Distilled Water vs Reverse Osmosis Water: Key Differences

When it comes to choosing between distilled water and reverse osmosis water, there are a few key differences that you should be aware of. In this section, we will compare the two processes and their outcomes on water purity, taste, mineral content, and cost-effectiveness.

Purity Levels

Both distilled water and reverse osmosis water are considered to be highly pure forms of water, with most contaminants removed. However, the level of purity achieved by each process is slightly different.

Distilled water is produced by boiling water until it evaporates, then condensing it into a separate container. This process removes most contaminants, including minerals, bacteria, and viruses. However, some volatile organic compounds (VOCs) and gases may still be present in the water, as they have a lower boiling point than water.

Reverse osmosis water, on the other hand, is produced by filtering water through a semi-permeable membrane. This process removes most contaminants, including minerals, bacteria, viruses, and VOCs. However, some dissolved solids may still be present in the water, as they are not filtered out by the membrane.

Removal of Contaminants

Both distilled water and reverse osmosis water are effective at removing contaminants from water. However, the specific contaminants that are removed by each process may differ.

Distilled water is particularly effective at removing minerals, as they have a higher boiling point than water and are left behind during the distillation process. However, some VOCs and gases may still be present in the water, as they have a lower boiling point than water.

Reverse osmosis water, on the other hand, is particularly effective at removing dissolved solids, such as salts and minerals. However, some VOCs and gases may still be present in the water, as they are not filtered out by the membrane.

Taste and Mineral Content

Distilled water is often described as having a flat taste, as it lacks the minerals that are naturally present in water. This can be both a pro and a con, depending on personal preference. Some people prefer the taste of distilled water, while others find it bland.

Reverse osmosis water, on the other hand, may still contain some minerals, as not all minerals are removed by the membrane. This can give the water a slightly different taste than distilled water. However, the taste of reverse osmosis water is generally considered to be better than tap water.

Cost-effectiveness

When it comes to cost-effectiveness, both distilled water and reverse osmosis water can be expensive to produce. Distilled water requires a significant amount of energy to produce, as it involves boiling water and condensing the steam.
