Alkaline water is a trend that has been spreading all over the world, and for good reason! It is full of minerals and antioxidants which help support your immune system. However, not everyone knows that there are many different types of alkaline water machines on the market today. To make sure you’re making an informed decision about which machine to buy, we’ve done the research for you. In this blog post, we’ll be reviewing three different machines as well as providing some tips on how to use them properly.

Water ionizer machines increase the alkalinity of water by altering its pH.

Water that has traveled through an ionizer machine is known as ionized water. A standard alkaline water machine contains metal plates, usually titanium and platinum. These use the process of electrolysis to divide up the key ions in the water, resulting in a water with a more alkaline pH level.

So why do people prefer alkaline water? Actually, it’s more than just a case of personal preference. Alkaline water is thought to reduce impact of oxidation on the body.

It’s also said to provide key nutrients for hydration, energization and detoxification. We’ll cover the benefits of alkaline water in more depth later on in this guide.

How To Choose The Best Water Ionizer

Under counter vs countertop

The size of your kitchen or where you plan to place the machine will be key considerations when it comes to choosing between an under counter and a countertop model.

Under-counter water ionizers are usually more expensive but they do save on space – especially if you have other appliances in your home taking up valuable cupboard space! They also tend to be stronger, faster at filtering out impurities (which is ideal if you live in areas with hard tap water) and generally look nicer too.. If cost isn’t much of an issue for you then this option can offer better value for money overall.

On the downside however these machines require professional installation which means hiring someone else to provide that service (and paying them!) as well as the cost of the actual machine.

Countertop water ionizers are also nice and compact but they don’t usually offer as many filtering features (although this varies between models). They do look really cool though – especially if you want to show it off on your kitchen counter!

Filter efficiency

A machine with a higher filter efficiency is going to be better than one that has lower ratings. This basically means it will remove more impurities from your water at once, so you don’t have to wait as long for the filtered stuff!

Depending on how much time and money you intend to spend on filtering out harmful substances this could be worth bearing in mind when buying an alkaline ionizer.. If your budget isn’t unlimited then look for models which advertise they reduce chlorine or fluoride by up to 99% (or whatever rate is appropriate) – anything less may not give you the results you want.

pH Range

This is a pretty important factor to consider if you’re on the lookout for an alkaline water machine. In terms of health benefits, it’s generally recommended that we drink somewhere between pH=0 and pH+14 (so slightly acidic or neutral). The problem with many tap waters however is that they have a very low level in this range – usually at around pH=+11!

By increasing its acidity you can help your body absorb more nutrients within food while reducing oxidative stress too.. To get all these advantages from drinking alkaline ionized water though your machine needs to be able to increase the ph value by several points which means having an appropriate setting or capability. If yours only goes up as far as +12 for example then you may want to consider upgrading (or supplementing with another product).

There are some machines however that don’t feature a pH adjustment feature at all – instead they leave it up to the user. If you know what level of alkalinity is right for your body and lifestyle this could be an option worth considering.

ORP range

This stands for oxidation reduction potential and it’s a measurement of how much free radicals are in your water. If you have high levels of these then drinking alkaline ionized water can help reduce the damage they cause to cells – potentially reducing cancer risks too!

The higher this number is, the more antioxidants will be present so look out for machines that advertise an ORP range on their product description or website.. You should ideally aim somewhere between +200mV and +1500mV although some models allow you to change this according to what feels best for your body as well as any health conditions (such as arthritis) which may require specific settings.

Simplicity of installation

You’re not going to want to spend hours trying to install your new alkaline water machine are you? If this is one of the main reasons why you haven’t got round buying one yet then look out for models that only require plugging into a power supply and can be set up in just minutes.

As well as limiting installation time, these machines also tend to come with more user-friendly controls too (although some will still need an experienced person to do it). They might not offer quite as many fancy features or filtering capabilities but they make great starter options if you aren’t sure how much use an ionizer would actually get at home!

Manufacturer support

As with any product it’s always a good idea to check out the manufacturer before you buy in case they have been known for providing faulty or low-quality products. This is especially important when buying an alkaline water machine because there are some that don’t actually work as well as advertised!

If possible, try and find reviews from people who have bought these machines yourself – most review sites will allow you to filter results by brand if need be.. Also make sure you read up on any warranty information offered (in terms of both time and money) although this varies between brands too so do your research beforehand.

