These two types of water have specific benefits and applications. Water filtration is used to improve the quality and of your drinking water, and remove common contaminants such as microbes, heavy metals, and chlorine.  For more see – what is ionized water.


Water is ionized using an electrochemical process known as electrolysis. The process is used to create two types of ionized water – alkaline and acidic water – each with a range of special advantages.

deionized water

And unwanted pollutants are removed from the water as it passes through the filter. As contaminants contact the filtration media inside the filter they are trapped and held in place – removing them from the water.


Our buyer’s guide will take you through the most important points to consider when buying an ionized water filter. Let us help you choose the best ionized water filter for you and your home that meets your needs and matches your budget.

What type of ionized water filter are you after? Do you know what type of device you will be using to make your ionized water? There are three main types – ionized water machines, ionized water pitchers, and ionized water faucet units.

Each one of these types of water ionizer will use a different type of filter, so if you don’t already know, you will need to decide on the filter type you need to buy.


This is a special type of water pitcher that converts regular tap water to alkaline ionized water. It uses a filter to alkalinize and purify the water as it passes from an upper reservoir to a lower reservoir inside the pitcher. Pitchers are a very cost-effective way of producing small quantities of ionized water.


An ionizer machine is a device that sits on your kitchen counter and produces ionized water using a process known as electrolysis. These devices often have filters added to purify and improve the quality of the ionized water. Ionizer machines are the best option for producing large quantities of high-quality ionized water.


An ionized water faucet filter is a special type of filter that is fitted directly to your water supply below your kitchen faucet. It is often fitted out of sight below the counter and ionizes and purifies water before it comes out of the tap. Once fitted they are a very convenient way of producing regular hassle-free ionized water.


When investing in an ionized water filter for your home, consider how much ionized water you will need. The different types of filters outlined above are each designed for different water capacity levels.


On the lower capacity end is the ionizing water pitcher. These pitchers vary in size but generally produce between 1.5 to 3 liters of water per fill. These filters have a limited life span and typically have to be replaced every 1 to 2 months.


An ionizer machine has a greater capacity and depending on the individual machine you choose, they can produce between 2 to 3 liters per minute. The filters used in these machines are much more robust, usually needing to be replaced once every 12 months.


An ionized water faucet filter is designed for high capacity. All the water coming through your tap will be run through the filter, ionized, and filtered. While there’s a bit of work getting the unit fitted and replacing filters at the end of the lifecycle, it is the most convenient option during regular operation.


When buying a water filter – you need to consider how effective the filter is at removing contaminants. Most water ionizing devices come with a filter that purifies the drinking water, making it safer for consumption.

Water filters remove unwanted pollutants such as chlorine, heavy metals, microbes, organic compounds, and herbicides. The filtration performance will vary from model to model, so take a look at the manufacturer’s specifications and check the filter performs as you need it to.

Every water filter has a limited life expectancy. This should be detailed in the filter product description. As with anything, you get what you pay for. The filters on the cheaper end of the price scale have very limited life spans, while the more expensive filters will last longer.

Take a moment to weigh up the price of the filter against its life expectancy. Filter life expectancy is often defined by its water capacity, for example, a filter may have a life expectancy of 6,000 liters. Many filters come with a built-in indicator that will notify you when it is time to replace the filter.


What is the pH range of the filter? The pH scale runs from 0 to 14. Seven is neutral, indicating that a substance is neither acidic nor alkaline. Anything below 7 is acidic, while anything above 7 is alkaline. Zero is highly acidic and 14 is highly alkaline.

Check the pH altering ability of the ionizing device you are interested in. This should be included as part of the product specification. The best water ionizing filters let you set the desired pH range you can choose exactly the type of water you want.

Most people use ionized water filters to produce ionized alkaline water for drinking. This type of ionized water should have a pH between 7.5 and 9.0. Anything above this is too alkaline for consumption.


Is the ionizing water filter easy to use? You want to pick a filter that you are comfortable using. The ionizing water machines and ionizing pitchers are very easy to use. But, an inline faucet filter will require some installation work.

Take a look at the operating instructions that come with the device and make sure you would feel comfortable using the ionizer before committing to a purchase. There’s no point buying an ionizing filter only to find it is difficult to operate.


All ionized water filters have to be replaced when they reach the end of their lifecycle. They have a limited amount of water they can ionize and purify. Check the expected lifespan of the filter to see how long it will last.

Then take a look at the instructions for how to replace the filter. Is it a simple process? Will replacing the filter be something you feel comfortable with?

Also, make sure the company supplies replacement filters and that they are easy to order when you need them. How much do they cost? Generally, the more expensive the filters have longer lifespans and better performance – but not always!


Do you like the look of the device? Has it been well designed?  Consider the ergonomics and aesthetics of the device. If it’s a countertop unit it will be sitting in plain view in your kitchen. Are you have with how it looks?

How about the ergonomics? Is it designed for easy handling and operation? Not all water ionizer filters are designed equally. Take a moment to consider if the design is right for you.






Take a look at the price of the device. Does it match your budget? The price of ionized water filters varies greatly across the three different types – ionized water machines, ionized water pitchers, and tap/faucet ionized water filters.

The cheapest will certainly not be the best, so don’t let price be your deciding factor. You should weigh up the price against all the points outlined above and compare and contrast against different models. Investing in the right ionized water filter now will save you time and money down the road.


Does the filter come with a warranty? What time period does it cover? The best ionized water filters come with substantial warranties. Compare the warranties offered across similar models and see what’s on offer.

Different manufacturers offer different periods of warranty cover and some offer none at all. The most common warranties on offer range from 30 days right up to 2 or even 3 years.


What kind of support can you expect from the manufacturer after you purchase your device. Do they have a customer service support line? If you encounter an issue with your ionized water filter is there someone you can contact to ask for help?

Take a moment to see what levels of customer support are on offer from the product manufacturer. You could even check online review sites to see how previous customers rate the service provided by the company.
