Purified Water vs Tap Water: What’s the Difference?
Monday, November 15, 2021

Water makes up 50-70% of our body weight.

Men should drink about 15 cups of water per day while women should drink 11 cups per day. Not drinking enough water leads to severe dehydration and other health issues.

On top of drinking water, you should also be paying attention to the type of water you're drinking. Yes, that's right. There are different types.

Below is a guide on purified water versus tap water. Keep reading below to discover the difference between the 2.

Tap Water

When we drink from our faucet, we're drinking tap water.

The main sources of tap water include lakes, rivers, and groundwater. In some cases, it even comes from wastewater.

The treatment tap water receives is limited to filtration systems provided by the city/region. It's fairly safe for consumption, but it's possible that certain pesticides and other contaminants are still present after treatment.

Are There Any Benefits?

Believe it or not, there may be some benefits to drinking tap water. Some naturally occurring minerals you might find in tap water include magnesium, sodium, and calcium.

What's found in the water varies depending on the source and the city. Different cities have different purification processes.

Purified Water

Instead of sipping from the sink, many people turn to purified or bottled water.

Purified water started as tap water but has undergone intense cleaning and disinfecting methods. A variety of bacteria, parasites, and pollutants have been removed in purified water.

How Is Water Purified?

There are several components to the purification process. These components include coagulation and flocculation, sedimentation, filtration, and disinfection.

Coagulation and Flocculation

In this step of the process, positively-charged chemicals mix in with the water. These positive chemicals pair up with negatively-charged particles to form flocs.


Flocs are large and heavy. They settle at the bottom of the water.

They're removed through sedimentation, along with any other large particles in the water.


Clean water flows through a variety of filtration systems. These different systems remove any sand, dirt, chemicals, and viruses found in the water supply.


Disinfectants, such as chlorine, are added to the water. They kill off anything left behind after the first few steps of purification.

It's important to read up on what disinfectants have been used before consuming bottled water.

Advantages vs Disadvantages of Purified Water

Those who drink purified water always claim it tastes fresher and better than tap water. In many cases, it's also safer to drink than tap water.

However, there are some downsides to drinking purified water. One major downfall is the possibility of unsafe fluoride levels. High levels of fluoride can be toxic to the brain.

It's also extremely expensive to maintain water purification systems. They require consistent maintenance.

Purified vs Tap: Which Is Better?

Water is crucial to our survival. Therefore, it's important to know what's in your water.

Tap water comes from lakes, rivers, and groundwater, and it can contain a variety of contaminants. Purified water is tap water that's filtered and disinfected.
