Alkaline Water Filter Evaluation Criteria


When looking at alkaline water filters, it’s important to understand the main features you need to look for and what criteria to use when comparing. These are some of the top criteria we compared when looking for the top alkaline water filter system.

Filter Type

There are a few different types of alkaline filters. There are different physical designs, such as an alkaline filter pitcher, an alkaline water bottle, countertop, or inline filters. What we’re most interested in is the technology behind it, which are the two main types below.

A water ionizer often allows for a lot of flexibility, allowing you to select the pH level so that you can set your water to more acidic for things like cleaning, and more alkaline for drinking. These usually have their own dedicated faucet and are often installed under the sink in your kitchen.

A reverse osmosis water filter system typically removes a large number of contaminants from your water, providing you with some very well purified water. Typically, these filters include a remineralizing layer that can also increase the pH to alkaline levels.

pH Range

One of the main reasons you’re probably here is because you’ve heard that drinking alkaline water has many benefits. This is why this is one of the main criteria we looked at. Some water filters allow you to adjust the range of the pH, but many allow only a certain level.

It’s important to understand pH a little. Acidic levels of pH are those under 7. Many people like to use acidic water for things like cleaning, partially because it naturally works as a mild disinfectant and has antimicrobial qualities. 

A pH above 7 is considered alkaline. Some people like to have alkaline drinking water because of its reported health advantages. 

ORP Level

The ORP level stands for oxidation-reduction potential level. This is, basically, the antioxidant level of the water. High ORP levels can help rid the water of proteins and bacteria. This is a part of the reason we add chlorine into our tap water, since it raises the ORP level of the water. 

A low ORP level is preferable in drinking water, since the anti-oxidant properties are associated with anti-aging, heart disease, and other health benefits. Because of this, some of the filters below lower the ORP level by a large amount.

Flow Rate

Many water filtering systems reduce the rate of water flow. That can be a little or a lot, depending on the design of the alkaline water filter. This is often because of the multiple layers of filtration the water passes through in the process. 

This happens whether your filter is an alkaline filter or not. It’s important to select a filter that flows enough water for you and your entire family each day. If a filter allows only a gallon per day to flow through it, it won’t be much good for a family of five, for example. You’ll need more than that, and should consider that before purchasing.


While it doesn’t change whether a filter provides alkaline water or not, price is an important factor. If two filters offer a similar outcome, have similar build quality, and offer a similar warranty, you might want to consider price as a comparison factor.

No matter how good a filter is or what it offers, it does you no good if you can’t afford to buy it. Some filtration is better than the zero filtration you’ll get if you don’t have a filter at all because the one you want is too expensive. You’ll find filters with a wide range of prices below, so consider that when you buy.

Alkaline Water Filters Buyers Guide


What Are Alkaline Water Filters?

An alkaline filter is a water filter that uses some process to raise the pH of the drinking water above 7. They commonly do so through some type of ionization process, whether that is electrically or through an ionizing filter that uses a mineral like calcium.

Typically, these water filters raise the pH of the water to 8 or higher, which can provide some interesting health benefits. Among the reported benefits of alkaline water are:

  • Higher energy
  • Less cell damage
  • Lower blood sugar

How Do They Work?

Alkaline water purification work by filtering the water to reduce contaminants, then altering the pH level above 7. This can be done by adding minerals, and this is often how an alkaline water filter pitcher works. Another method that is commonly used in an under-sink water filter and in countertop systems involves using electromagnetism to remove carbonate from the tap water, which raises the pH of the waterl.

The filters that work by adding minerals often have what they call a remineralization filter. This adds beneficial alkaline minerals, such as calcium and magnesium into the water. This is often one of the layers in reverse osmosis systems, and it works well because the reverse osmosis filtration removes many minerals in the first place. Remineralization adds the proper healthy minerals back into the system.

Benefits Of Alkalized Water

People who drink alkaline water may see a variety of health benefits.

Anti-aging- Alkalized water is high in antioxidants. These antioxidants help prevent cell damage and can help limit cell damage. By preventing this damage, we’ll get an overall anti-aging benefit over the long run.

Better hydrating- Alkaline water has smaller water molecules than acidic water or neutral water has. Because of this, it is thought that alkaline water is more easily absorbed by the human body. Water with a higher pH can help you hydrate more than typical drinking water.

Better immunity- There is some evidence that a high pH in your drinking water can help neutralize acids in your body. This is especially true if you have a bad diet. By neutralizing these acids, it’s thought that you may increase your immunity.

Added minerals in the alkaline water can aid immunity, help you sleep better, and improve your overall mood.

These are just a few of the benefits you may see if you drink alkalized water.

Types Of Alkaline Water Filters

While we discussed the types of filters above, let’s take a more detailed look at the various physical forms of alkaline water systems you may find.

