Which type of water is better – alkaline water or filtered water? Alkaline water and filtered water are two completely different types of water.

Alkaline water has an elevated pH. This means it is the opposite of acidic water. Alkaline water is better if you want to increase the pH of your water and neutralize excess acidity levels.

Filtered water has been treated to remove contaminants and toxins. It is a way of cleaning water. It purifies water by passing it through a water filter and removing particles and chemicals.

If your drinking water is contaminated and needs to be purified – filtered water is better. By filtering contaminated water you can make it safe to drink.


WHAT IS ALKALINE WATER?

Alkaline water is any water that has a pH above 7. The pH scale is used to measure how acidic or alkaline a substance is. It runs from 0-14. 

Anything below 7 is acidic, anything above 7 is alkaline, and 7 is neutral. The higher the value the more alkaline a substance is. Similarly, the lower the value, the more acidic a substance is.

Alkaline water has recently seen a surge in popularity. People claim that drinking alkaline water neutralizes excess acidity in the body and boosts health. However, there is no scientific evidence to support these claims.  For more information on alkaline water – see here.


HOW TO MAKE ALKALINE WATER

Filtered water is water that has been treated by passing it through a water filtration device to remove contaminants. 

Bottled mineral water and most tap water supplies are filtered to remove harmful contaminants to make the water safe to drink and taste better. 

To find out if you’re home water supply has been filtered and is safe to drink you should contact your local water provider.


TYPES OF FILTERED WATER

When discussing – what’s the difference between alkaline water and filtered water – we need to take a look at the different types of filtered water.  There are many types of water filtration technologies but the aim of every one of them is the same – to remove contaminants from the water.

Water filtration is used to make water taste better, look better, and safe to drink. Without water filtration, we would all be drinking dirty water. 

The four main types of water filters used in the domestic setting are activated carbon filter, ion exchange, reverse osmosis, and distillation.

Activated Carbon Filter

This is the most common type of water filter. It is regularly used in domestic water filtration devices. It uses an ‘activated-carbon’ medium to bind contaminants as the water passes through the filter. 

The contaminants are trapped inside the carbon medium while the water is free to pass through. Carbon filters are effective in removing the taste of chlorine, other chemicals, and a wide range of contaminants in your drinking water.

Ion Exchange

An ion-exchange water filter removes contaminants from water in the form of undesirable dissolved ions by replacing them with harmless ions of the same electrical charge from using an ion-exchange resin.

An ion exchange filter is inexpensive and effective for the removal of dissolved inorganics contaminants such as arsenic, fluoride, nitrates, uranium, and sulfates. They are also regenerable for continuous usage.

Reverse Osmosis

Reverse osmosis is an incredibly effective way of filtering water. The process removes up to 99% of all water contaminants to produce high-quality clean water.

Reverse osmosis filtration passes water through a semi-permeable membrane with a pore size so small – it allows water molecules to pass but blocks microscopic contaminants.

The pore size of a reverse osmosis filter membrane can be as small as 0.0001 microns. These membranes greatly reduce the presence of harmful metals, lead, mercury, and microbes.

Distillation

A distillation filtration system boils source water into steam before condensing it back into water. As water is transformed to steam it leaves behind its contaminants.

It then travels through the distillation apparatus in its gaseous form before being cooled to condense back into water. The filtered cooled water is then collected in a reservoir.

CONTAMINANTS IN DRINKING WATER

woman testing water in a lab

What are the most common contaminants found in drinking water? According to the United States Environmental Protection Agency there are five types of contaminants in our drinking water: physical, chemical, biological, and radiological.

Physical – sediment suspended in the water of rivers, lakes, and streams. Often caused by soil erosion.

Chemical – nitrogen, bleach, pesticides, metals, and toxins produced by bacteria, human or animal drugs.

Biological – organisms such as microbes and viruses. Often referred to as microbiological contaminants they include bacteria, viruses, parasites, and protozoa.

Radiological – radiological contaminants are hazardous unstable atoms that emit hazardous ionizing radiation. Cesium, uranium, and plutonium are examples of radiological contaminants. You definitely don’t want these in your drinking water.


frequently asked questions

IS ALKALINE WATER BETTER THAN FILTERED WATER?

Alkaline water and filtered water are two completely different types of water. Alkaline water is better if you want high pH water with higher than normal alkalinity.

Filtered water is better if you want clean, purified water.  It has been passed through a water filtration system to remove contaminants. Water filtration purifies water to remove harmful substances and make it safe for drinking.

IS ALKALINE WATER JUST FILTERED WATER?

No, alkaline water is not just filtered water. Alkaline water is a special type of water that has an increased level of alkalinity. It is the opposite of acidic water.

Alkaline water has a pH above 7. Some people drink it for its potential health benefits – but there is no evidence to back up these health claims.

