2023 Buyers Guide to the Best Water Ionizers

The investment for a water ionizer is considerable. Before purchasing a water ionizer, make sure you understand what you’re buying. Data shows that consumers searching for the best water ionizer were most interested in the unit’s ability to provide healthiest hydrogen levels regardless of the alkaline or acidic preferences.

Reading in-depth scientific data about ionization and water pH balance can be confusing. Talk to a professional or contact the manufacturer for more details to find the best solution for your home or office water needs.

Even though installation takes less than ten minutes, and the unit is a compliment to your kitchen appliances. In the end, it’s about getting quality results.

The top-rated water ionizers on the market all use electrolysis, which divides the water into acidic and alkaline. Then they deliver top quality water right to your kitchen. There are several features that are imperative to consider before purchasing your first, or replacing an old water ionizer. These include how much space you’re willing to give up, the types of plates the alkaline ionizer uses, and power.

Key Considerations When Choosing A Water Ionizer Machine

Type Of Ionizer

Ionizers come in three main types: convertible, under-counter, countertop. where are you going to give up space? Under the kitchen counter or on top of it? If you can’t decide, then convertible is the best option. However, you will lose space in either one of these areas. The benefit of a convertible is that if you need counter space temporarily it can migrate to under the counter.

Plate Type

Plates are what make your ionizer, well ionize. They convert your water into a wonderful alkaline water. This is where the bulk of the quality is because the better the plates, the better performance you should expect from your device.

These are the types of ionizer plates available:

• Grid is the best available and highly efficient.
• Mesh is also highly efficient and delivers exceptional quality.
• Flat options offer great durability and decent quality.
• Slotted plates are typically low quality and found in cheaper units.

Filtration

Filters are a bonus option for many water ionizer owners. This is a plus and not available on many of the ionizers you’ll find on the market. However, if you find a machine with a carbon filter keep in mind that these filters must be replaced regularly.

UV Light

UV lights are used to sanitize your water. They do this by eliminating viruses and bacteria that is present. Many people find this as peace of mind when they hook up their water ionizer to their faucet.

Power Supply

You don’t want to unbox and install your water ionizer only to find that it dribbles out slowly on its maximum level. But, this shouldn’t happen with any half decent power supply. Usually, a water ionizer should have a SMPS supply that is both energy efficient and delivers a fair amount of power.

Is Ionized Water Safe to Drink?

Even though there isn’t a ton of data to back up the benefits associated with drinking alkaline water, the evident effects are hard to argue. Although the benefits aren’t guaranteed, the safety of ionized water is. The process of ionizing water only affects the pH balance and removes a few impurities based on the quality of the plates.

Final Thoughts on Buying an Alkaline Water Machine

A water ionizer lets you finetune the pH balance of your water from acidic to alkaline. It uses electrolysis to force an electric current through the water to cause a chemical reaction. In the process of electrolysis, super-hydrating electrolytes are formed, like the kind in water-based sports drinks.

Pure, safe drinking water, and filtered water that improves your laundry’s quality, keeps your skin soft and healthy, keeps your appliances running better and longer, and overall enhances your lifestyle.
