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.

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 make the water “alkaline,” which can neutralize body acid. There is evidence that alkaline water will benefit 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?

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.

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 drinking water, we do not refer to it as alkaline until it reaches 7.5 or higher.

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 alkaline water's benefits can positively impact the human body.

What are the dangers of drinking alkaline water?

In some cases, consuming too much alkaline water can agitate your body’s normal pH levels, leading 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 filters?

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.

6. EHM Ultra Premium Alkaline Water Pitcher

Highlighted Features

This self-filtering pitcher holds up to 3.8 liters of water, and a filtered water reservoir that holds 2 liters of purified water.
The filtering qualities that the EHM possesses use micro-clustering to reduce water molecule size. This helps make the water alkaline, free from radicals and toxins.
The EHM alkaline filter has 6 stages and can adjust the water’s pH level to 10 depending on the water source. It will usually increase water by a minimum of 1-2 pH counts.

The EHM alkaline water pitcher is amongst the best in its class when it comes to self-filtering water pitchers.

EHM revolutionized this filtering type by fitting a 6-stage water filter into a small, compact water filtering pitcher.

It has a wonderfully ergonomic design that allows you to easily handle the pitcher, and even though it fits 3.8 liters of water, it will easily fit in your refrigerator’s door. When it comes to its filtering capabilities, it will remove all the common contaminants found in most municipal water supplies and then some. The entire pitcher is made from 100% BPA-Free, food-grade materials, which helps eliminate micro-organisms that may sneak through the filtering process.