WHAT’S THE DIFFERENCE BETWEEN IONIZED WATER AND DEIONIZED WATER?

water pouring from a bottle

Ionized water has been through an electrochemical process to create alkaline and acidic water. Deionized water is a type of purified water that has had impurities called ions removed. They are two completely different types of water.

Don’t confuse ionized water with deionized water. They are two very different types of water. Ionized water is used to create alkaline and acidic water. While ionized water is a type of purified water that has had electrically charged molecules called ions removed.


WHAT IS IONIZED WATER?

Ionized water is used to create alkaline water and acidic water. It uses a process called water ionization to turn regular water into ionized water.

It is a process used to create alkaline water and acidic water. These are collected separately and used for a range of popular household applications.

ALKALINE & ACIDIC WATER

Alkaline water has a high pH, falling between 7 and 14 on the pH scale. Alkaline water is popular for its potential health benefits which include better skin health, detoxification, and treating acid reflux.

Acidic water has a low pH, falling between 0 and 7 on the pH scale. It is used for household cleaning, sterilization, and skincare.


WHAT IS DEIONIZED WATER?

deionized water

Deionized water is a popular form of purified water. It involves removing impurities in the water called ions. The process is called water deionization.

For processes requiring purified water, these ions are regarded as impurities and need to be removed from the water. This is where ion removal or deionized water comes into play.

Ions are small particles that have an electrical charge. There are two types of ions in water, positive ions and negative ions. Positive ions are called ‘cations’ and negative ions are called ‘anions’.


WHAT IS IONIZED WATER USED FOR?

Ionized water can be split into two groups – ionized alkaline water and ionized acidic water. Each of these has a distinct range of applications.

Applications of Alkaline Water

  • Drinking-Water
  • Potential Health Benefits
  • Cooking Vegetables
  • Making Tea & Coffee
  • Dyeing Fabrics

Applications of Acidic Water

  • Household Cleaning
  • Watering Plants
  • Disinfecting Utensils
  • Washing Dishes
  • Skin Care

WHAT IS DEIONIZED WATER USED FOR?

water pouring into a pool of water

Deionized water is a popular form of purified water used in many commercial and household applications. It is used in settings that require a relatively cheap and readily available form of purified water.  See below for a list of its most common applications.

Automotive
Deionized water contains no salts making it a great choice for automotive applications. Salts can damage engines, so deionized water is used in windscreen wash, radiator fluids, and anti-freeze formulas.

Aquariums
It’s clean, fish-friendly, and a great water for aquariums and marine tanks.

Beauty Products
It’s the go-to water base used in the production of shampoos, moisturizers, and skin cleansers.

Hospitals
Deionized water is a popular choice for cleaning jobs in hospital settings where water purity is vital.

Industry
Frequently used in industrial settings as a water rinse due to its high purity and very low salt levels. Salt corrodes and damages metallic equipment and fittings.

Laboratories
Many laboratory procedures require the use of deionized water in bench work and for cleaning utensils.


HOW IS IONIZED WATER MADE?

lasy drinking a glass of alkaline water

The easiest way to make ionized water is using a water ionizer. This a machine that takes regular tap water and converts it to ionized water.

The device used an electrochemical process to ionize the water and convert it into alkaline and acidic water. All you need to do is add water to the machine and let it get to work.

Using high conductivity electroplates it separates water into hydrogen and oxygen molecules. If there are a greater number of H+ ions than OH- ions the water is acidic.

If the number of OH- is greater than the number of H+ then the water is alkaline.  Check out the Best Alkaline Water Ionizers  – see here.


HOW IS DEIONIZED WATER MADE?

Deionized water is made using an ion exchange resin. These resins contain tiny beads that have electrical charges that are used to attract and remove the ion impurities contained in water.

The positively charged beads are used to attract and remove the negative ions in the water. And, the negatively charged beads remove the positive ions in the water.

As the water passes through the filter resin both types of ion are held in place and purified water flows from the filter.

Ion exchange filters have a limited lifespan and lose charge as they purify water. They need to be replaced and regenerated when they reach the end of their life cycle.


WHAT ION IMPURITIES ARE REMOVED?

Regular water is full of ions that it picks up as it moves through rocks and passes through pipes. It collects these minerals naturally as it brushes up against them. Deionization removes these minerals using their positive (cation) or negative (anion) molecular charge.

Cation Impurities Removed

  • Magnesium
  • Iron
  • Calcium
  • Manganese
  • Hydrogen
  • Sodium

Anion Impurities Removed

  • Sulfates
  • Nitrates
  • Chlorides
  • Carbonates
  • Hydroxyl
  • Silica

THE BOTTOM LINE – THE DIFFERENCE BETWEEN IONIZED WATER AND DEIONIZED WATER?
