But let’s not call the whole thing off just yet!

There are two types of systems that can make alkaline ionized water: an alkaline water filter and a water ionizer. However – each of these systems uses a different method than the other.

Read on to learn about which things you should consider when deciding which system to buy to get the health benefits of alkaline water:

  1. What Is an Alkaline Water Filter?
  2. What Is a Water Ionizer?
  3. Should I Buy an Alkaline Water Filter or a Water Ionizer?
  4. What Do I Need to Know Before Buying a Water Ionizer?


What Is an Alkaline Water Filter?

  • Alkaline water filters work to transform and slightly ionize your regular tap water without using electricity by adding alkaline minerals found within the filters to the water.
  • Alkaline ionized filters work great unless your municipal water supply has hard water, which is already saturated with minerals. Hard water is unable to properly absorb the minerals from an alkaline water filter.
  • These filters usually produce a lower quantity of hydrogen-rich antioxidants than electric or non-electric water ionizers.
  • There are two types of alkaline water filters: portable and continuous flow.

What Is a Water Ionizer?

  • Water ionizers work by filtering your tap water that is then converted into alkaline water through the process of electrolysis.
  • Hard water is great for a water ionizer because hard water contains an excess amount of minerals. To carry the electrical charge, these machines require minerals to be present in your regular tap water.
  • Soft water lacks minerals – so you may have a tough time making ionized alkaline water using soft water.

Should I Buy an Alkaline Water Filter or a Water Ionizer?

When it comes to choosing between an alkaline water filter or a water ionizer to make high-quality alkaline ionized water at home – there are a variety of things to consider, such as:

  • pH and ORP
  • Filtration Capability
  • Budget
  • Lifestyle

Read on as we dissect each of these areas to help you decide if you should buy an alkaline water filter or a water ionizer for your home:

pH and ORP

● 1 pre-set pH level

● 1 pre-set ORP level

● You can adjust the pH and ORP levels on each machine to suit your health needs.

● Quality machines can produce alkaline water that’s significantly higher in ORP values (antioxidant potential) than alkaline ionized filters can.

Filtration Capability

  • These filters can only produce limited amounts of ionized alkaline water at a time before the filters run out and need to be replaced– making them less ideal for family sized needs.
  • Alkaline ionized filters usually require a break to fully recharge in between use.
  • An alkaline water machine is capable of stronger, more complete ionization of your regular tap water than an alkaline ionized filter.
  • These machines can make as much alkaline water as you want, whenever you want.

  • These filters are far less expensive than electric or non-electric water ionizers – and range from $30 to $130.
  • Alkaline ionized water filter replacements can get expensive FAST and can ultimately cost you more than if you bought a high-quality ionizer instead.
  • High-quality water ionizers typically require a larger initial investment of $2,500 and up.
  • Lower-quality machines can be found for $999 and under, but beware of ionizers made in China or Taiwan.
  • Some ionizer brands offer a financing program to own one of their machines. Qualified buyers can enjoy friendly monthly payment terms, a down payment of $0, and low-interest rates.

  • These filters can ONLY make alkaline water.
  • Alkaline ionized filters are usually more portable than water ionizers.
  • These filters are a great option for those looking to enjoy drinking healthy water when they travel.
  • High-quality machines can make both alkaline AND acidic water for various uses around the house.
  • Ionized acidic water can be used to treat various cuts and burns on your body or to sanitize various household surfaces. (among other uses)


Our Take:

An alkaline water filter can offer you a simple, economical way to enjoy the benefits of alkaline water – but you’ll eventually realize that a filter’s capabilities are rather limited. Plus, alkaline water filters don’t create molecular hydrogen, so the health benefits are far more limited than the benefits you’ll get from an electric water ionizer.

The best way to get alkaline water benefits is to buy a high-quality water ionizer machine that will provide you the family-friendly convenience of making alkaline ionized water at home whenever you want.
