimal health. Free urine/saliva pH test kits are available.

Which container, or bottle, is best and what's the best way to store ionized water?

A vacuum stainless steel bottle is the best choice. The second best is a mason jar. Proper storage maintains the water's alkalinity and antioxidant properties.

Does it change the pH or ORP of ionized water to mix it with flavor-aids or alcohol?

Yes. Chemically-created drink mixes like Kool-Aid or Crystal Lite reduce the pH and ORP benefits of ionized water, making it acidic. Alcohol, like scotch, does not reduce pH or ORP.

What are the differences between electric and non-electric water ionizers?

Electric water ionizers are more expensive because they require high-quality pure titanium plates coated with medical-grade platinum. They ionize all beneficial alkaline minerals like calcium, magnesium, and potassium, which are more easily absorbed by cells. Non-electric water ionizers are primarily filters that add magnesium in the presence of magnets. Electric ionizers are superior because they ionize all naturally occurring minerals.

How does a water ionizer work?

A water ionizer uses electrolysis to separate water into alkaline and acidic streams, increasing pH and adding molecular hydrogen for potential health benefits.

What is a naturally ionizing alkaline water filter?

A naturally ionizing alkaline water filter uses mineral-based filtration, such as magnesium and ceramic materials, to raise the pH of water and provide antioxidants. These filters do not require electricity.

Is alkaline water better than filtered water?

Alkaline water offers added benefits like higher pH and antioxidants, while filtered water simply removes contaminants. The best choice depends on your health goals.

Are there any cautions about drinking ionized alkaline water?

You should increase the pH slowly. Start with the lowest alkaline level and increase gradually. Drinking water that’s too alkaline too quickly may cause temporary discomfort. Always introduce new health habits slowly to let your body adjust.

Why do electric water ionizers need platinum coating on the electrodes?

Platinum acts as a catalyst, speeding up the electrolysis process. This ensures immediate and efficient ionization of the water.

Is platinum in water ionizers safe for the body?

Yes. Platinum used in ionizers is safe, and nano-platinum particles may have beneficial effects on the body according to some research.

Which water ionizer do you suggest?

We offer several high-quality water ionizers. You can compare features and prices on our Water Ionizer Comparison page.

What level of alkaline pH is best for drinking?

Most people prefer drinking water with a pH between 9.0 and 9.5. Start with a lower level and increase gradually based on how your body responds.

What are the highest alkaline levels, like 11 pH, used for?

Alkaline levels around 11 pH are typically used for cooking and cleaning, as they help break down grease and grime effectively.

What is the Purified Water setting used for?

Purified Water is neutral pH water that is only filtered, not ionized. It’s ideal for taking medications or for young children and infants.

Can you drink the acid water that comes from the lower spout?

No. Acidic water is not for drinking. It's intended for external use, such as cleaning, disinfecting, or watering plants.

What is the best way to store ionized water?

Store ionized water in an airtight, non-metallic container, ideally in a cool, dark place. This helps preserve its antioxidant and pH properties.

Can babies or toddlers drink alkaline water?

It's best to use the Purified Water (neutral pH) setting for babies and toddlers. Their bodies are naturally alkaline and may not need additional pH boost.

Why Drink Alkaline Ionized Antioxidant Water?

Alkaline ionized water offers more than just hydration — it supports your body’s natural ability to detox, energize, and stay balanced...

Is alkaline water safe to drink every day?

Yes, it’s safe for most people when consumed in moderation. Start with lower pH water and gradually increase. Avoid very high pH (>10) during meals.

Can children drink alkaline water?

Children can drink mildly alkaline water (pH 8–9). For children with specific health conditions, consult your pediatrician first.

How Ionized Water Acts as an Antioxidant

Ionized water provides millions of electrons that neutralize harmful free radicals. Unlike traditional antioxidants, hydrogen simply evaporates after donating its electrons — leaving no negative byproducts behind.

PH & ORP — What Do They Mean?

PH stands for "potential hydrogen" and indicates acidity or alkalinity. Water with pH >7 is alkaline and helps balance an acidic diet.

ORP measures antioxidant potential. Negative ORP (found in ionized water) means stronger ability to combat oxidation in the body.

Is bottled alkaline water the same as ionized water?

No. Bottled water loses molecular hydrogen quickly and does not maintain negative ORP. Electric ionizers provide fresh, high-antioxidant water on demand.

Can alkaline water help with acid reflux or digestion?

Many people report relief from acid reflux and improved digestion with regular alkaline water. Some studies suggest pH-balanced water can neutralize stomach acidity.

Are there any cautions when drinking alkaline water?

Start slowly with the lowest setting. Gradually increase pH and intake.

Does alkaline water help with weight loss?

Alkaline water may support metabolism and fat-burning indirectly by reducing acidity and improving hydration, but it is not a replacement for a healthy diet and exercise.

Do I need to drink a lot to see benefits?

Start with 4–8 cups per day. Consistent use over weeks to months yields the best results.

Can I use alkaline water for pets or cooking?

Mild alkaline water is safe for pets. Using it for cooking can enhance mineral content and flavor, but extremely high pH water is not recommended for daily cooking.

Cost of a Water Ionizer?

Investing in a water ionizer is a smart long-term health choice. Daily cost for a family is roughly $0.50. High-quality ionizers use platinum-coated plates and advanced electronics for durability.
