What’s The Difference Between Distilled And Purified Water?

Purified and distilled water is important in today’s society: providing extra protection for clean drinking water. Various methods are utilized to create purified water, including distillation, reverse osmosis, ion exchange, and occasionally ozonation to eliminate impurities like chemicals or bacteria.

Distilled water, conversely, only undergoes the distillation process to eliminate impurities. These two purification methods are beneficial since certain minerals present in tap water can be eliminated.

There are three types of water: purified, distilled, mineral, and spring water. Access to clean drinking water is essential for maintaining good health. In developed countries such as the US, tap water is carefully monitored and considered safe for consumption.

Some people use purified or distilled water instead of tap water for extra safety. Filtered water is safer for those with taste preferences or health concerns. Read on to learn more about it.

Introduction of Purified Water

Purified water has been thoroughly filtrated to remove unwanted contaminants and impurities such as bacteria, parasites, and fungi. These processes often involve mechanical filters, carbon filtration, sand beds, reverse osmosis filters, sediment pre-filtration, and ultraviolet or ozone treatment.

It is an ideal source of safe drinking water for homes and businesses as it has virtually no microorganisms present after these filtration processes.

The safety of purified water over untreated tap or well water is widely recognized – numerous studies have concluded that it typically contains lower levels of organic compounds, such as Chlorine by-products which can be carcinogenic (cancer-causing).

Using purified water in all applications, from industrial cooling systems to medical procedures, exceeds the safety requirements of untreated raw sources. This makes it a much more desirable option for most demands requiring the elimination of microbial risk due to its added assurance of high rejections rates for all potential contaminants.


Purified water is widely accepted to be the healthiest type of water to drink, thanks to its lack of contaminants found in tap water.

While tap water is generally safe to consume in most developed countries, it still often contains a variety of contaminants that can potentially be hazardous to your health. Therefore, many people choose to drink purified water because of its numerous benefits.

Purified water is safer because it removes chlorine, toxic metals, organic matter, harmful chemicals, and bacteria. Drinking purified water regularly is good for your colon and digestion. Drinking purified water helps keep the body hydrated and aids in digestion.

Clean water can strengthen the immune system by removing harmful toxins. All this makes consuming pure drinking water an absolute necessity for healthy living.


One of the major drawbacks is that the purification process often removes helpful minerals from the water, such as fluoride. Fluoride has been proven to reduce tooth decay and improve overall dental health.

Therefore, if you are choosing to drink purified water, it may be worth looking into other ways to get your daily dose of fluoride, such as chewable tablets or brushing with fluoridated toothpaste.

Another issue with purified water is that many purification systems must be regularly maintained to ensure contaminants do not build up inside filters. Homeowners must regularly replace filters or call technicians to maintain their HVAC system, which can be costly.

Choose a purification system carefully, as some methods may not remove all contaminants like pesticides. The cost of purified water depends on consumption and system installation.

Introduction of Distilled Water

Distilled water is a type of purified water produced through a distillation process. The process involves boiling water, collecting steam, and cooling it back to liquid form. Distilled water is free from impurities and has low electrical conductivity ranging from 0.5 to 3 µS/cm.

It effectively removes contaminants such as bacteria, viruses, and other chemicals from the source water supply.

Distillation is an important process used in many industries due to its ability to remove certain contaminants from the source material completely. It does not require additional chemical treatments or additions, making it more economical than reverse osmosis (RO) or ion exchange processes.

The only disadvantage of distilled water is that some vitamins and minerals can be removed by distillation. However, this can be compensated by adding these back into the end product when necessary or desired.


Distilled water has many health benefits. It is considered the purest form of water available, as all other impurities – contaminants, minerals, and pathogens – are removed during the distillation process.

Unlike other forms of purified or filtered water, distilled water does not contain any particles or residues that could be left behind by the filters used for purification. This makes it ideal for medical applications or those with certain conditions, such as allergies to particular tap or mineral water substances.

Drinking distilled water reduces lead and chemical risks as it’s free of minerals and impurities. Distilled water can stop kidney stones by preventing mineral salt buildup in the kidneys and urinary tract. Drinking distilled water can improve bodily functions by balancing electrolyte and pH levels for better health.


Despite distilled water being one of the cleanest and purest types, it has many potential drawbacks. Distilled water requires a significant amount of energy for purification processes, making it one of the more inefficient ways to clean water. This inefficiency harms the environment more than other methods, such as reverse osmosis.

One of the biggest cons of drinking distilled water is that it removes electrolytes and natural minerals from the body.

These minerals – such as magnesium and calcium – are essential for human health, and drinking distilled water can potentially inhibit these nutrients from entering the body.

The lack of minerals can increase risks such as heart disease, fractures, and preterm birth. To make matters worse, most distillation methods also remove all traces of fluoride, which can harm dental health over time due to a lack of strengthening properties in tooth enamel.

Which Is Better To Drink: Purified Water Or Distilled Water?

Purified and distilled water are both options that offer consumers clean, healthy drinking water. The main difference between the two is that purified water still contains vital minerals and nutrients, which provide essential benefits to the body. By contrast, distilled water lacks all minerals and will not contribute any health benefits.

For those concerned about pollutants in tap water, either option is great for removing potential contaminants from consuming unclean liquids, so both forms are ideal for people who want safe drinking water free from any unwanted particles

However, if you need the purest possible form of H2O, distilled water will be your best choice due to its lack of naturally-occurring minerals or trace elements.

On the other hand, those looking for more nutrient-rich drinking water may choose purified instead to enjoy some semblance of health benefit.

Whatever you make regarding purified or distilled water will ensure you receive a healthier alternative than regular tap water.
