What is an alkaline water filter?
An alkaline water filter sometimes referred to as a water ionizer, changes the chemical balance of your water supply to make it the healthiest water possible.
The term alkaline water refers to the water’s pH level and being above 7.5. The alkaline water process uses a water separation called electrolysis, where your water will be filtered into an alkaline stream. This process will also add beneficial minerals like calcium, so you are gaining more from your water supply.
Most importantly, the alkaline water filter will make your water the healthiest and best water for your health.
Why you need an alkaline water filter?
By increasing the water’s pH level 7.5 or above (most alkaline filters will increase pH levels to 8-9), you are providing your body with the best water possible. Water with a pH of 7 or below is not as healthy and does always have additional minerals added to it, like an alkaline filter. By making your water’s pH above 7.5, you are making the water “alkaline,” which can neutralize body acid.
There is evidence that alkaline water will be beneficial for people with high blood pressure, high cholesterol, and diabetes. Some studies have proven that people that consume water that has a high pH level will have increase oxygen delivery throughout the body. Alkaline water can also help with immune system support, weight loss, and healthier skin and nails.
The differences between alkaline water and regular water?
The main difference between alkaline water and regular water is the pH balance. Typically, the alkaline water will also have additional minerals that stay with the water throughout the ionizing process that can be beneficial to your health.
These minerals include calcium, sodium, and magnesium. Several questions arise when comparing alkaline water and untreated water. Below are the two most common.
Is alkaline water better than filtered water?
This question is more complicated than it sounds. In a perfect world, your alkaline water filter has built-in water filtering with the ionizer process, or you are running the water through the filter before it hits the alkaline filter. The absolute best water that you can have is a high-quality filter removing common tap water contaminants working concurrently with an alkaline water filter.
Be careful when reviewing alkaline water filters. Some filters are built into a standard water filter, and then there are alkaline filters that are separate, and you should have another water filter to work with it. It is more common for them to be built into the same system but not always. When it comes down to which is better, alkaline, or filtered water, the answer is both.
Is filtered water alkaline or acidic?
This is a very good question, and the answer will revolve around the pH balance of the water. The magic number for alkaline versus acidic water is 7. If the pH of the water is above 7, the water is considered alkaline. When it comes to drinking water, we do not refer to water as alkaline until it reaches 7.5 or higher.
Most of the alkaline filters on the market will increase your water’s pH level to at least 8. In short, water run through an alkaline filter will be classified as alkaline. Without the ionization process of the alkaline filter, even water that is run through a normal filter could still have a pH of 7 or below.
Water is considered acidic when the pH is 7 or below. Acidic water is said to have negative health benefits if ingested in massive quantities.
Acidity can encourage bacterial growth so you will want to do your best to limit the amount of acidic water you are ingesting. Acidic water can be used for several things, however. Washing dishes, cleaning, and cooking are all places where acidic water is OK.
Best Alkaline Water Filter: Consider These Important Factors
Filters
There are a few things you want to look for when it comes to the filters associated with an alkaline water filter. The first and most important thing is to make sure that there is a filtering process within your water ionizer. Some models simply attack the ionization process and do not have any other filtering capabilities. Not filtering the water can remove a lot of the benefits you stand to gain from ionizing your water supply.
Once you have determined the best route for you, you will want to check the filtering capacity of the filtering system that you are using. This could be using a separate filtering system from your ionizer or a combined built-in filtering process.
Based on the amount of water your entire household will use, you want to make sure that you are not constantly changing filters. They are not free and if you are buying filters with a low capacity, you will be buying more filters and spending more cash. Make sure you are accounting for everything you would need your filter for, especially if it is used separately from the alkaline ionizer.
Plates
One of the most important features of the alkaline ionization process is the material and number of plates that are used. If the filter you are purchasing is designed to be used with electricity, then you will have plates in your system. If your system does not use electricity, it will use multiple filtering levels and this section will not be relevant to you.
