Distilled Water Vs. Purified Water – What’s the Difference?

Distilled Water Vs. Purified Water – What’s the Difference?

While dining with your loved ones at a fancy restaurant, the waiter clad in expensive attire has probably asked you whether you would prefer tap water, bottled, or sparkling water? And although this array of options for something as simple as water may have left you reeling, there is yet another selection; distilled water or purified water? Read the information below to apprise yourself of the differences between the two.

What is Distilled Water?

An entire process happening in controlled conditions leads to a distilled water formation, which many people claim is the purest form. First plain water undergoes boiling such that it produces steam. Experts then cool the vapor forming liquid again. This is known as distilled water. Since people collect water from external sources; a spring, well, or lake, it is bound to have multiple impurities like bacteria, pesticides, and other contaminants. Distilling water eliminates all these pollutants, making it pure to drink. Also, it hardly has any minerals which are supposed to be present in regular water.

What is Purified Water?

Experts prepare purified water typically by subjecting it to mechanical filters such as reverse osmosis, carbon filtering, microfiltration, and ultrafiltration. The purpose of these sophisticated techniques is to purify the water in varying degrees to make it appropriate for the formation of medications and different processes in science and engineering laboratories and industries.

Differences Between Distilled Water and Purified Water – Which is Better?

As you can probably deduce, essentially, both forms of water are similar. The only distinction between the two is the purification technique that experts employ, resulting in slightly variable quality. Hence, the primary difference between distilled water and purified water is that the former is free of all impurities and contaminants while the latter is treated water which is subjected to several processes to remove some impurities and leave the rest per requirement.

Purified water typically contains bacteria, fungi, algae, metals, and pesticides before its treatment. In contrast, distilled water which is a form of purified liquid, contains nutrients such as minerals, chemical pollutants, parasites, bacteria, and viruses before it undergoes distillation. Later distilled water is entirely free of impurities and mineral salts unlike, purified water so, it is not suitable for consumption in average individuals. This is because the human body requires mineral ions for conducting nerve impulses. It is fitting for immunocompromised individuals whereas, purified water is ideal for maintaining digestive health since it still contains mineral salts that facilitate the digestion of food in the body. Hence, while distilled is the purest form of water, experts consider purified water to be the best option for consumption.

However, purified water can lead to dental caries because it removes fluoride. Additionally, you need to maintain the purification system regularly to ensure that water treatment is up to the mark. Also, people claim that purified water bottles damage the environment since they are difficult to decompose. Distilled water can also get contaminated very easily from any pollutants in the water bottle.

The multitude of purification methods eradicates chlorine in the water, which is the typical chemical behind the increased occurrence of colorectal and similar cancers. Purified water is also free of detrimental bacteria that can lead to nausea and stomach aches once ingested. It also supplies your skin with a protective barrier to fight off impurities. Similarly, experts recommend drinking distilled water if your immune system is weak – any germ that gains entry into your body via food or drink can have a life-threatening impact on you since it is the safest type of water available.


With the boundless development in technology, experts can control water purity according to their needs by utilizing an array of innovative procedures. One such process involves using a water softener to eliminate minerals that make water harsh. This is one of the most typical problems a homeowner has to battle since hard water results in a soapy residue across kitchen and bathroom tiles, ruins appliances, and sucks out moisture from hair and skin. By installing a water softener, you can prevent all this damage by simply removing all the mineral salts from the water which enters your house.

At last, we must say that there are pros and cons to both categories of water. Hence, you should decide which option is best for you and your family members.