Water ionizer maintenance

  • How to know if a water ionizer needs cleaning?

If you store your ionizer in a cabinet, it is important to remember that when the door opens and closes every time, particles of dust can get into its system and cause problems over time. This will not be an issue if it’s kept out on top of your countertop or under the sink instead! Also make sure to clean any mineral deposits from inside all removable parts regularly as well since they may affect calcium levels dispensed by this alkaline water machine once accumulated over time which might lead to unpleasant tasting drinking water after some point.

You’ll know when cleaning day comes around because scale build up will start happening at a faster rate than usual but don’t worry– most units come with built-in reverse osmosis technology included so they can be safely rinsed out with water so there’s no need to get any special cleaners or chemicals involved at all!

  • Maintaining your water ionizer – do’s and don’ts

Remember to unplug your ionizer before cleaning it and use only water on the parts of this alkaline machine that can be rinsed with water. Special chemical or cleaners should never be used because they could damage the unit’s internal components!

Make sure you don’t leave any containers under its spout for an extended period of time since leaving them there too long might cause leaking, overflow or other problems down the line so make a habit out of checking what is underneath every few days to avoid such issues from ever occurring in your household.

Also keep in mind that if left sitting unused for longer periods each day it’s best not to put anything but plain tap water inside until ready to go again as distilled drinking water will lead up scaling up much faster than tap water alone which can lead to extra cleaning needed before getting back to enjoying the ionized alkaline benefits of this machine.

  • Cleaning instructions for a water ionizer

To clean the system, first unplug it and then take off all parts that can be removed for cleaning. Do not use any harsh chemicals to descale as they may damage this alkaline water machine so instead just brush out mineral scale buildup with a toothbrush before rinsing thoroughly with hot tap water until no more build up comes off easily.

Allow those parts to dry completely before putting them back together again and plugging in the unit once again after which you’re ready to start enjoying great tasting alkalized drinking water from your own home without having spent too high an electric bill at end of month!

Frequently Asked Questions

Can I still use my normal tap water when I connect my faucet to an ionizer?

While it is best to use neutral or purified water when using an ionizer, tap water can be used but will require more cleaning after some point. However this alkaline machine’s benefits are still worth the extra effort in most cases!

What are some harmful contaminants that a water ionizer can remove?

Water ionizers can remove fluoride, chlorine and other harmful contaminants from your drinking water so if you have any of these around the house it is best to get rid of them before using this alkaline machine!

Can I use a water ionizer for my pets?

Many water ionizers can be used for pets, but it is best to double check that the one you buy comes with a pet drinking fountain feature if this is what you’re going for since some do not have them and may require an extra product purchase.

If your machine does come with a special bottle for your furry friend or other animal in your house, make sure you clean it regularly so that your pets can continue to enjoy healthy drinking water from this alkaline machine!

What advantages does a water ionizer have over a standard or reverse osmosis water filter?

Water ionizers have many advantages over standard or reverse osmosis water filters including the fact that they are able to remove more harmful contaminants, produce alkalized drinking water and may require less maintenance overall.

Why do some water ionizers let me change pH levels?

Water ionizers that let you change the pH level of your drinking water to a higher or lower number can be beneficial depending on what you’re looking for. If you’d like to make antioxidant rich alkaline water with this machine, then it’s best to go high in pH since most antioxidants are very sensitive and will deteriorate at different levels causing you to miss out on their benefits if the pH is too low!

Can I store alkaline water?

Some alkaline water machines have features to allow you to store the water that is made inside them for a longer period of time, but it’s important not to keep any ionized drinking water in this machine overnight or over a long weekend since distilled and ionized alkaline drinking water can lose many benefits overtime.

Do different people need to drink water at different pH levels?

Different people may have different needs for their drinkable water depending on what they’re looking to get out of it. For example, antioxidant rich alkaline drinking water is best at a higher pH while other types might be better off lower in pH!


Water ionizers are a great way to make tap water healthier and more alkaline. An ionizer is an appliance that attaches to your faucet and produces high quality, pH balanced drinking water on demand by removing the acidic heavy metals from regular tap water. Ionized or alkalized water has been shown in studies to have many health benefits including increased energy levels, weight loss success, better sleep patterns, improved skin health and reduced risk of chronic illnesses like cancer.