Plates are used during the electrolysis process where the plate is electrically charged and as water enters the system, the electrolysis being produced by the plates converts the tap water into alkaline water. When it comes to deciding on an electric water ionizer, there are a few things to consider.
Number of Plates
a unit with less than 5 plates. Most of them are now built with anywhere between 5-13 plates and the more plates you have, the more electrolysis the water will undertake, and other benefits you will obtain from the plates.
You will notice that the water flow will be less with fewer plates and you will also have a higher pH level with more plates, which means the water will have more alkaline characteristics. I typically suggest that people do not purchase an ionizer with less than 9 plates. This is a solid number that still handles flow rate and electrolysis well enough to garner the benefits of alkaline water.
If you have the means, 11 and 13 plate models are the absolute best quality and will give you the best performance from your alkaline water filter. You will see that there are models available with 15 plates, but we have found that these are usually used in industrial settings and are too big to use in the home.
Material of Plates
Alkaline water filters have been around for a long time. The material used during the electrolysis process has evolved over time and we believe we are at a point where we can finally tell you the best material for plates. You want to purchase an ionizer with plates constructed from titanium and platinum. Ensure that these are the only two materials that you should be looking for. If you see the word, “alloy,” you need to run away.
Pure platinum and titanium plates have been proven to be the best combination for electrolysis over time. The titanium will usually be the outer layer. It is there because it will be the best option to resist water erosion and it is an ultra-strong material that will last many years. The reason that platinum is the best option is that it is proven to be the best metal at speeding up electrolysis. Thousands of different metal compounds have been tested and these are widely regarded as the best possible combination.
Surface Area of Plates
In addition to the material and number of plates, you also want to look at the size of the plates. Smaller plates will produce less electrolysis within the water supply, and you will notice that the pH levels and ORP levels will not be where you need them to be.
Larger plates can conduct more electricity and therefore expand the ionizer’s ability to add alkaline elements to your water. Make sure you are not buying a model that boasts that it has 13 plates, but they are all super small. Ensure that the surface area of your plates is large enough and that you are getting everything possible out of your alkaline water filter.
PH and ORP Levels
We have discussed numerous things related to pH levels throughout this buying guide, but we will hit the important pieces again. pH refers to the water’s alkaline or acidic properties. If a pH level is below 7, then it is known to be acidic and is not as healthy as water with a pH level of about 7, which is referred to as alkaline water. The higher the pH the more alkaline the water is.
ORP stands for Oxygen-Reduction Potential. To make this as simple as possible, I will start by saying when looking at ORP levels, you want the number to be negative. The lower the ORP level, the more electrons the water will have free to combat the contaminants within your body.
Most systems will have the ability to customize your ORP levels, depending on how you want to use your ionizer at that moment. You can usually set the ORP level to between +600 and -600 on many ionizers.
For cooking, cleaning, and washing veggies, a positive ORP is not a big deal. When you are drinking water, you want the ORP to be in the negatives. This is because when you consume the water, the electrons within the water are available to do their jobs and give you the healthy benefits of alkaline water. ORP is measure in millivolts (mV) and you can test this by using an ORP meter.
Flow Rate
Most water filtrations systems, including alkaline systems, will reduce the flow rate of your water by at least a little bit. It makes sense because the water is running through several fine grain filters that are removing every contaminant it can find. Flow rates will vary from system to system, and it mostly depends on how fast the ionizing process takes within the electrolysis. The more plates and larger the surface area of the plates, the faster your water will be delivered.
Keep in mind, many of the models that we reviewed had multiple settings that you could choose from on the alkaline filter. If you choose to forego ionizing, then the water will be delivered quickly from the filtration system. Flow rates are extremely important to me, and I always look for a flow rate of at least 0.5 Gallons-Per-Minutes (GPM.)
Cleaning
Cleaning your alkaline filter will depend entirely on the system you buy. If you buy an under-sink water filter that has all the filtering and alkaline properties built into one system (non-electric,) then you will have a little more work to do with the cleaning. Filters will need to be flushed with cold water and shaken up to loosen the filtering particles.