Pitchers- An alkaline water pitcher is much like any other pitcher in appearance, but it has the added benefit of raising your water pH. It usually does this by having a pre-filter tank on top, a post-filter tank, and a filter between them. You fill the pre-filter tank with tap water and it runs, typically by gravity flow, through the filter and into the ready-to-drink post-filter tank. 

These pitchers are small, but that makes them portable. You can top up your pitcher, then carry it off into another room. Alkaline water filter pitchers can be placed in the refrigerator to keep water cold and ready to drink. It has the downside of providing a very limited amount of alkalized water.

Countertop- A countertop alkaline water filter system works much the same way the alkaline water pitchers do. They have a pre-filter tank, a filter, and a tank that holds water that is ready for use. Like the pitchers, these are usually designed so that water flows through the water filter using only gravity.

Countertop models are usually larger than pitchers, and can often hold 3 to 4 gallons of water. Some of these require you to manually add water to them, but many can connect to your faucet using a diverter valve. While these aren’t quite as portable as the pitchers, they can easily be disconnected and moved from place to place if you need to relocate them.

Alkaline water bottles- Alkaline water bottles are just like a typical water bottle, but the water flows through a filter as you drink. These usually add minerals to increase the pH, so the water you drink will have higher levels of calcium, magnesium, or other alkalizing minerals than your water supply has.

Under-sink- An under-sink water filter can often work differently. Many use an electromagnetic ionizing system, rather than adding minerals. Some add healthy minerals, as well. These often produce a larger amount of drinking water than the other alkaline water systems, and they are usually much more expensive. They are also much larger and take up more space.

Most of these are designed to pump the water through a dedicated faucet. Because of the more permanent connections required, these aren’t portable after installation. They do have benefits, such as often offering multiple levels of pH that you can select from. 

Considerations When Looking At An Alkaline Filter

When buying an alkaline water filter, there are a number of things you should consider. While we discussed most of these above, some of the criteria you should consider are:

  • Filter type
  • pH range
  • ORP level
  • Flow rate
  • Price

There are also other things you should consider. 

Contaminant removal- Think about how many other contaminants an alkaline water filter can remove. While pH is important, you can often get a filtration system that will provide extremely well cleaned and well purified water as well. These can be contaminants like chlorine, lead, and other heavy metals. They can often help kill off bacteria and can remove some of the harmful chemicals in your drinking water.  

Maintenance and installation- Consider how hard it is to maintain a water filter before you buy it. Will you need to spend a lot of time changing filters or monitoring how well the system is working?

If a water filtration system is easy to install you can save a lot of money on hiring a plumber, so consider if it’s DIY-friendly.  

Warranty- A long warranty on a water filter can help you rest easy and save a lot of money. Consider a filter whose warranty has expired. If anything on it seems wrong, you’ll worry about how much it’s going to cost you to fix. Or maybe you’ll wonder if you’ll need to replace the whole thing. 

If your water filter comes with a long warranty, if anything goes wrong you know the manufacturer will have to take care of most of the cost. This lets you let go of a lot of worries. Every strange sound near the system won’t have you living in fear that you’ll have to shell out big money to fix your filter.

Frequently Asked Questions

Are Alkaline Water Filters Safe To Use?

There is a lot of evidence to suggest that alkaline water is safe. In fact, there are many health benefits that you may notice. Many of these filters not only raise the pH, they also add beneficial minerals to your drinking water. But on top of that, a lot of people notice better tasting water and and better smelling water after using one of these filters.

How Do I Change An Alkaline Water Filter?

How you go about changing an alkaline water filter can be different, based on the system. Some require you to simply screw out an old filter cartridge and screw in a new filter cartridge, some require you to open up the system and pull the filter out. Many systems have filters that last at least six months, but some of the under-sink water filter units have even longer filter life. Many pitchers and countertop units have a very short filter life, and you’ll need to change them constantly. It all comes down to the specific water filter.  

Is It Easy To Use An Alkaline Filter?

In most cases, alkaline filters are relatively simple to use. Some are so easy to use that you basically treat it like a regular water pitcher, aside from changing out a filter occasionally. Others require you to set the pH level and require a more difficult and permanent installation. In nearly all cases you need to change filters or cartridges.

Can An Alkaline Water Filtration System Remove Contaminants?

Many alkaline water systems do not just increase your water’s pH level, they also do a good job of filtering the water. This, in a lot of cases, includes the ability to remove contaminants like fluoride, chlorine, lead, heavy metals, VOCs, and more. These filters can produce extremely pure drinking water.

But there are some alkaline systems that remove only basic sediments as they alkalize your water, and some that may only alkalize the water. Read our reviews for each filter before you buy it, and always check the levels of contaminants they remove before you purchase.
