Water is essential for life, making up a large portion of the human body and supporting nearly every bodily function. While tap water is commonly available, many people choose purified water because it undergoes additional treatment processes that remove contaminants, chemicals, bacteria, and impurities. Purified water is widely used for drinking, cooking, medical purposes, and industrial applications due to its high level of cleanliness.
In this guide, we’ll explore what purified water (also known as filtered water, treated water, processed water, decontaminated water, or refined water) is, its nutritional profile, science-backed health benefits, possible side effects, preparation methods, storage tips, and much more.
What is Purified Water?
Purified water is water that has undergone specialized treatment processes to remove contaminants, pollutants, microorganisms, heavy metals, and dissolved solids. The goal is to produce water that meets strict purity standards and is safe for consumption.
Common purification methods include:
- Reverse osmosis (RO)
- Distillation
- Deionization
- Carbon filtration
- Ultraviolet (UV) treatment
According to regulatory standards, purified water contains very low levels of dissolved substances and harmful contaminants. It can originate from groundwater, tap water, or natural water sources before undergoing purification.