If you decide that an electric ionizer is the best option for you, then there are a few notes to remember when it comes to cleaning them. If it has a built-in carbon or sediment filter, cleaning that will be separate from the cleaning of the ionizer. You will still need to back-flush pure water filters, as necessary. But when it comes to cleaning the ionizer and the alkaline system, you will have a much easier time.
Almost all the electronic ionizer systems now are self-cleaning models. And on top of that, most systems have a scheduled cleaning time, usually after each use. It uses reverse-polarity to wash the plates and ensure there are no leftover contaminants from the alkaline infusing process.
Installation
You will want to consider the installation difficulty when it comes to selecting your perfect alkaline water filter. There are two situations we will discuss here.
If you are looking for alkaline water filtering that is combined with an under-sink filtering system, you will need to install the full system. This entails connecting your current cold-water sink line to the filtering system so that you can use the water line that installs. Almost all these systems are simple enough to be installed by the homeowner, and many come with great instructions on video support to make it simple.
If you are looking for a higher-end ionizer, one that will most likely end up on your countertop, then the installation is a little bit different. These systems will require power and connection to the waterline. A lot of homeowners will be able to handle this on their own. But we do suggest ensuring that the alkaline filter you are going to purchase works for your space. Nearby power supply and access to connect it to the waterline.
Warranty
Like any consumer product, the warranty is extremely important. Accidents and issues will always occur during production, and it may end up being you who gets the only bad device from the manufacturer. Fear not, within the water ionizing world, warranties tend to be great.
You can find them up to 5 years, and many will go longer; some are even lifetime warranties. This is important to me when dealing with electric filtering, as things with more wiring can be damaged in shipment or anywhere along the manufacturing process.
If you are going with a higher-end alkaline system that has a few plates, remember to ensure that you can get replacement parts for the manufacturer in case any plates or specific parts are damaged over time.
Countertop Alkaline Filter Units vs. Under Counter Alkaline Units
When it comes to deciding on the style of alkaline water filter, there are some things to consider. There are pros and cons for each type, and you will need to decide which you prefer.
Countertop units are more popular when it comes to higher-end water ionizers.
They will connect to a power supply and water line, and you will have access to your alkaline water from the unit directly. The best part about the countertop units is that you will have access to adjust settings like pH levels and ORP without the need to crawl under your kitchen sink. A lot of them do have a sharp look to them and are ultra-modern, but some folks do not like losing the countertop space and prefer something hidden.
There are a few types of under-counter or under-sink units. Systems that combine standard filtration and alkaline filtering are very popular because they combine the water purification qualities of a filtration system and have a level where the alkaline properties are added to the water. They are hidden below the sink and out of sight. Because there is only one static level of alkaline properties within this style, you will not have as much customization over your alkaline water output.
There are some alkaline, electrical filters that are meant to be placed under the counter, and some even use their dedicated tap system. These are very high-end and can be expensive, but their water testing results speak for themselves. Remember, if an electrical unit is under the counter or sink, you will need to get down there to make any adjustments.
FREQUENTLY ASKED QUESTIONS & ANSWERED
Are alkaline water filters safe?
This is a very common question, and the answer is yes, for most people at least. Science has proven over time that the benefits of alkaline water can have positive impacts on the human body.
What are the dangers of drinking alkaline water?
In some cases, consuming far too much alkaline water can agitate your body’s normal pH levels, which may lead to nausea.
Do alkaline filters remove fluoride?
This is a common, but somewhat complicated question. The actual ionizing alkaline process does not remove anything. It is the filters that are combined with this process that do the work removing contaminants and toxins from the water. Check and see the filtering capabilities of your system to get an exact answer on fluoride. Many on the market will combine alkaline capability and fluoride removal.
How often do I have to change the alkaline filter?
The filters that come with the alkaline system will be changed depending on that specific filter’s longevity. They will range from 100 gallons up to 500, investigate how long the filters will last to avoid having to purchase them often.
Conclusion
At the end of the day, an alkaline water filter will have amazing benefits for you and your family.
