Many of us don\u2019t put much thought into the water we drink and we simply just pour a glass of water from the kitchen tap and drink away. In reality, water supplies can vary a great deal and some of them may contain potentially harmful bacteria or other contaminants, even if you get your supply from the main utility company. Water Ionizers are a way of removing such contaminants and controlled the pH level of the water supply, whether you want to adjust the alkalinity or acidity. We have created this article to help explain what ionized water is, how it can benefit your health and wellbeing and guide you towards the best products on the market.

As such, we have tried to offer a comprehensive overview of all the key information you would need to make an informed and educated decision. We believe a water ionizer has the potential to offer great tasting, healthy water for everyone in your household and the products listed are all ones that we feel would do that job the best. Once you understand the benefits of ionized water and what your requirements are, it shouldn\u2019t take long to find the right product for you. What is ionized water In its basic form, ionized water is any water that has passed through a water ionizer machine, to create water that has been both purified and had the pH level changed so that it is more alkaline. It can sometimes be referred to as electrolyzed reduced water or artificially alkaline water. How it differs from normal water The difference is to do with the components within the water and the level of minerals such as calcium, potassium, magnesium and many others. In general, we would expect water from a tap to have a pH level of 7, or neutral, whereas alkaline water will be a higher number and there have been studies to suggest that drinking water at a pH level of 8.8 can help with certain conditions such as acid reflux. How do they work? A water ionizer is connected to your water supply so that when you turn on the faucet, water passes through the ionizer and comes out of the tap as ionized water, in the same way, a filter would do. As water enters the ionizer, it separates the magnesium and calcium from the bicarbonates using a number of plates that are electromagnetically charged, producing two streams of water, one that is acidic and one that is alkaline. It is this alkaline water that gives you tap water to cook with or use as drinking water. Key Considerations There are some key considerations for any customer to be aware of, when deciding to purchase a water ionizer and we\u2019ve listed them below. With a better understanding of the key features and requirements, you will be able to narrow down your search and make an informed purchasing decision. Plates You may have noticed that water ionizers use plates to convert the water into an alkaline pH level and as a result, the number and types of plate are so important. In general, the higher number of plates the better but the more affordable ones will have around 5 plates. You can go up to 11 plates at the higher end of the budget and have a greater pH range to choose from, as well as a better ORP (Oxidation-reduction potential). pH Levels Ultimately, this is what a water ionizer does, it produces alkaline water and so the pH levels available with each product are very important to consider. If you think about the pH scale where 14 is very alkaline, 7 is neutral and 1 is very acidic, then you know you want to find a machine that offers a good range of pH levels. Furthermore, each type of water (acidic to alkaline) has a different purpose and suitability, so the greater the range, the greater the use for the water ionizer. Filtration The majority of households will want to use a water filter in some form, even if the water comes from the local authority. Ideally, you should aim for a water ionizer that has a built-in water filter and think about how good that filter is. Does it provide strong enough filtration for the type of water supply in your area? Equally, consider the longevity and maintenance requirements for those filters, as they can add to the lifespan and running costs. Installation Fortunately, almost all water ionizers are relatively quick and easy to install, requiring minimal experience. Throw in the fact that most manufacturers provide good instructions and support online or via the telephone and you can\u2019t go too far wrong. Having said that, do check out our reviews on the installation to make sure you don\u2019t pick one of the more difficult ones, unless you have the confidence to do so or are happy to pay for professional support. Frequently Asked Questions How long does ionized water last for? In general, you can expect ionized water to stay keep its antioxidant properties for around 18-24 hours, with the pH level gradually dropping after 3 days. If you store it correctly, then you can extend this lifespan to around a week, making it a great choice for most households. Which is the best alkaline water machine to buy? A difficult question and one that cannot be answered in one sentence. It is important to consider your household requirements, understand the key features and factors involved in choosing a water ionizer and then make an informed decision. Our list of the 10 best water ionizers has a fantastic range for almost any household, so we are confident you will find the right one for you. How easy is it to install a water ionizer? We are pleased to say it is normally very easy to install a water ionizer and all modern ones come with fantastic instructions and support in the form of videos or customer service helplines. It is important to make sure the one you choose doesn\u2019t require additional installation procedures, particularly if you\u2019re a DIY novice but each one will tell you in their article. The Pros and Cons It is important to note that a lot of the benefits and research out there on the subject, is a mixture of speculation and evidence, so it is important to reflect on the potential benefits and researching supporting those benefits. We\u2019ve listed some of the common pros and cons linked to ionized water so that you can make your own mind up. Pros Perhaps the most positive attribute of ionized water is to do with its antioxidant properties and the potential benefit this has on your body by drinking water full of hydrated minerals. This is also believed to help with your skin and immune system. Furthermore, it is a matter of opinion but there are many out there who feel ionized water tastes better than the standard water you get from a tap, in part due to its purity and the ionization process. Cons Whilst there aren\u2019t cons as such to drinking water that is Ionized, keep in mind that many of the benefits claimed by manufacturers and researchers are not supported by scientists and doctors, who view them as not convincing enough. One important fact to note is that some of them say you need to understand the water source before knowing how beneficial ionized water is.
