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 do 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 always has additional minerals added, 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 who consume water with a high pH level will have increased oxygen delivery throughout the body. Alkaline water can also help with immune system support, weight loss, and healthier skin and nails.

What are 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?

best chlorine water filter reviews

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 run the water through it before it hits the alkaline filter. The best water 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 separate alkaline filters, 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. The answer is both when it comes down to which is better alkaline, or filtered water.

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 alkaline filter’s ionization process, even water running 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.

đź§ľ How To Buy an Alkaline Water Filter. What To Look For.

how to buy an alkaline water filter

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 attack the ionization process and do not have 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 system 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; if you buy 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 essential features of the alkaline ionization process is the material and number of plates that are used. If the filter you purchase is designed to be used with electricity, 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 deciding on an electric water ionizer, there are a few things to consider.

Number of Plates

Most systems 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 solid number 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, 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 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.

Platinum is the best option because it is proven to be the best metal at speeding up electrolysis. Thousands of different metal compounds have been tested, which 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 expand the ionizer’s ability to add alkaline elements to your water. Make sure you are not buying a model that boasts 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 essential pieces again. pH refers to the water’s alkaline or acidic properties. If a pH level is below 7, it is known to be acidic and is not as healthy as water with a pH level of about 7, 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. On many ionizers, you can usually set the ORP level to between +600 and -600.

For cooking, cleaning, and washing veggies, a positive ORP is not a big deal. When 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 measured 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 remove every contaminant it can find. Flow rates will vary from system to system, depending on how fast the ionizing process takes within the electrolysis. The more plates and the larger the surface area of the plates, the faster your water will be delivered.

Keep in mind, that 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, 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 with all the filtering and alkaline properties built into one system (non-electric), you will have a little more work to do wit
