Your body relies on water. The human body is 60% water, it aids the process of delivering nutrients to cells and removing waste products. In fact, water is present in every cell of your body.

However, you constantly expel water. This can be via sweat, saliva, or even when you urinate. This water must be replaced, the average human can survive just three days without water. Although it is worth noting that a man once potentially survived 18 days without water.

Of course, not all water is the same. The water that comes out of your faucet has been treated to kill bacteria and remove debris. It also has chemicals added to boost bone and teeth strength. This doesn’t mean it’s guaranteed to be contaminated free or healthy.

Research suggests that the fluoride added to the water increases the risk of cancer. Equally, chlorine is added to kill bacteria and can have a harmful effect on the human body.

You can eliminate these contaminants by using a reputable supplier of reverse osmosis Sydney. A filter is fitted into your water supply line, eradicating contaminants. You’ll notice the difference in the taste. Filtered water, and in particular, water filtered by reverse osmosis, is probably the healthiest and safest water you can drink.

Other Types of Water

There are plenty of other options:

Spring water

Spring water comes straight from the ground, it’s source is deep in the earth and, at the source, it’s relatively pure. However, it has to rise through rocks and soil to get to the surface where you can drink it. During this process, it can pick up an array of contaminants that could make it unsafe.

Mineral water

Mineral water is essentially spring water that has had minerals added. Unfortunately, this means it is also potentially contaminated and may not be safe to drink.

It may interest you to know that the water treatment plant has to test their water daily. Bottled water companies only need to do it once or twice a year. They can’t be certain what’s in the water they’re supplying!


Rainwater seems like it would be pure. After all, water evaporates, leaving behind all contaminants, and then sits in the clouds, waiting to come back to Earth. Rainwater is pure when sat in the clouds. However, when it falls it passes through the atmosphere. As humans emit a huge array of pollutants into the atmosphere, the rainwater collects these on the way down.

In short, it’s a dangerous option to drink.

Most other water sources in the world are contaminated by environmental factors. Drinking them means potentially placing your life in harm’s way. That’s why the safest approach is to use a reverse osmosis water filter. You can always do some home water tests to see the difference in the water quality before and after the reverse osmosis filter.

Don’t forget, water is essential for your ongoing health. But, you don’t have to just drink water. Tea, coffee, and even infused water are viable options to maintain your water intake.
